Plant Structure and Function Concepts

The video tutorial covers the main parts of plants: roots, stems, and leaves. It explains the function of roots in absorbing water and nutrients, the role of xylem and phloem in transporting water and food, and the importance of leaves and stomata in photosynthesis and gas exchange.

What are the three main parts of a plant discussed in the video?

• Roots, stems, and leaves

• Flowers, fruits, and seeds

• Bark, branches, and roots

• Leaves, flowers, and fruits

What is the primary function of root hairs?

• To protect the root

• To produce food

• To absorb water and nutrients

• To support the plant

Which part of the plant is responsible for transporting water?

• Stomata

• Xylem

• Chloroplasts

• Phloem

Where does photosynthesis primarily occur in a plant?

• Roots

• Stems

• Flowers

• Leaves

What is the main role of phloem in plants?

• Photosynthesis

• Transporting water

• Gas exchange

• Transporting food

What can happen if the phloem of a tree is damaged?

• The tree will become shorter

• The tree will produce more leaves

• The tree may die

• The tree will grow faster

What is the function of stomata in leaves?

• To exchange gases

• To produce seeds

• To store water

• To absorb sunlight

How do plants control water loss through stomata?

• By opening more stomata

• By growing more leaves

• By increasing photosynthesis

• By closing guard cells

What gas enters the leaf through the stomata for photosynthesis?

• Hydrogen

• Oxygen

• Nitrogen

• Carbon dioxide

What happens to oxygen produced during photosynthesis?

• It is released through the stomata

• It is absorbed by the soil

• It is stored in the roots

• It is used to make food
