Download TEST REVIEW- Cells ANSWERS 15

Cells Test Review Academic-due Tuesday 1/20
Test on Thursday, January 22
1. What is a cell? The smallest unit of structure in an organism
2. Name three objects that are made of cells. Answers may vary  humans, plants, bacteria
3. Name three objects that are not made of cells. Answers may vary  milk, plastic, cars
4. How do you know if something is made of cells or not made of cells? It is living or once was
living.
5.
Define the following words:
microscopic
So small it can only be seen with a microscope
organism
function
An individual form of life-you!
To do a specific job
unicellular
Made up of one cell
multicellular
Made up of many cells
organelle
Structures inside a cell
6. When an organism gets larger, describes what happens to its cells.
For an organism to grow, they have to produce more cells-more cells means bigger! Cells are
about the same size in animals.
7. Do all cells perform the same function? Explain.
No, for example in our body we have numerous different kinds of cells that are needed for us to
live, liver, brain, blood, lung, nerve……
Complete the following content frame:
Organelle
Cell
membrane
Function
Controls what comes into and out of the cell, think of a
strainer draining pasta noodles, only the water gets
through
Found in
animal cells
yes
Found in
plant cells
yes
Cytoplasm
The gel-like fluid where organelles are found
yes
yes
Cell wall
Ridged outer layer of the cell, think of how bark protects
a tree
no
yes
yes
yes
no
yes
yes
yes
yes
no
Nucleus
Contains the DNA, which controls the functions of the cell
Chloroplast
Captures energy from the sun and uses it to produce food
Vacuole
Stores water, food, waste, and other materials
Lysosomes
Uses chemicals to break down food and worn out cell
parts
Compare plant and animal cells by completing the
Venn diagram below.
Plant cell
Found in both
Chloroplasts
Nucleus
Cell wall
Cytoplasm
Vacuole
Cell
membrane
DNA
Animal cell
lysosomes
vacuoles
8. Identify the type of cell and label the parts.
cytoplasm
nucleus
Cell membrane
chloroplasts
Type of cell -plant.
Cell wall
Cytoplasm
9. Identify the type of cell and label.
Cell membrane
nucleus
lysosome
(breaks down food)
Type of cell-animal
vacuoles
(stores food, waste, etc)
10. True or false: Figure B is the building block of Figure A, if false explain why.
Figure A
Figure B
Lots of plant cells make up the sunflowers-cells are the building blocks of life!
Compare and contrast Prokaryotic cells and Eukaryotic Cells by
completing the Venn diagram below.
Prokaryotic cells
Eukaryotic cells
NO nucleus
Nucleus
DNA floats freely
Smaller than a eukaryotic
cell
Both are
living
organisms
DNA enclosed in nucleus
Larger than prokaryotic
cells
Unicellular
Most are multicellular
Not as complex
More complex
11. Draw and label a diagram of a prokaryotic cell.
12. Give an example of a prokaryotic organism. Bacteria
13. Draw and label an example of a eukaryotic cell.
14. Three examples of eukaryotic cells are: Animals, plants, and protists
15. Organisms that appear in a variety of forms that are neither plant nor animals are:
protists
16. Of all the protists that we have studied, which makes its own food? Algae makes its own food
17. What are three reasons protists are important: Bottom of the food chain, carry diseases,
produce some of the air
