Cells: Form and Function
Directions: Use pp 74-78 in the GREEN sciencesaurus book and Lesson 7 reading (pgs. 83-85) to
answer the following.
Sciencesaurus1. DIFFERENT organisms MAY use different structures to do the same
job.
2. Cells make up living things and carry out the activities that keep living
things alive.
3. A cell itself is a living unit.
4. New cells can come only from existing cells.
5. Many organisms are unicellular or made of only one cell.
This one cell carries out all the activities that keep the organism alive
and allow it to reproduce
6. Earthworms, trees, mushrooms, and humans are multicellular
or made of many cells.
7. Many cells in multicellular organisms are specialized to do only
certain jobs. Examples are root cells, leaf cells and nerve cells.
8. Each specialized cell in a multicellular organism works with
other similar cells to carry out a specific job.
9. Having specialized cells for different jobs allows a multicellular
organism to perform more functions than unicellular organisms.
10. Large organisms have cells that are about the same size as those
in small organisms, but large organisms have more cells than small organisms.
NOTE: AS YOU GROW, YOU GET MORE CELLS,

THE CELLS DON’T GROW.
11. Cells come in all sizes and shapes but most are microscopic or so
tiny you need a microscope to see them.
Define: Match the definitions on the right with the words on the left.
1. Cell D
A. Cells that do not have membrane-bound structures.
2. Prokaryotic A
B. Usually located near the center of an animal cell which is home to the
3. Eukaryotic C
chromosomes. The “brain” of the cell.
4. Unicellular F
C. Cells that have membrane-bound structures.
5. Multi-cellular H
D. A basic unit of structure and function of life
6. Cell membrane E
E. Encloses the cell and allows some materials to pass through it, but not
7. Cytoplasm K
others.
8. Organelles L
F. Made of only one cell.
9. Nucleus B
G. Genetic structures that contain the information used to direct cell
10. Chromosomes G
activity.
11. Mitochondria I
H. Made of many cells.
12. Chloroplasts J
I. Use oxygen to transform the energy in food to a form the cell can use
13. Cell Wall M
to carry out its activities.
J. Food-making structures in plant cells that contain chlorophyll.
K. Gel-like fluid, which is mostly water, that takes up most of the space
inside a cell.
L. Carry out the activities that keep the cell alive.
M. The outer barrier that provides extra support for the cell and gives it a
shape. Made mostly of a rigid material called cellulose.
