Question

Hard time understanding this unit

Answer 1

2. To transport water to the entire plant, especially the leaves where photosynthesis takes place. This is important because water is required for photosynthesis to take place.

3. Chlorophyll.

4. The palisade layer contains the most chloroplasts.

5. The function of the stomata is to allow gas exchange to facilitate photosynthesis. It also controls the rate of photosynthesis to regulate water use of the plant. Without it, plant would have severely hindered transpiration, causing the plant to die.

6. Chloroplasts are where photosynthesis takes place. Without chloroplasts, no synthesis would happen.

7. A leaf from a desert plant would likely have less stomata to conserve water content in the plant from evaporation due to environmental factors. This is because water escapes to the environment when stomata are open in plants. The contrary would be the case for plants in a tropical environment where water is more abundant and sunlight is more lacking.
