If the temperature is not very hot when would stomata generally be open or closed?
Stomata are generally open during the day when light is available for photosynthesis and closed at night to conserve water and prevent excessive transpiration. If the temperature is not very hot, stomata may remain open longer during the day to allow for increased gas exchange for photosynthesis.
Which physiological adaptation would decrease the process of transportation in a plant?
Closing stomata would decrease the process of transportation in a plant by limiting the exchange of gases (such as carbon dioxide and oxygen) and water vapor with the environment. This would reduce transpiration and nutrient uptake.
Would the stomata open or close if the CO2 concentration decrease?
Opening and closing of stomata is regulated by concentration of water in guard cells. When transpiration is required, water reaches the guard cells and they swell up. This opens the stomata's pore. When they are not required to be opened, water is not present in guard cells and they shrink causing stomata's pore to close.
Why would it be an advantage for a plant to have stomata on the underside of a horizontal leaf?
Having stomata on the underside of a horizontal leaf can reduce water loss through evaporation because the stomata are shaded from direct sunlight and wind. This positioning also helps minimize the risk of damage to the stomata from environmental factors.
Why does duckweed have stomata on the top surface of the leaf?
Duckweed has stomata on the top surface of the leaf to minimize water loss and prevent desiccation. By having stomata on the upper surface, duckweed can control gas exchange while reducing exposure to dry and windy conditions.
What part of the day would the stomata be closed?
midday
What do you think would happen if a plant had no stomata?
If a plant did not have stomata on the bottom of its leaves, water and oxygen leaving the plant would not be regulated.
Why would the stomata be in particular be effected if a plant is not watered?
as the stomata is responsible in gas exchange, and it constantly looses water through it the stomata would die out

What structure would control the exchange of these gases in a plant?
stomata

Closing stomata would decrease the process of transportation in a plant by limiting the exchange of gases (such as carbon dioxide and oxygen) and water vapor with the environment. This would reduce transpiration and nutrient uptake.
When would plant cells need to close or partially close their stomata?
Plant cells would need to close or partially close their stomata during times of water stress, such as drought, to prevent excessive water loss through transpiration. Closing the stomata also helps conserve water by reducing the entry of harmful pathogens or pollutants into the plant.
What structure would control the exchange in theses gases in a plant?
The following is a characteristic of monocots are stomata.
What would happen if a plant lacks stomata?
Water could not pass through it and it could not function.
What would happen to plant if its stomata stayed open all the time?
It would dehydrate because it would transpire too much.
