Gas released during photosynthesis:
- The gas released during photosynthesis is oxygen.
- Oxygen is evolved as a byproduct of the light-dependent reactions of photosynthesis.
Plants with closed stomata during the day:
- Certain groups of plants, such as CAM (Crassulacean Acid Metabolism) plants, keep their stomata closed during the day to reduce water loss.
- CAM plants perform photosynthesis at night when the stomata are open, and store the carbon dioxide in the form of organic acids.
- During the day, the stored carbon dioxide is released for use in the Calvin cycle, allowing the plants to carry out photosynthesis without losing excessive amounts of water.
Synthesis of food by plants with closed stomata:
- Despite having closed stomata during the day, CAM plants are still able to synthesize food.
- These plants use the stored carbon dioxide from the previous night's photosynthesis to carry out the Calvin cycle during the day.
- By utilizing the carbon dioxide stored in the form of organic acids, CAM plants are able to produce glucose and other carbohydrates for energy.
In conclusion, plants like CAM plants have evolved unique strategies to adapt to their environment and ensure efficient photosynthesis even with closed stomata during the day.
