Which one of the following facilitates the transport of water, nutrients and allow upright growth in plants?
Correct answer: C. Primary cell wall
- A. None of these
- B. Both primary and secondary cell wall
- C. Primary cell wall
- D. Secondary cell wall
Explanation
The primary cell wall facilitates the transport of water, nutrients, and allows upright growth in plants. The primary cell wall is a relatively thin and flexible layer that surrounds plant cells. It is composed of cellulose, hemicellulose, and pectin, which provide structural support while allowing water and nutrients to pass through.The secondary cell wall, on the other hand, is a rigid and thick layer that forms inside the primary cell wall in certain plant cells, such as xylem cells. While the secondary cell wall provides additional strength and support to these specialized cells, it is not directly involved in the transport of water, nutrients, or upright growth in plants.Therefore, the correct answer is the primary cell wall.
