What is the role of guard cell?
Guard cells in epidermis around stomata pores helps in transpiration through stomata and exchange of gases.
Is leaf made of cells?
A typical leaf has an outer (epidermal) layer, pores (stomato) surrounded by a pair of guard cells, middle tissue (mesophyll) where photosynthesis occurs and a vascular system that carries water and nutrients.
How does gaseous exchange occur in the leaf?
There are cells called guard cells on the tiny pores (stomata) on the underside of a leaf. According to the status of the gases inside the leaf cells, and the outside conditions, the guard cells allow air into the pores. This brings in carbon dioxide and releases oxygen, but also releases water vapor. This transpiration process can be used to cool the leaf as needed.
Do all plants have guard cells?
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
What surrounds all cells?
All cells are surrounded by a semi-permeable cell membrane
What is the role of guard cell?
Guard cells in epidermis around stomata pores helps in transpiration through stomata and exchange of gases.
What are the cells the guard the stomata?
There are a large number of tiny pores called stomata on the surface of leaves of plants (The singular of stomata is stoma).Each stomatal pore (or stoma) is surrounded by a pair of guard cells .The opening & closing of stomatal pores are controlled by the guard cells.
Is a leaf made of a cells?
A typical leaf has an outer (epidermal) layer, pores (stomato) surrounded by a pair of guard cells, middle tissue (mesophyll) where photosynthesis occurs and a vascular system that carries water and nutrients.
Are guard cells part of the stomata or does stomata only refer to the pore on the lower surface of the leaf?
The stomata are the pores and the guard cells control the opening and closing of these pores.
What is the function of stomata and guard cells?
There are a large number of tiny pores called stomata on the surface of leaves of plants (The singular of stomata is stoma).Each stomatal pore (or stoma) is surrounded by a pair of guard cells .The opening & closing of stomatal pores are controlled by the guard cells.

What will an epidermis cell look like?
If it is a upper epidermal cell then it will looktransparentclose fittingrectangulara horizontal shapeThe upper epidermal cells are transparent and close fitting, containing no chloroplasts, which are present in other leaf cells. They allow light to pass straight through them. The epidermis is covered by a waterproof cuticle, which reduces water loss from the leaf, since it is a waxy substance.If it is a lower epidermis cell then it will look like cells covered in tiny pores (holes)The lower epidermis has tiny pores (holes)in it's surface called stomata.These are very important for the leaf to exchange gases with the air. The stomata pores can be opened or closed by special cells on either side of the pore called guard cells. thes sausage shaped ceel are green and are thae only epidermal cells to contain chloroplasts

What are the openings in the epidermis of a plant that allow air and water to pass in and out of the leaf?
Yes, the stomata, which are pores in the lower epidermis of the leaf and are surrounded by 2 guard cells, open in the day to let in CO2 for photosynthesis but they also release H2O as water vapour and they close at night to reduce water loss.
Do all plants have guard cells?
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
What is the openings in the epidermis of a leaf that let CO2 into the leaves?
The stoma, or pores of a plant control all gas exchange. The stoma is found in the epidermis of the leaf.
What cells guard the opening and closing of the stomata?
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.
