Do guard cells open during the day to allow gases to flow through the stomata?
Yes this is true.
What is the chemical difference between stroma and the cytoplasm?
A "stoma" is singular, whereas "stomata" is plural. Each guard cell is surrounded by two guard cells which are specialized parenchyma cells. Imagine that the guard cells are like two longish, curved balloons tied together at each end. (Each guard cell is like one of these balloons). If the balloons are both filled with air, they curve away from each other, creating a hole in the middle (a stoma). However, if the two balloons are not filled with air, they are pressed tightly together. (Guard cells are pressed tightly together by the surrounding parenchyma cells). During the day, sunlight causes the chloroplasts within the guard cells to produce sugar. (Guard cells contain more chloroplasts than surrounding parenchyma cells). Sugar builds up within the guard cells. By osmosis, water is drawn into the guard cells from the surrounding parenchyma cells, causing the guard cells to swell and close the stomata. This prevents water loss from the leaf during the heat of the day. At night, the sugar is used up, the water within the guard cells passes out of the guard cells, and the stomata open for transpiration and gas exchange: Carbon dioxide, oxygen and water vapour pass in and out of the leaves through the stomata. (Most stomata are found on the leaves of most plants, though cactus have them on their stems - because the leaves of cactus are the needles).
What happens when stomata opens?
Carbon dioxide, Oxygen, water vapor, and other gases enter and exit the stoma. They open during the day because plants need to take in raw materials (Such as the three listed at the beginning of the answer) to make food.
What is the most likely affect on the plant if the guard cells stay swollen on a hot day?
Increase intherate of transpiration
What plants close stoma to control transpiration?
All plants use guard cells to control how long stomata should be opened or closed. CAM plants, for example, close their stomata during the day to prevent loss of water.
Do guard cells open during the day to allow gases to flow through the stomata?
Yes this is true.
How is the opening and closing of stomata controlled?
The guard cells controll the opening and closing of the statoma!
How do Sumatran tigers behave?
thet eat and sleep during the day and hunt during the night.

What guard cells guard?
They are the pair of cells that surround the stomata (pores on the underside of leaves) They can change shape to open or close the stomata. Most plants open their stomata during the day (to allow co2 to enter for photosysthis) and close them at night. However cacti open their stomata during the night to reduce water loss, and have to use stored co2 for photosysthesis.
What plants close stoma to control transpiration?
All plants use guard cells to control how long stomata should be opened or closed. CAM plants, for example, close their stomata during the day to prevent loss of water.
How do normal leopards behave?
leopards behave differently than most wild cats. They are lonely creatures, only coming together to mate. They are nocturnal and during the day, hide in big trees and sleep.
What do guard cells in a plant do?
The guard cells in a plant are responsible for opening and closing the stomata. The stomata is a tiny opening on the blade of a leaf that allows for carbon dioxide to enter and water + oxygen to be released. The guard cells are triggered by concentrations of potassium ions.
What is the function of the stomata opening?
The stomata in the surface of a plant open during daylight (for most plants) and allow CO2 to be absorbed and O2 released. These gases just diffuse to and from the air via the stomata, but are reacted within the interior of the plant. [Some desert plants have their stomata closed during the day, to conserve water. They open their stomata at night, and store CO2 in a special chemical, then close the stomata during the day, but still use the sunlight to convert the CO2 into sugars and starches.]
Why do cells make more oygen during the day than the night?
energy
