E. Short Answer Questions (15 Marks)
1. Seed dispersal is the process by which seeds are spread away from the parent plant. It is important so that all plants get enough space, water, sunlight, and nutrients to grow well.
2. Steps of germination:
Seed absorbs water and warmth.
Seed coat breaks, root comes out.
Shoot grows upward, leaves come out and start making food.
3. Agents of seed dispersal:
Wind → e.g., dandelion
Water → e.g., coconut
Animals → e.g., cocklebur
4. Vegetative reproduction: Some plants grow from their parts like roots, stem, or leaves.
Examples: Rose from stem, Potato from eyes (buds).
5. Fertilisers give important nutrients to the soil to help plants grow better. They increase crop quantity and quality.
1. Explain the life cycle of a plant. (5 marks)
Answer:
The life of a plant starts from a small seed. This seed grows into a baby plant and then into a big plant. Let’s understand step by step:
1. Seed – Every plant begins its life as a seed. Inside the seed, there is a tiny baby plant called an embryo.
2. Germination – When the seed gets water, air, and warmth, it starts growing. This is called germination. First, the root comes out, then the shoot.
3. Sapling – After a few days, the seed becomes a small plant with green leaves. This small plant is called a sapling.
4. Mature Plant – The sapling grows bigger and becomes a mature plant. Now it starts growing flowers.
5. Flower to Fruit – Flowers help in making fruits. Inside the fruits, there are new seeds.
6. New Life – These seeds fall on the ground and grow into new plants.
This circle from seed to seed is called the life cycle of a plant.
2. How do animals help in seed dispersal? Give examples. (5 marks)
Answer:
Animals, birds, and humans help in spreading seeds to far places. This helps the plant to grow in new areas. There are three main ways:
1. Seeds stick to their bodies – Some seeds have tiny hooks or spines. These seeds stick to animal’s fur or human clothes and go to new places.Example: Cocklebur seeds
2. Seeds in animal droppings – Animals or birds eat fruits. The seeds inside come out in their potty (droppings) and grow into new plants.Example: Mango, cherry, jamun seeds
3. Storing and forgetting – Some animals like squirrels collect nuts and hide them under the ground. Sometimes, they forget, and these nuts grow into plants.Example: Peanuts, walnuts.
So, animals are very helpful in spreading seeds and growing new plants.
3. Describe the difference between monocot and dicot seeds. (5 marks)
Answer:
Seeds are of two types – monocot and dicot. Let’s see how they are different:
| Feature | Monocot Seed | Dicot Seed |
| | – | |
| Cotyledons | Has one seed leaf | Has two seed leaves |
| Examples | Rice, wheat, maize | Peas, beans, gram |
| Splitting | Cannot be split easily | Can be split into two parts |
| Food Storage | In one part | In two parts |
4. Explain how crops are grown. Write any five main steps. (5 marks)
Answer:
To grow crops, farmers follow some steps. These steps are:
1. Ploughing – First, the farmer loosens the soil using a plough. This helps air and water to reach plant roots.
2. Sowing – Seeds are put into the soil carefully. Only healthy and good quality seeds are used.
3. Adding fertilisers – Fertilisers (manure or urea) are added to make the soil rich in nutrients so that plants can grow well.
4. Irrigation – The field is watered from time to time to help the plants grow.
5. Protection – Fences are used to stop animals. Pesticides are sprayed to keep away harmful insects.
6. Harvesting and Storing – When crops are ready, they are cut. Grains are stored in godowns, and vegetables/fruits are quickly sent to the market.
5. What are the uses of seed coat and cotyledons in a seed? (5 marks)
Answer:
Seed Coat:
It is the outer hard layer of a seed.
It protects the seed from damage, dryness, and insects.
It keeps the baby plant safe inside until conditions are right for germination.
Cotyledons:
These are seed leaves present inside the seed.
They store food for the baby plant.
After germination, the plant uses this food until it grows real leaves and starts making food on its own.
So, both seed coat and cotyledons are very important for the life and safety of the baby plant.
