Document Summary

Protected by guard cells allowing water to flow. Seals to keep moisture on hot day for example. Guard cells are swollen due to high concentration of water inside, less water outside, and the water is escaping. The cell is full of water so it s full and closes the stoma. Gives off oxygen and has empty space to store oxygen. Stolon: stems horizontally above ground, nodes drop down to touch the ground to absorb water. (net-like roots with large parts, potatoes) Rhizome: underground horizontal stems that are long and thin (long carrot like) Turgor: water filled pith and cortex will expand the stems and supports the plants. Order: zone of maturation > zone of elongation > meristematic region > root cap. Epidermis: layer of cells without chloroplasts to protect and absorb liquids. Root hairs: protection and increase surface area for absorption. Cortex: bulk amount of cells that stores nutrients with large vacuoles. Endodermis: uniform linked cells around the inner bundle.
