Question

Some features of transportation in plants are mentioned below. Which option shows the INCORRECT feature?

• A. Movement of both water and food is bidirectional
• B. Water movement is by simple physical forces: food movement requires energy
• C. Xylem transports water and Phloem transports food
• D. Vessels and Tracheids are dead cells and Sieve tubes are living

Answer 1

Answer:

A. Movement of both water and food is bidirectional

• The statement 'Movement of both water and food is bidirectional' is incorrect.

• While some bidirectional movement might occur under specific conditions, the primary direction of water transport is upward (in xylem), and the primary direction of food transport is downward (in phloem)
