Stomata, which are holes in the epidermis of plants, allow for gas exchange and the passage or retention of water for the plant. Stomata enable respiration (gas exchange) in plants that provides for photosynthesis. Photosynthesis produces food for the plant from the transformation of oxygen from carbon dioxide, via the stomata as the pathway into the plant. Stomata also allows the passage of water into the plant (Transpiration), since the leaves are mostly covered by wax (the cuticle). Water can enter the vascular system, transporting nutrients and such to the rest of the plant. The stomata can also retain water in case of a shortage of water, like a drought, and prevent water loss, enabling the plant to survive longer.

Stomata are tiny holes on the bottom of a leaf. They open and close depending on the situations surrounding the plant. When the stomata are open, water is lost from the plant through evapotranspiration, which is when they evaporate from the surface of the leaf. The stomata close at a certain period of time in order to keep this water in. The stomata also open in order to let more carbon dioxide in, which is needed for photosynthesis. For example, if there is an increase in light around the plant, the stomata will open more often for photosynthesis, and will lose more water from the plant.

How do gases enter and leave plants?
In terrestrial plants, gas enters and leaves (termed "gas exchange") through cell-lined pores called "stomata." Stomata open and close in response to light and humidity, permitting oxygen, carbon dioxide and water vapor to enter and leave the plant. In most terrestrial plants, the stomata are located on the surface of the leaves, or in cacti, on the surface of the stems. In aquatic plants, gas exchange directly though the tissue surface.
How many stomata are likely to open at night?
In most green plants the stomata are only open during the day. They allow carbon dioxide to reach the cells where the majority of photosynthesis takes place. As they also allow transpiration (water loss) the stomata of most plants close during the night when photosynthesis is not possible. There is a group of mainly desert plants known as CAM plants. These carry out a process called Crassulacean acid metabolism, which effectively allows them to store carbon dioxide in their leaves. In these plants the stomata are normally closed during the day to prevent water loss when temperatures are high, and open during the night when temperatures are lower.
What gases that pass through the openings of leaves?
Oxygen comes out of the open stomata:)
3 What is the function of stomata in photosynthesis?
Stomata are tiny openings on leaves that act as mouths. They open and close to release and take in moisture.
. CAM plants close their during the day and open them at night?
stomata
What do leaves go through at night?
At night, the leaves of C3 plants close their stomata and wait until the sunlight. For CAM plants, this is when the plants open their stomata and allow the carbon dioxide to come in.
Through which structure do carbon dioxide and water enter plants?
stomata which are tiny spots on the underside of the leaf

Where does transpiration?
Transpiration is when water evaporates from plants. It occurs chiefly in the leaves while their stomata are open during photosynthesis.
What causes the stomata on leaves open?
Daylight
What causes the stomata on leaves to open?
Photosynthesis
The stomata of leaves are usually open in?
in the day
How do plants obtain the carbon dioxide they need for photosythesis?
through diffusion of air through the open stomata on the peripheri of leaves
CAM plants close their what during the day and open them at night?
Cam plants close during the night and open during the day because they are photosensitive and respond to light. To do it experimentally, try with a torch for some time.
What is the openings on leaves that let gases in and out of leaves are called?
Plants breath through stomates. they are microscopic openings covering the leaves that open and close bringing in CO2 and out oxygen. This gives us 29 percent of our oxygen while the other percentage (71) is from phytoplankton
Water vapor moves out of leaves through open stomata This process is known as?
Transpiration
Why don't plants keep their stomata open all time?
Plants don't keep their Stomata open all the time to prevent too much water loss.
