the cell attaching the guard cell
Answers
Answer:
Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. Light is the main trigger for the opening or closing. Each guard cell has a relatively thick cuticle on the pore-side and a thin one opposite it.

Answer:
Guard cells are specialized plant cells in the epidermis of leaves, stems and other organs that are used to control gas exchange.
They are produced in pairs with a gap between them that forms a stomatal pore.
The stomatal pores are largest when water is freely available and the guard cells turgid, and closed when water availability is critically low and the guard cells become flaccid.
Photosynthesis depends on the diffusion of carbon dioxide (CO2) from the air through the stomata into the mesophyll tissues.
