Stomata are microscopic holes in a plant leaf These holes are
located on the underside of the leaf
Slide 4
The stomata are the openings
Slide 5
Stomata allow gases such as CO2 and oxygen to enter and leave
the plant Additionally, these structures regulate the movement of
water in and out of the leaf
Slide 6
Slide 7
Plants need to take in CO2 for the process of photosynthesis
Additionally, plants need to regulate water loss Plants that do not
keep enough water in their cells wilt and die
Slide 8
Slide 9
Slide 10
Guard cells are the cells located around the stoma of the plant
leaves
Slide 11
The guard cells are the two flaps that surround the stoma
Slide 12
Guard cells regulate the opening and closing of the
stomata
Slide 13
Guard cells help control how much CO2 and water will enter the
leaf These are both key ingredients for photosynthesis to occur
They also allow oxygen to exit Lastly, the guard cells help
maintain water homeostasis Guard cells will close when water is
limited
