Seeds and Seeds Class 5 Chapter Notes

Introduction

The chapter “Seeds and Seeds” is about different types of seeds, seed sprouting. It also describes how seeds travel from one place to another. It also tells us about some seeds of different vegetables that came to India from different countries.

What is Seed

A seed is a small embryonic (baby) plant enclosed in a covering called seed coat. It is formed as part of reproduction in seed plants. Seeds grow into a new plant after germination.

Why do seeds swell up on soaking?

Seeds swell up when we soak them in water because water enters the seeds and it makes them swell up.

What is a sprout?

A sprout is a germinated seed in which the stem and root have come out. It is nutritious so is used for eating.

How to make sprouts

1. Take some chana or moong in a bowl.
2. Fill the bowl with water and keep the bowl overnight.
3. Drain out the water from the bowl the next day.
4. Tie the seeds in a wet cloth and hung them someplace.
5. Keep the cloth damp by making it wet regularly.
6. After 2 days you will see seed sprouts.

Conditions Necessary to make Sprouts.

• Both water and air are necessary for the formation of sprouts.
• If seeds are kept soaked in water they will not sprout.
• If they are kept in the air only, they will not sprout.

Plants Which Hunt

• Some plants trap and eat insects, frogs and even mice.
• The Pitcher plant (Nepenthes) is one such plant.
• It is found in Australia, Indonesia and Meghalaya in India.
• It has a pitcher like a shape and its mouth is covered with a leaf.
• The plant has a special smell that attracts insects.
• When an insect lands on the mouth of the plant, it slips into the pitcher and cannot get out.

Colour, Shape and Texture of Seeds

Seeds have different shapes, colours and textures. Here are different seeds, their colours and their textures.

Wandering Seeds.

Plants cannot move they are fixed at one place where they grow but their seeds are great travellers. They can reach far and wide. The seeds travel from one place to another by following methods.

1. By Air.
2. By Water.
3. By Animals and Birds

The idea of Making Velcro

The idea of making Velcro came in 1948 when George Mestral came back from a walk with his dog. He was amazed when he saw seeds sticking all over his clothes and his dog’s fur. He wondered what made these seeds stick and observed them. He found that seeds had many small hooks which stuck to clothes or fur. This gave Mestral an idea of making Velcro. He made material with tiny hooks that would stick. Velcro is used to stick together many things like clothes, shoes, bags, belts and many more.

Who came from where?

There are so many fruits and vegetables that we grow or see around us that were not grown in past. They came to India from different countries. Here is a table which shows some common fruits and vegetables and where they came from.
