the root hairs on the root tips absorb water into the soil through osmosis. this water travels up the roots - up the stems - and to the leaves throughout the plant by capillary action. once absored in leaves - the water leaves the plant through trans
vessels
15. Specialized roots that permit plants growing in water to facilitate
transpiration rates can decrease

transpiration rates decrease
guard cell and root hair
imbibition
vascular bundles
17. Name the 4 parts of aflower and briefly explain the process of double fertilization?
exocarp
all of the above are correct
the sepal - petal - stamen - pistil are the 4 main parts. in double fertilization - the pollen grain produces 2 sperm cells which travel as pollen to the stigma and down the style ofthe pistil to the ovary. One will fertilize an egg in the ovary whil
grasslands
18. Which of the following is a micronutrient in terms of a plant's mineral requirements for growth?
red light
ovary
manganese
leave the cell
19. 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
major elements vegetation requires for growth (macronutrients)
tungor
fibrous
20. Why is visible light good energy to use for photsynthesis?

21. Which of the following drugs are NOT obtained from leaves?
digitalis
internode
grasslands
sweet potato
22. Which of the following is a specialized root?

sweet potato
region of maturation
pollen:stigma
23. When humidity is low - ___?
the presence of nodes and internodes
inferior
transpiration rates can decrease
parenchyma
24. Specialized epidermal cells that increase the surface area for absorption of water are ____?
vascular cambria
root hairs
pollen:stigma
lignin
25. The discrete paches of xylem and phloem found in herbaceous dicot stems are called ____?
phloem
h20+co@-->chlorophyl/light-->glucose (sugar) + o2
vascular bundles
bulb
26. The endodermis works to direct water through its cells by having the presence of a waxy layer of suberin called the ____ around its cells n only one plane?
