Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

5. Explain photorespiration and how the enzyme rubisco plays a major role in that process during photosynthesis?
false
pneumatophoves

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

transpiration
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

cassava
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

internodes
false
17. Plants whose leaves fall off at the end of the growing season are ___?
node
pericarp
horizon E
deciduous
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.
inferior
bracts
terger
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
19. What obvious characteristic does a deciduous plant exhibit?
venus flytrap - sundew trap - pitcher of a ptcher plant - tenri of a pea plant- all of the above
vascular bundles
vessel elements
grows back every year
20. The osmotic response of guard cells is governed by the ___ levels in the guard cells?
red light
diffusion is the movement of particles from high to low concentration; osmosis is movement of water from high to low concentration
stele
potassium
21. Stems differ from roots in ___?
water conduction
having a special covering called the root cap
vascular bundles
axillary bud and leaf
22. The skin of most fruits is technically the ___?
base of grass leaves
absorpion of minerals in solution
annual ring
exocarp
23. The best soil for plant growth is ___?
imbition
guard cells
loam
lose
24. Briefly describe the development of vascular tissu by the lateral/vascular cambium of a stem and how that results in the production of wood?
Irish (white) potato
sweet potato
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
