Root System and Shoot System
The two main parts of a plant are the root and the shoot. The part growing below the ground is the root system. The part above the ground is the shoot system: stem, branches, leaves, flowers and fruits.
Roots
| Tap root | Fibrous root |
|---|---|
| One main root with small roots growing sideways from it; root hairs absorb water | A bushy bunch of thin roots growing from the base of the stem; main and side roots look alike |
| Bean, carrot, pea, mango | Grass, wheat, rice |
Functions of roots: they fix the plant firmly in the soil; they take in water and minerals and pass them to the stem; they hold the soil and prevent soil erosion; some roots store food (carrot, radish, turnip, beetroot).
Fun facts: roots of the banyan tree hang from its branches, reach the ground and become thick like trunks. Many cacti have roots that spread wide but go only a short way into the soil.
Stem
The stem bears branches, leaves, buds, flowers and fruits. Stems are strong and woody in trees (teak, mango), soft and green in herbs (mint, banana), and woody but thin in shrubs (rose).
Functions: keeps the plant upright; carries water, food and minerals to all parts; stores food (sugarcane; underground stems of potato and ginger); stores water (thick fleshy stems of desert cacti).
Leaf
| Part of a leaf | Meaning |
|---|---|
| Leaf blade (lamina) | Flat broad part |
| Midrib (main vein) | Line in the centre of the leaf |
| Side veins | Lines on either side of the main vein |
| Petiole (leaf stalk) | Joins the leaf to the branch |
Leaves are the food factory of a plant. Chlorophyll, the green substance, absorbs sunlight, and the leaves make food from air (carbon dioxide), water and sunlight. This is photosynthesis. Tiny openings under the leaf, the stomata, let air in. Leaves release water vapour, which keeps the plant cool. Methi, spinach and mint store food in their leaves. New plants grow on the edges of Bryophyllum leaves.
Flower, Fruit and Seed
Flower: the most colourful part; it grows from a bud. Most flowers change into fruits, but the lotus flower does not. Flowers attract birds, insects and other animals that help the plant to reproduce. Cauliflower and broccoli are eaten flowers. Rafflesia is the largest flower in the world.
Fruit: formed from a flower; it has seeds inside and stores food. Some fruits, like peas, are cooked as vegetables. Strawberries have their seeds outside.
Seed: has a baby plant protected inside. Seeds germinate into new plants and are used as dry fruits (cashew), for oil (mustard), flavour (fenugreek), pulses (moong) and cereals (rice). Germination is the growth of a new plant from a seed with water, air and warmth.
Questions and Answers
1. Define leaf blade, petiole and germination.
Show answer
Answer: Leaf blade: the flat broad part of a leaf. Petiole: the leaf stalk that connects the leaf to the stem. Germination: the growth of a seed into a new plant.
Teacher's Note: Use the key term in your answer.
2. What is the midrib?
Show answer
Answer: The line in the centre of a leaf, also called the main vein.
Teacher's Note: Give an example if the question allows.

| Bean, carrot, mango | Grass, wheat, paddy |
Teacher's Note: Remember this for your exam.
5. Write the difference between the root system and the shoot system.
Show answer
Answer:
| Root system | Shoot system |
|---|---|
| Grows below the ground | Grows above the ground |
| Tap and fibrous roots fix the plant to the soil | Stem, branches, leaves, flowers and fruits |
Teacher's Note: Learn this point and write it in your own words.
6. What are the functions of fruits and seeds?
Show answer
Answer: Fruits protect the seed, help plants spread seeds, and are eaten as food. Seeds contain food for the baby plant, grow into new plants, and many are eaten, such as beans, corn, rice, pepper and cumin.
