photosynthesis and food transport
Which system interactions are dependent on the plant's ability to respond to the direction of light?
Q
Option 2
Option 4
Option 3
Option 1

Answer 1

The plant's ability to respond to the direction of light is primarily related to the shoot system, as shoots typically grow toward light sources to maximize photosynthesis.

In the options provided:

- **Option 2:** Shoot - seed dispersal and absorption of CO2
- **Option 4:** Shoot - photosynthesis and food transport
- **Option 3:** Root - respiration and food storage
- **Option 1:** Root - absorption of water and nutrients

Among these, **Option 4** (which includes photosynthesis, a process that is influenced by light direction) is directly related to the plant's ability to respond to the direction of light.

Therefore, the answer is **Option 4**.
