Seeds and Seeds Class 5 Notes: Environmental Studies Chapter 5 (Looking Around)

Summary of Seeds and Seeds

• The chapter Seeds & Seeds discusses many types of seeds as well as seed sprouting.

• It also explains how seeds move from one location to another.

• It also discusses the origins of numerous seeds from various locations that were later brought to India.

Seeds – A seed is a little embryonic (baby) plant that is surrounded by a seed coat. It develops as a result of seed plant reproduction. After germination, seeds develop into new plants.

Sprout – A sprout is a germinated seed with a growing stem and roots. It is eaten because it is very nutritious.

Now Let us Understand - How to Make Sprouts?

• Take some chana and moong in a bowl

• Fill the bowl halfway with water and leave it overnight.

• Drain out the water from the bowl the next day

• Tie the seeds in a wet cloth and hung them someplace

• Keep the cloth damp by making it wet regularly

• After 2 days you will see seed sprouts

What are the Conditions Needs to Follow to Make Sprouts?

• The production of sprouts requires both air and water.

• Seeds that have been soaked in water for an extended period of time will not sprout.

• They will not sprout if they are merely maintained in the air.

Plant Which Hunts – Pitcher Plant

• Insects, frogs, and even mice are caught and eaten by some plants.

• One such plant is the Pitcher Plant (Nepenthes), which can be found in Australia, Indonesia, and India's Meghalaya state.

• It has a pitcher-like shape, with a leaf covering its mouth.

• The plant emits a distinct odour that attracts insects.

• When an insect lands on the plant's mouth, it falls into the pitcher and is unable to escape.

Colour, Shape, and Texture of Seeds

Seeds come in a variety of sizes, hues, and textures. Different seeds, their hues, and textures are shown here. Allow us to clarify:

S.No.	Seeds Name	Colour	Shape	Texture
1	Rajma	Reddish-brown		Smooth
2	Papaya	Black +51		Rough
3	Mango	Whitish yellow		Rough
4	Moong	Green		Soft
5	Mustard	Green, black or yellow		Soft

Wandering Seeds (also known as Seed Dispersal)

Plants are unable to move. They are confined to a single location where they thrive, yet their seeds are extremely mobile. They have the ability to travel far and broad. The following procedures are used to transport seeds from one location to another:

• By Air - In the plant kingdom, the wind is the most natural and essential way of seed dispersion. This type of dissemination is most common in plants that produce very light seeds. Plants whose seeds are dispersed by the wind include orchid seeds, dandelions, swan plants, cottonwood trees, hornbeam, ash, cattail, puya, and willow herb seeds. 

• By Water - Seeds float away from their parent plant in this process of seed dissemination. These are mostly found in plants that dwell in or near water bodies, such as beaches, lakes, and ponds. Plants whose seeds are distributed by water include coconut, palm, mangroves, water lily, and water mint. 

• By Animals and Birds - Animals and birds disseminate their seeds in a number of different ways. Some are consumed by animals and expelled in the form of droppings, which sprout new plants. A few squirrel species harvest nuts from various plants, such as acorns, and bury them in the soil. There are a few plants that produce hook-shaped seeds. This type of plant is represented by the burdock plant. These plants' seed clings to the fur of animals and is taken away to other locations, far from their parent plants. 

The Idea of Making Velcro

• When George Mestral returned from a walk with his dog in 1948, he had the idea for Velcro. When he noticed seeds stuck to his clothes and his dog's fur, he was astounded.

• He watched the seeds to determine what made them stick. Seeds, he discovered, had several little hooks that adhered to clothing and fur.

• Mestral was inspired to create Velcro as a result of this. He created material with microscopic hooks that would adhere to the surface.

• Velcro is used to secure a variety of items such as clothing, shoes, bags, belts, and more.

Who Came From where?

Many fruits and vegetables that we cultivate or see around us were not grown in the past. They arrived in India from various countries. Here's a table with several common fruits and vegetables along with their origins:  

5 Important Topics of Class 5 EVS Chapter 5 Notes

Importance of EVS Chapter 5 Seeds and Seeds Class 5 Notes

• Explains how seeds grow into plants, detailing the different parts of a seed and the process of germination.

• Shows why seeds are important for producing new plants and their role in nature.

• Helps students learn about various types of seeds and their unique characteristics.

• Demonstrates how plants support ecosystems by helping other living things and maintaining balance in nature.

• Connects learning to real-life examples, making it easier to understand plant growth and its significance in everyday life.

Tips for Learning EVS Chapter 5 Seeds and Seeds Class 5 Notes

• Learn about the different parts of a seed, such as the seed coat, embryo, and cotyledons. Knowing their functions helps you understand how seeds grow.

• Familiarise yourself with various types of seeds and their characteristics to recognize different seeds and understand their uses.

• Watch the process of seed germination if possible. Observing seeds sprout and grow can make the concept clearer and more interesting.

• Draw or study diagrams of seed structure and germination stages. Visualising these processes helps in remembering the steps and parts involved.

• Relate what you learn to real-life examples, such as seeds you see in fruits and plants around you. 

• Understanding how they grow into new plants makes learning more practical and engaging.
