4. A structure not present in a plant cell is the:
(A) basal body
(B) cell membrane
(C) centriole
(D) Golgi complex
(E) mitochondrion
next
c
0
5
Correct.
next
wrong answer explanation
5
(C) The spindle is anchored in animal cells by the centrioles; plant
spindles lack these anchors.

(C) cilium
(D) chromosome
(E) cytoplasm
next
b
0
7
Correct.
next
wrong answer explanation
7
(B) The cell membrane next to a pore can take in liquids by surrounding
them, a process called pinocytosis.

7. Which of the following doubles its number during interphase?
(A) cell vacuole
(B) centriole
(C) chromosomes
(D) Golgi complex
(E) cell membrane
next
c
0
8
Correct.
next
wrong answer explanation
8
(C) In preparation for the next cell division, the number of chromosomes
doubles during interphase.

(A) nuclear membrane
(B) lysosome
(C) centriole
(D) mitochondria
(E) nucleolus
next
d
0
B
Correct.
next
wrong answer explanation

(D) lysosome
(E) centriole
next
a
0
3
Correct.
next
wrong answer explanation
3
(A) Cilia are often lacking in animal cells.

(A) bacteria
(B) blue-green algae
(C) ciliated protozoa
(D) fungi
(E) mosses
next
b
0
4
Correct.
next
wrong answer explanation
4
(B) Blue-green algae may have been the first photosynthetic cells and have
no sexual reproduction.

(D) phytochrome
(E) auxin
next
e
0
5
Correct.
next
wrong answer explanation
5
(E) Phototropism, the movement of a plant toward light, is caused by
auxin, a hormone that stimulates growth on the side of the plant AWAY
from the light, causing the plant to bend toward the light.
