how does stoma open and close
When K+ ions move into guard cells beside epidermal cells, water moves with it by osmosis causing guard to swell, opening stomata When k+ ions move out guard cells, water follows by osmosis, causing guard cells to sag, closing stomata.
What percent of water loss is stomata responsible for
85% even though they only cover 1 to 2 percent of leaves
What is the stomatas role in photosynthesis
allow Co2 to diffuse when photosynthesis takes place for calvin cycle
what is transpiration pull
suction force that Pulls up the groundwater in an upwards direction. The Plant, for Photosynthesis, utilizes
What is the process called that flows water in and out the stomata
osmosis
What is the importance of the Stomata
stomata create a “transpiration pull” through water loss that draws water, minerals, and other key substances from the roots up to the leaves where they are used. Transpiration also provides a cooling effect that prevents leaves from heating to avoid denaturing Stomata also allow CO 2 to diffuse into the mesophyll where photosynthesis takes place.
