How are the opening and stomata related to transpiration When does transpiration occur?
opening and closing of stomata occurs due to turgor changes in guard cells ....................due to exchange of gases carbon dioxide accumulate creating acidic nature resulting in favourable conditions for conversion of starch to glucose ...........glucose being soluble in water increases solute content resulting in endosmosis ..................this results in pulling apart of the opposed inner thicker walls creating an open pore in gaurd cells of stomata
What else can I help you with?
What happens to the appearance of the guard cells when the stomata are open?
It absorbs water and forms an arc, the outer layer thins as water is absorbed.
Where does most transpiration occur in a leaf?
On the bottom of the leaves. This is because Stomata, the place in the leaf were gaseous exchanges of water and carbon dioxide occur, are more common in this part of the leaf compared to the top of the leaf. This is an adaption, because if plants had all of their stomata on the top of their leaves, excessive loss of water will be lost to the environment and cause dehydration of the plant and even potential death.
Why transpiration does not takes place at night?
Transpiration does not occur at night because the stomata (small openings on leaves that allow for gas exchange) typically close in the absence of sunlight. The closure of stomata helps to conserve water and prevent excessive water loss from the plant when there is no light available for photosynthesis.
Why does the stomata of a plant open after the plant has been watered?
When a plant is watered, it creates a turgor pressure in its cells, causing the guard cells surrounding the stomata to swell and open. This allows for gas exchange to occur, such as the intake of carbon dioxide for photosynthesis. Opening the stomata also helps regulate the plant's internal water balance.
What happens when the stomata opens?
When the stomata open, it allows for gas exchange to occur in plants. Carbon dioxide enters the leaf for photosynthesis while oxygen and water vapor are released. This process helps with photosynthesis and transpiration.
Where does gas exchange and water loss occur in plants?
By opening and closing the stomata on the underside of the leaves.

What is the function of stomata in a leaf?
Stomata are small pores in the underside of leaves. The primary function is to allow gaseous exchange between the plant's internal tissues and the atmosphere. Oxygen and water vapour (byproducts of photosynthesis) are released from the open stomata into the atmosphere; carbon dioxide present in the atmosphere is allowed to enter the stoma (this is required for photosynthesis.
What is the main cause of transpiration?
the main cause of transpiration in plants is because transpiration means loss or gain of water in plants or give off water vapour from the leaves which is necessary for the process of photosynthesis
The pineapple plant closes its stomata during the day and opens its stomata during the night. This process helps the plant conserve water by preventing?
transpiration.
Is water loss in plants greater during the day or at night?
Water loss in plants is typically greater during the day due to the process of transpiration, where water is lost through the stomata on the leaves. This is because transpiration rates are usually higher when the stomata are open for photosynthesis to occur. At night, when photosynthesis does not take place, transpiration rates are lower.
How stomata occur during night?
Stomata do not occur - during the night or day. Stomata are physical features of leaves: they are there from when the leaf is created to when it dies.
How light intensity affects transpiration?
light, along with carbon dioxide and water allows photosynthesis to happen, producing glucose and oxygen. therefore, the glucose created may allow the plant to transpire? so im thinking the light along with carbon dioxe and water equally affects the activity of transpiration, using the energy made by photosynthesis. i may not be correct as im year10, and i just briefly read the definition of transpiration, but that's what i think. EDIT: College student Carbon dioxide and light are necessary for photosynthesis to occur. Plants have specialized structures known as stomata, essentially tiny little mouths, that open up in order to allow carbon dioxide to enter the plant. The problem is, plants also really need water, and when stomata are open, water leaks out the tiny little holes. It wouldn't be very efficient to keep the stomata open all the time, as the plant would constantly be losing water. For that reason, plants only open their stomata when all the conditions are right for photosynthesis. If light and CO2 are missing, the stomata stay closed and the plant gets to keep its water. If light and CO2 are present, the stomata open and photosynthesis begins. Transpiration is defined by water loss through the leaves of a plant, so it makes sense that it would go way up when the stomata are open. Transpiration rate increases with light intensity.
