1. Specify the similarities and differences between plant and animal cells:
Similarities: a. _______________________________ b.
_______________________________ c.
_______________________________
Differences
Plant cells Animal cells
3. . Classify the following under the headings 'Cell structure', 'Tissue', 'Organ' or 'System'.
bone, nucleus, skeleton, brain, nerve, mitochondrion, muscle, cytoplasm, epithelium,
heart and blood vessels, stomach, alimentary canal, lung, lungs and windpipe
4.
The control center or brain of the cell is the
A. Nucleus
B. Mitochondria
C. Cell membrane
D. Endoplasmic reticulum
5.
The main function of the cell wall is to
A. Support and protect the cell
B. Store DNA
C. Help the cell move
D. Direct the activities of the cell
6.
Diffusion of water is
A. Facilitated diffusion
B. Active transport
C. Osmosis
D. Exocytosis
7.
This is the jelly-like substance found in all cells:
A. Centrioles
B. Cytoskeleton
C. Chromosomes
D. Cytoplasm
8.
This is considered to be the opposite of diffusion because it moves molecules from an area of low concentration to high concentration. the cell must use energy to make this happen.
A. Diffusion
B. Osmosis
C. Active transport
D. Facilitated diffusion
9.
Which of the following is not found in an animal cell?
A. Large central vacuole
B. Cell wall
C. Chloroplast
D. Chlorophyll
10. What is wrong with this diagram of a plant cell?
1. Plant cells do not contain mitochondria
2. The nucleus and the chloroplast have been labelled the wrong way round
3. The cell wall and the nucleus have been incorrectly labelled

(b) How many pairs of chromosomes are there in the cell?
(c) What is the diploid number of chromosomes in these cells?
13.
E
The following drawings-show the sequence of events early in cell division.
(a) Is the division meiotic or mitotic?
(b) How do you know?
14. Give two examples in each case of organs or tissues in which you would expect
(a) meiosis, (b) mitosis to be taking place.
15. An animal has 36 chromosomes in each of its body cells. How many of these chromosomes came from its male parent?
