Cell Organelles and Their Functions
2. Place the letter of organelle in front of the matching function. (16 marks)
1. _____ controls cell activities; contains the hereditary material
(DNA)
a. cell membrane
b. chloroplasts
2. _____ regulates what enters and leaves the cell; contains receptor
molecules
c. mitochondria
d. nuclear membrane
3. _____ site of photosynthesis; plants only
e. cytoplasm
4. _____ makes proteins; attached to the endoplasmic reticulum or
floating in cytoplasm
f.
5. _____ site of cellular respiration – chemical energy in sugars is
converted to energy the cell can use called ATP (adenosine
triphosphate)
h. ribosomes
6. _____ separate chromosome pairs during cell division; animals
only
g. rough endoplasmic reticulum
i.
lysosomes
j.
transport vesicle
k. vacuole
l.
7. _____ structures that give the cell its shape and help organize the
cell's parts; provide a basis for movement and cell division
nucleus
cytoskeleton
m. Golgi apparatus
n. centrioles
8. _____ a gel-like substance in which the organelles are suspended
o. cell wall
9. _____ interconnected tubules that carry material through the cell;
aids in making proteins
p. smooth endoplasmic reticulum
10. _____ membrane that encloses the nucleus; has pores to allow
transport of materials into and out of the nucleus
11. _____ contain enzymes used in cellular digestion of larger food
molecules and old cell parts; animals only
12. _____ rigid structure outside of cell membrane made of cellulose; plants only
13. _____ gathers materials from the endoplasmic reticulum and packages them into vesicles
14. _____ membrane-enclosed structure; transports material throughout or out of cell
15. _____ interconnected tubules that carry material through the cell; aids in making lipids and steroids
16. _____ membrane-enclosed structure: in plants large and stores mostly water
