Describe the difference between taproot and fibrous root systems.

Taproot systems have a single, thick main root (primary root) that grows deep into the soil, with smaller secondary roots branching out.

Fibrous root systems consist of many thin, branching roots that grow from the base of the stem, spreading out in various directions.

Taproots are seen in plants like mango and carrots, while fibrous roots are seen in grass and wheat.

Explain the functions of the stem in a plant.

The stem provides support to the plant, holding up its branches, leaves, flowers, and fruits.

It acts as a transport system, carrying water and nutrients from the roots to other parts of the plant and food from the leaves.

In some plants, like potatoes and sugarcane, the stem also stores food.

What are the main parts of a leaf, and what are their functions?

The leaf blade (lamina) is the flat, green part that absorbs sunlight for photosynthesis.

The midrib is the central vein that provides support and transports materials.

The petiole attaches the leaf to the stem.

Stomata are tiny openings on the underside for gas exchange and water vapor release.

Describe the process of photosynthesis.

Photosynthesis is the process by which plants make their own food using sunlight, water, and carbon dioxide.1

Chlorophyll, the green pigment in leaves, traps sunlight energy.

Plants take in water from the soil through their roots and carbon dioxide from the air through stomata.

They convert these into glucose (food) and oxygen, releasing oxygen into the atmosphere.

Explain the process of transpiration and its importance.

Transpiration is the process by which plants release excess water vapor from their leaves through the stomata.

It helps to cool the plant, preventing it from overheating.

Transpiration also plays a crucial role in the water cycle by adding water vapor to the atmosphere.

It also helps in the transportation of nutrients from the roots to the leaves.

List some products we get from plants and their uses.

We get food like fruits, vegetables, and cereals from plants.

Fibers like cotton and jute are used to make clothes and ropes.

Wood from trees is used for furniture and construction.

Medicines like quinine and aloe vera are obtained from plants.

What are the uses of Banana Plant?

Raw banana is cooked and eaten as a vegetable.

Ripe banana is consumed as a fruit.

Banana leaves are used as plates for eating.

Fibers from the stems of the banana plant are used for making useful items.

What are the uses of Coconut Plant?

The Coconut fruit is used in cooking.

Coir fiber from coconut is used to make ropes and mats.

Coconut oil is used in cooking and cosmetics.

Coconut leaves are used to make roofs.

Why leaves are called food factory of plants?

Leaves are the primary site of photosynthesis.

They contain chlorophyll, which traps sunlight.

Leaves use this energy to convert water and carbon dioxide into glucose (food).

This food is then transported to other parts of the plant.

What is the importance of root in plants?

Roots anchor the plant firmly in the soil, preventing it from being blown away.

They absorb water and essential nutrients from the soil, which are vital for plant growth.

Some roots store food, providing energy for the plant.

Roots also help prevent soil erosion.
