Chapter: 3rd Science : Term 2 Unit 3 : Plants

Plants

Learning Objectives

After learning this lesson, students will be able to

  • * identify the parts of a plant
  • * understand the functions of different parts of a plant
  • * classify plants based on their habitat
Unit 3
Plants
Plants Unit Header

Warm-up

Unscramble the words and label the parts of the plant.

( ETSM, TORO, ELFA, FURTI, LOFEWR , SDEE )

Plant Parts Diagram

I. Plants are nature's gift

A plant has many parts. Each part has a set of function to do.

The basic parts of a plant are root, stem, leaf, flower, fruit and seed.

Let us learn about various parts of the plant, their structure and function.

Root

The root is a part of the plant that usually grows under the soil. Roots can be of different shapes and sizes. It grows away from sunlight into the soil. They are of two main types: tap root and fibrous root.

Taproot

Taproot has one main, thick root. It grows from the radicle and goes deep into the soil. Many small thin roots grow out from the main root. Plants such as carrot, beetroot, turnip, mango and neem have taproots.

Taproot

Fibrous Root

A fibrous root consists of many thin roots of different sizes. They grow from the base of the stem and all of them are bunched together. They do not go deep into the soil. Plants such as grass, paddy, wheat and onion have fibrous roots.

Fibrous Root

Functions of Root

Fixation: Root fixes the plant firmly to the soil. Without the roots, a plant would fall on the ground.

Absorption: Roots absorb water and minerals required for the plant from the soil.

Storage of food: In some plants, roots store food. E.g., Carrot, Radish, Beetroot.

Difference between taproot and fibrous root

Root Difference Table

Taproot:
Thick main root that goes deep into the soil.
Side roots are developed from the main root.
Looks like a long tap E.g., Tamarind, Guava.

Fibrous root:
No main root and the roots do not go deep into the soil.
Roots are developed from the base of the stem.
Looks like a bunch. E.g., Corn, Sugarcane.

Do you know
Avecinnia plants have roots above the ground. Avecinnia roots

Let us Do

Take two small potted plants. Cut the root of one of the plants and fix it in the pot. Now water the plants for two to three days. You will observe that the plant without roots will wilt and die. In the absence of roots, plants die.

This acivity proves that the function of the roots is to absorb Water and Minerals from the soil.

Let us Do

Take two coconut shells. Fill them with soil. Sow green gram in one and paddy in another. Keep them under sunlight and water them. After a week observe the features of roots.

Let us Write

True or false

Writing Activity
1. The roots grow into the soil. (True)
2. Fibrous root has a main root. (False)
3. Root absorbs water from soil. (True)
4. Potato stores food in its root. (False)
5. Grass has fibrous roots. (True)

Stem

The stem is the main part of the shoot system. It grows towards the sunlight. It looks green when it is young. Branches, leaves, buds, flowers and fruits grow from the stem.

Stem Diagram

Herbs such as coriander and mint have a thin and weak stem. Trees such as peepal and banyan have very strong and thick stem called trunk. As trees grow older, their trunks grow wider.

Functions of the Stem

  • * It supports the whole plant.
  • * It transports food from leaf and water from root to various parts of the plant.
  • * Some stems store excess food in them. E.g., Potato, Onion.
Potato and Onion

Leaves

Leaves originate from the surface of the stem. It is flat, thin and green. Leaves of different plants have different shapes, sizes and colours. Some leaves have even a specific smell.

Types of Leaves

Functions of Leaf

  • * Leaf prepares food for the plant with the help of water, carbon dioxide and in the presence of sunlight and chlorophyll. This process is called photo synthesis. Hence, it is called the food factory of the plant.
  • * The loss of water in the form of gas (water vapour) happens through the tiny pores in the leaves. This process is called transpiration. It gives cooling effect to the plant.
  • * Leaves of some plants are edible and rich in nutrients. E.g., Greens, Cabbage.

Let us Play

Collect the leaves of coriander, mint, eucalyptus, tamarind, amla, neem and tulsi.

Select two students and cover their eyes with a handkerchief. Give one leaf to each of them. and ask them to identify the leaf by touching or and the other by smelling it. Find out who identifies more leaves.

Leaf Identification Activity

Which method is easier to identify?

Touching or smelling?

Answer : smelling

Let us Do

Collect the leaves of different kinds of plants.

1. Arrange the leaves from small to big.
2. Group the leaves based on its colour.

Let us Write

Fill in the blanks.

1. Stem grows towards the sunlight.
2. Leaves originate from the Stem.
3. Green part of the plant that makes food is called Leaf.
4. Stem gives support to the whole plant.
5. Water from soil is absorbed by the root of the plant.

Flowers

Flowers are the most beautiful part of the plant. They are of different shapes, size, colours and fragrance. A flower develops from the bud. The soft and brightly colored part of a flower is called petal. The green part that lies under the petal and supports it is called sepal. The middle of the flower has two parts called the stamen and pistil.

Parts of a Flower

Functions of the flower

  • * It develops into fruit.
  • * It helps plant to reproduce.

Fruits and Seeds

Fruit is the fleshy part of the plant. The fruits are developed from the flowers. Most fruits have seeds.

  • * Some fruits have only one seed. E.g., Apricot, Mango, Coconut and Peach.
  • * Some fruits have many seeds. E.g., Papaya, Watermelon and Orange.
  • * Some are seedless. E.g., Pineapple and Banana.
Fruits and Seeds

New plants are grown from seeds.

