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?
sieve tubes and guard cells
✓
apical meristem and lateral meristem
✓
3.
Secondary growth is produced mainly by the
4.
Which of the following is not involved in the light reactions of photosynthesis
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
✓
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
✓
lose the ability to take in minerals
✓
loss of too much oxygen
✓
7.
Which of the following is an example of parenchyma cells?
8.
Which type of cell makes up xylem?
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?
11.
Which two factors are most essential for plant survival?
carbon dioxide and temperature
✓
water and carbon dioxide
✓
12.
Which inorganic compound is actively pumped through the plant to aid osmosis?
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
✓

✓
16.
