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.
Guard cells, which control the opening and closing of the stomata (minute openings in the leaf that allow exchange of gases and exit of water vapour from the leaf) are located mostly on the underside of a leaf, with some being on the upper suface of the leaf.
Guard cells are paired cells that surround the stomata (one pair each) of plants on the epidermis of the plant's leaves. Stomata are openings in the leaf allowing the exchange of gases between the plant and its environment. These cells regulate which gases enter and which gases leave the plant, e.g. CO2 enters, O2 and water vapor are released.
Guard cells are located on the bottom of leaves on either side of a stomatal opening.
A guard cell is situated near the stomata of a leaf.
if you are refering to Biology, a guard cell is a eucariotic cell, which includes a nucleous, mitochondria, and cytoplasm
the stomata are on the leaves and stem(s). guard cells are on the stomata openings
they pretect the leaves.

Stomatal pores in plants regulate the amount of water and solutes within them by opening and closing their guard cells using osmotic pressure. Guard cells and adjacent subsidiary cells are involved in opening and closing of stomata.
These are called the guard cells.
The guard cells controll the opening and closing of the statoma!

the function of guard cells are that they control the opening and closing of the stoma

No Guard cells are cells that close when there is dry weather, preventing the leaf from becoming dehydrated

yes all plants have guard cells because if there's a plant that don't have guard cells the stomatal pores will not open neither close
The stomata are controlled by two epidermal cells called guard cells. When water flows in, the guard cells swell up and closes the stomata. When the water leaves, it becomes flaccid and opens the stomata.
Answer1. Guard cells have chloroplast, epidermal cells do not have.2. Guard cells are much smaller than the epidermal cells.3. The cell walls of guard cells are not uniform, inner walls are thicker than the outer walls. epidermal cells are unformly thin.
