Cell Mid-Unit Test Study Guide KEY
True or False: Identify each statement as either true or false.
1. True Cells are the structures that contain all of
the materials necessary for life
2. True Cells are found in all organisms
3. True Cells are sometimes specialized for
particular functions
4. False Living things cannot sense changes in
their environment
5. False Living things do not need to use energy
Vocabulary: Tell what each organelle’s function is below.
6. False All living things reproduce asexually
7. True Every living thing started as a single cell.
8. True All cells are surrounded by a cell
membrane
9. False All cells are able to survive on their own
10. True All cells come from other cells
11. True All cells contain cytoplasm and organelles
Chloroplast
Lysosomes
Vacuole
Contains chlorophyll, and is the site of
photosynthesis
organelle that breaks down waste for
the cell; “the clean-up crew” of the
cell
storage area for a cell (stores water
and other liquids)
Cell Membrane
Cell wall
Mitochondria
Layer that surrounds the cell and
protects it from its environment;
controls what comes in and out of the
cell
rigid layer of a plant cell to provide
protection and support
powerhouse of the cell; provides
energy
Golgi Bodies
Ribosomes
Endoplasmic Reticulum
packages and ships materials
throughout the cell
Organelle that functions as the
protein “factory”
"highway" in a cell to transport
materials
Nucleus
Nucleolus
Cytoplasm
The “control center” of the cell;
contains the cell’s DNA
Located in the center of the nucleus it
is the source of assembly and
ribosome production
fills up remaining space; jelly-like;
where some cell processes take place
Labeling: Identify each organelle below.
1. Cell wall
2. Cell membrane
3. Golgi bodies
4. Lysosomes
5. Rough ER
6. Nucleolus
7. Nucleus
8. Smooth ER
9. Cytoplasm
10. Mitochondria
11. Chloroplast
12. Vacuole
13. Ribosomes

The molecule that contains important information is called DNA
Unlike animal cells, plant cells have chloroplast to capture energy from the sun.
DNA, the genetic material of a eukaryotic cell, is located in the cells nucleus
The molecule that provides energy for cellular processes is ATP
The diffusion of water through the cell membrane is called osmosis
A tissue is a group of cells that work together to perform a specific job in the body.
What are the four molecules that make up the chemical composition of cells? Proteins,
charbohydrates, lipids, nucleic acids
8. What is the difference between Active Transport and Passive Transport?
Active Transport
Passive Transport
Uses energy
Low concentration to high concentration
does not need energy
high concentration to low concentration
9. The most abundant material found in cells is water
10. Anything that can live on its own is called an organism
11. What are the three parts of the cell theory?
1) The most basic component of any organism is the cell
2) All cells originate from other cells
3) All living things are made up of one or more cells
12. Cells are the “building blocks” of all living things.
13. Organs are made up of various tissues that work together to perform a specific job
14. List the similarities and differences between prokaryotic and eukaryotic cells.
Prokaryotic
Both
Eukaryotic
No nucleus
Has ribosomes
Nucleus
Circular DNA
Has DNA
Linear DNA
Simple cells
Complex cells
st
1 type of cells
Originated from prokaryotic
Stores DNA in the cytoplasm
More organelles
Stores DNA in the nucleus
15. When a cell membrane surrounds a particle, encloses it, and brings the particle into the cell, this is
called endocytosis
16. A change in an organism’s environment that affects the organism’s activities is a stimulus
17. Maintaining a body temperature of 37OC and a stable amount of sugar in your blood are both examples
of homeostasis
18. A person has about 200 different kinds of cells; each specialized to do a particular job. This means that
the person is multicellular
19. Two organelles that can generate ATP in a plant cell are mitochondria and chloroplast
