You cut your initials in a tree 5 feet above the
ground this year. The tree grows 2 feet per
year and you return in 8 years. How high
are your initials at that time?
A. 5 feet
B. 10 feet
C. 16 feet
D. 21 feet
A. 5 feet
A tree grows from the apical meristem
at the top of the tree, not from the
bottom. Therefore, the initials do not
move from their original spot.
Which of the following are long, thin cells
that overlap, are tapered end to end, and
carry water?
A. Parenchyma
B. Sieve tube members
C. Tracheids
D. Companion cells
C. Trachieds
Which of the following occurs after
fertilization?
A.The ovule becomes the seed
B.The ovary becomes the seed
C.The micrpoyle becomes the seed
D.The stigma becomes the seed
A.The ovule becomes the seed
After, fertilization the ovule becomes
the seed and the ovary becomes the
fruit. None of the other choices make
sense
In plants, the transfer of male
gametophytes from place to place is
called____, while the fusion of a sperm
and egg is called ____?
A. fertilization/fertilization
B. fertilization/pollination
C. pollination/pollination
D. pollination/fertilization
E. pollination and fertilization are the
same
D.
pollination/fertilization
Which of the following is specifically
adapted for the dissemination of seeds?

of water and minerals into the vascular
cylinder of a root?
A. Cortex
B. Casparian Strip
C. Tracheids
D. Companion cells

exits, and the stoma closes
D. Potassium is passively transported into the guard cell, water
enters, and the stoma opens
E. Potassium is actively transported into the guard cell, water
follows, and the stoma opens
E. Potassium is actively
