1. Which of the following statements is correct?
Plant cells divide by mitosis in all regions of the root.
Two examples of meristem tissue are apical and lateral (pericycle)
The meristem tissue is found only in the root.
The meristem causes the roots cells to perform meiosis
2. In all vascular plants (tracheophytes), what are the names of the two general types of vascular tissue?
vessels and stomata
sieve tubes and guard cells
xylem and phloem
apical meristem and lateral meristem
3. Secondary growth is produced mainly by the
epidermis
ground tissue
vascular tissue
vascular cambium
4. Which of the following is not involved in the light reactions of photosynthesis
NADPH
water
ATP
CO2
5. When the stomata are open they allow carbon dioxide to enter, but they also allow
for photosynthesis to continue in the dark
for nitrates to leave the leaf
insects to enter and pollenate
for the loss of water
6. If a plant's leaves lost their cuticle through the action of an air pollutant, the major danger to the plant is;
gains too much moisture
loss of moisture
lose the ability to take in minerals
loss of too much oxygen
7. Which of the following is an example of parenchyma cells?
mesophyll
cortex
pith
all of these
8. Which type of cell makes up xylem?
parenchyma
collenchyma
sclerenchyma
sieve tubes
9. The vascular bundles of dicots are located:
scattered through the stem
up through the middle of the stem in one long thin slice
arranged in a ring inside the cortex of the stem
in the epidermal layer in roots
10. What plant hormone that regulates growth is "killed" by light (which allows it to grow towards the light) is?
ethylene
gibberellins
cytokine
auxin
11. Which two factors are most essential for plant survival?
water and oxygen
temperature and oxygen
carbon dioxide and temperature
water and carbon dioxide
12. Which inorganic compound is actively pumped through the plant to aid osmosis?
Potassium
Carbon Dioxide
Water
Chlorophyll
13. Which of the following statements about osmosis is true?
When ions (Potassium) are pumped into a cell, water reacts by leaving the cell
Osmotic pressure is so strong that water can get pushed 40m up a tree by a single ion
A major setback with using osmosis is that it does not require energy (ATP)
Water flows from hight to low concentration because ions (Potassium) are pumped first
14. Xerophytic plants have what adaptations in their leaves to allow them to survive?
stomata on the surface
a thin waxy cuticle
dermal pits and hairs
large air spaces in their spongy mesophyll
15. The primary function of leaves includes all EXCEPT
primary photosynthetic organ
increase SA and light exposure
store photosynthetic products
control water loss and gas exchange
16. Which of the following is NOT a primary function of the stem?
primary site of photosynthesis
transport water and nutrients
support the leaves and expose them to the sun
display of reproductive structures(i.e.. flower)
17. What are the openings in the leaves of plants that permit the exchange of gasses called?
xylem
stomata
plasmodismata
stroma
