The guard cells synthesize glucose through photosynthesis in the presence of light. as glucose accumulates, osmotic pressure increases and this enables them to draw water from adjacent epidermal cells by osmosis. this makes the guard cells turgid and the stomata opens. at night, there is no photosynthesis and therefore glucose levels go down leading to lowering of osmotic pressure. guard cells lose turgidity and become flaccid and therefore stomata closes. Am sure you can derive your answer from this.
What else can I help you with?
How could you demonstrate which leaf structure regulates the amount of trandpirstion that occurs in a plant?
To demonstrate which leaf structure regulates transpiration, you can focus on the stomata, which are small openings on the leaf surface. By using a leaf with a clear epidermis or by employing a microscope, you can observe the stomata's movement in response to environmental conditions, such as light and humidity. Additionally, you could conduct an experiment by covering some stomata with clear nail polish to prevent transpiration and comparing the water loss of treated vs. untreated leaves. This would illustrate how stomatal density and opening regulate transpiration rates in plants.
What are small pores on the leaf surface called?
Small pores on the leaf surface are called stomata. They are responsible for regulating the exchange of gases, such as carbon dioxide and oxygen, during photosynthesis.
What do the stomata do for the leaf?
it gives the leaf food, carbon dioxide enters through tiny holes called stomata, Oxygen leaves plant through stomata. This is called respiration
What uses stomata as its route into the leaf?
Carbon dioxide uses stomata as its route into the leaf for photosynthesis. Stomata are small pores on the leaf surface that allow gas exchange, with carbon dioxide entering the leaf through these openings during photosynthesis.
Where on the leaf is the stomata found and how to prove that?
Stomata are found on the underside of plant leaves. To prove this, you can use a microscope to observe and identify the stomata on a leaf's underside. Staining techniques can also be employed to make the stomata more visible for identification.
What regulates the stomata?
The guard cells open and close the stomata as needed.

What is the size difference between the stomata in a crisp lettuce leaf and the stomata in a wilted lettuce leaf?
I believe stomata size will be the same after it enters the thylakoid memberane and wikapedia sucks because anyone can edit the information that is being given ight!!, it may appear small from wilt, stomata's vary in sizes from 100 to 1000 th of a millamitre in all plant species. If the stomata is reduced in size from wilt it will still function, maybe a fraction less that unwilted Lettuce. Regards Wayne Muller Barmac Industries Pty Ltd
Where are the stomata located on the lower surface of a leaf?
The stomata are located on the lower surface of a leaf.
How many stomata in a banana leaf?
more than a desert plant as the humidity and temperature allows for this
What is the small opening under a leaf called?
Stomata
Specialized structures that allow gas to enter and leave leaf?
Stomata
What part of the leaf transport air to the leaf?
stomata
How does carbon dioxide and oxygen enter and leave the leaf?
stomata
What does plant respires from?
plant respire through there leaf but from what i know that it could be stomata so it could be leaf or stomata..
What organelles do guard cells contain that are absent in the skin cells of a leaf?
Guard cells contain chloroplasts, which are responsible for photosynthesis, and a large central vacuole that regulates the opening and closing of stomata. These organelles are absent in the skin cells of a leaf.
Are stomata found in a leaves epidermis?
Yes, stomata are found in the lower epidermis of leaves in most plants. They are necessary for gas exchange, allowing the plant to take in carbon dioxide for photosynthesis and release oxygen and water vapor.
