18. Explain photorespiration and how the enzyme rubisco plays a major role in that process during photosynthesis?
having a special covering called the root cap
upper epidermal cells
photo respiration occurs usually in times of drought. limited water forces the plant to close stomata - therefore blocking co2. with lo concentrations of co2 and high concentrations of 02 - the enzyme rubisco starts to bind 02 instead of co2. this pr
grows back every year

22. In a mature - woody dicot stem - the tissue between the xylem and phloem is the ____?
it has node marks all over it where branches could grow off of.
cambium
mitochondria - chemiosmosis
into the cell
23. Because of greater light intensity and heat absorption on the upper surface of the leaf - the lower surface has ____?
antenna pigments
plasmolysis
more stomata on the upper surface
diffusion is the movement of particles from high to low concentration; osmosis is movement of water from high to low concentration
24. This tissue (region) is present in monocot roots but absent in dicot roots?
transpiration rates increase
vascular bundles
pith
fibrous
25. Flowers are usually attached to a special structure at the end of a stem or peduncle called a ___?
receptacle
traechids - vessel elements - companion cells - sieve-tube elements- all of the above
ovule
imbition
26. Which of the following drugs are NOT obtained from leaves?
mycoorhizae
K
digitalis
penetrate very deeply to underground water reservoirs

cortex
lose

glycolysis
upper epidermal cells
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
