Question

How are pores beneficial to the plants

Answer 1

• Through these pores, plants uptake the carbon dioxide necessary for photosynthesis and release water by transpiration, which enhances uptake of nutrients from the roots. ... This triggers water uptake and cell swelling that opens the stomata.
• Stomata are the small pores in plant stems or leaves that allow carbon dioxide in and oxygen and water vapor out. Each tiny hole is surrounded by a pair of cells called guard cells. These cells control whether a stoma is open or closed.
