22. Explain how a guard cell opens and closes the stoma?
pith
compound - simple
major elements vegetation requires for growth (macronutrients)
to open - potassium will enter the guard cell. then the guard cell will swell and attract water to the stomata - or area of high concentration. Once the plant has enough water - potassium will diffuse out - the guard cells will shrink - and finally c
23. Stems differ from roots in ___?
vascular bundles
vessels
having a special covering called the root cap
pericarp
24. Which of the following is a root with a specialized function for food storage?
cambium
pressure-flow hypothesis
pericarp
sweet potato
25. The part of the flower in which seeds are produced is the ___?
tap - fiblous
stele
ovary
taproots
26. Which cell types hav the primary function of photosynthesis?
fruit
3 carbon pathway
chollenchyma
plasmolysis
27. Root hairs are found in the region of the root called the ____?
region of maturation
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
oxygen
imbition
28. Why do most roots tend to die in soils that contain very high concentrations of salts (or fertilizer)?
it has node marks all over it where branches could grow off of.
vascular bundles
transpiration rates increase
If there is a higher concentration of salts outside of the root - then water will not move inside the roots against the concentration gradient. the roots will dehydrate and eventually die
29. This tissue/region is present in monocot roots but absent in dicot roots?
pith
major elements vegetation requires for growth (macronutrients)
all of the above are correct
annual ring
30. Cells produced by the vascular cambium do NOT include ___?
transpiration rates can decrease
it has node marks all over it where branches could grow off of.
cotyledon
phelloderm
31. The part of the flower where seeds are produced is called the ___?
upper epidermal cells
receptacle
penetrate very deeply to underground water reservoirs
ovary
32. A farmer finds that his landin the wetbottoms during an exceptionally wet year produced a very poor crop as most of the plants died. What could've been the problem?

33. You have a crop that is not doing well and you add a lot of fertilizer to help it out but this causes the crop to do worse. ExplaIn what has happened?
auxillary
