To complete the chart regarding the conditions under which stomata open or close to regulate gas exchange, here's how it generally works:
-
Daytime:
- Stomata Open: During the day, stomata typically open to allow for gas exchange (CO2 in, O2 out) for photosynthesis.
-
Nighttime:
- Stomata Closed: Stomata usually close at night because there is no sunlight for photosynthesis, and plants lose water through transpiration if they are open.
-
Carbon Dioxide Needed:
- Stomata Open: Stomata open to take in CO2 for photosynthesis during daylight.
-
Oxygen Produced by Photosynthesis:
- Stomata Open: Stomata are open to release oxygen produced during photosynthesis.
-
Hot Daytime Temperatures:
- Stomata Close: In very hot conditions, stomata may close to prevent excessive water loss through transpiration, even during the day.
Based on these explanations, here’s how you can complete the chart:
- A Daytime: Stomata Open
- B Nighttime: Stomata Closed
- C Carbon Dioxide Needed: Stomata Open
- D Oxygen Produced by Photosynthesis: Stomata Open
- E Hot Daytime Temperatures: Stomata Closed
