18. When a plant is fully saturated with water it is said to be high in ___ pressure wheras if it is low in water the plant is said to be flacid.
The cambium is a ring of undifferentiated cells. Once a cell moves to the outside of the cambium it becomes phloem. When the cells move into the inside of the cambium - the cells become xylem. Xylem cells die - harden and begin expanding with fresh x

compound - simple
terger
19. The skin of most fruits is technically the ___?
dioecious; staminate
guard cells

20. Because of greater light intensity and heat absorption on the upper surface of the leaf - the lower surface has ____?
more stomata on the upper surface

23. Which biome has the best 'A' horizon?
phloem
grasslands

cellulose
24. Specialized roots that permit plants growing in water to facilitate
stigma
pneumatophoves
visible light is good because it's not as intense so that it will burn the plant - but it is still intense enough to produce plenty of energy
