Structure and Function of Living organisms: Absorption and Transmission of Water and Mineral Salts in Plants:

The video tutorial explains the process of water and mineral absorption and transmission in plants. It begins with the root system's role in absorbing water and mineral salts, detailing the structure and function of root hairs, epidermis, cortex, endodermis, xylem, and pith. The transmission process is described in three steps, highlighting the movement from root hairs to the xylem and then to the stem and other plant parts. Finally, the video covers the transpiration process, where plants release excess water through stomata openings.

What is the primary function of root hairs in the plant's root system?

• To store energy for the plant

• To transport nutrients to the leaves

• To absorb water and mineral salts

• To support the plant structurally

Which layer regulates the passage of water to the xylem?

• Pith

• Endodermis

• Cortex

• Epidermis

What role does the xylem play in the plant?

• It stores nutrients

• It transports water and minerals to the stem and leaves

• It absorbs sunlight for photosynthesis

• It protects the plant from pests

How does the plant get rid of excess water?

• Through the root hairs

• By storing it in the stem

• By converting it into energy

• Through the transpiration process via stomata

What is the function of stomata in the transpiration process?

• To capture sunlight

• To expel excess water

• To release oxygen

• To absorb carbon dioxide
