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
✓