Think and Write

1. List out the fruits that do not have seeds. Banana, pineapple.
2. Write down the names of the fruit trees that you have never seen, but have tasted their fruits. apple, strawberry.

Let us Do

Connect the leaf with its fruit.

Connect Leaf with Fruit

IV. Plants and their habitat

Plants grow almost everywhere on Earth i.e. on land (terrestrial plants) and in water (aquatic plants). The plants adapt to their surroundings and hence have special characteristics based on their habitat.

The natural home of a plant is called its habitat. Plants make suitable adjustment with their surroundings to meet their requirements. This is known as adaptation.

Terrestrial or Land Plants

The plants that grow on the land are of different habitats such as deserts, plains,mountains and forests. Let us learn about the adaptation of different land plants.

Plants in Desert

These plants grow in hot, dry and sandy places. Deserts get very less rainfall and experience high temperature. Hence, there is scarcity of water. Let us see how these plants have adapted to this habitat.

  • * Leaves are changed to spines to reduce the loss of water.
  • * The stem is green and fleshy. They store water and produce food.
  • * These plants have a long root that goes deep into the soil.

E.g., Opuntia, Date Palm and Aloe vera.

Desert Plants

Plants on Mountain

These plants grow in cold and freezing places. There is a cool weather in mountain. Let us see how these plants have adapted to this habitat.

  • * These trees are conical in shape. This shape allows snow to slide from the trees easily.
  • * Needle like leaves help them to survive in cold conditions like snow.
  • * These trees do not shed leaves.
  • * They have cones instead of flowers. These cones protect the seeds during harsh winter. E.g., Pine tree.
Mountain Plants

Plants in Plains

  • * Plants in plains need to adapt to both dry conditions and extreme temperatures.
  • * They grow in warmer climate and usually shed their leaves in winter to protect themselves from cold.
  • * They have flat and broad leaves.
  • * They have thick and woody stem. E.g., Mango, Banyan, Teak.
Plants in Plains
Do you know
Banyan, Peepal and Tamarind trees live more than hundred years.

Plants in Coastal Areas

  • * They are tall and mostly straight.
  • * The leaves are called frond.
  • * The frond look like feathers meant for protection from wind.
  • * These plants tolerant to saline (salt) water. E.g., Coconut tree.
Coconut Tree

Let us Connect

Match the plants with their living places.

Match Plants with Habitat

Let us Try

Tree   Ocean   Desert   Cave

V. Plants in Water

The plants that grow in water bodies like ponds and lakes are called water plants or aquatic plants. They are classified into following types.

  1. Free floating plants
  2. Fixed rooted plants
  3. Submerged plants

1. Free Floating Plants

  • * These are found on the surface of the water.
  • * They freely float with the help of spongy body filled with air.
  • * They have poorly developed roots.

E.g., Water hyacinth (Agaya thamarai), Pistia.

Free Floating Plants

2. Fixed Rooted Plants

  • * These plants have root that are fixed in the bottom of the water bodies.
  • * These plants have air tubes in their stem to help them float.
  • * Their leaves are broad and coated with wax to make them water proof.

E.g., Water lily, Lotus.

Fixed Rooted Plants

3. Submerged Plants

  • * These plants are completely submerged in the water.
  • * Their stem is thin and leaves are very small.
  • * There is no opening on the leaf surface.
  • * They breathe through stem. E.g., Vallisneria, Hydrilla.

c. The food items which can be eaten in small quantities are indicated by green colour.

I. Food Nutrients

Think: Why do you eat every day? What happens if you don’t eat sometimes?

Every day we feel hungry and then eat something. Our body is telling us that it needs food.

Why do we need food?

1. Food gives us energy to work and play.
2. Food builds our body.
3. Food keeps us healthy.

We eat different food items, some are raw and some are cooked. Each of these food items contains different nutrients. There are five main nutrients that our body requires. They are carbohydrates, proteins, fats, vitamins and minerals.

Do you know: World Food Day is observed on October-16.

1. Carbohydrates

Our body needs energy to do work, play and do other activities. Carbohydrates are energy-giving food. Food that contains carbohydrate are rice, wheat, potato, sugar cubes and bread.

Carbohydrate food sources

2. Proteins

Proteins build, maintain and replace the tissues in our body. They are also known as body - building foods. E.g., Fish, Milk, Egg, Nuts and Sprouted seeds.

Protein food sources

3. Fats

Fats provide energy to us. They act as the body’s energy reservoir. Fats also help to keep the body warm during very cold weather. Too much fat in the body may lead to obesity or overweight. Some food items that contain fat are cheese, butter, ghee, meat, oil and nuts.

Fat food sources

4. Vitamins

Our body needs vitamins to work properly. They protect our body from deficiency diseases. E.g., Carrot, Orange, Gooseberry, Papaya and Greens.

Vitamin food sources

5. Minerals

Minerals help in formation of blood, bone, teeth, etc. They regulate the body functions. E.g., Fig, Pear, Garlic, Banana and Apple.

Mineral food sources

II. Balanced diet

Diet refers to the food we eat. A balanced diet contains all nutrients in the right amounts. It also includes fibre and water. It helps in the growth and development of our body.

The quantity of nutrients required by our body and their sources can be shown by a food pyramid. The food item that should be eaten in the least amount is kept at the top of the pyramid.

A balanced diet food pyramid is shown here.

Food Pyramid

Roughage, also known as fibre is an indigestible food that your body cannot absorb. It is present in food such as legumes, whole grains and vegetables.
