A. True
Explanation
Cytoplasm IS the jelly-like stuff in a cell. The organelles kind of float around in it.
4.
A plant cell has 2 main things that an animal cell doesn't. Check the TWO things.
Correct Answer(s)
C. Cell wall
F. Chloroplasts
Explanation
Plant cells have the same parts as animal cells PLUS cell walls for structure and support, and chloroplasts to conduct photosynthesis.
5.
Functions of the Cell Membrane:
- Protects the cell by acting as a barrier.
- regulates the transport of substances in and out of the cell.
- receives chemical messengers from other cell.
- acts as a receptor.
- cell mobility, secretions, and absorptions of substances.
What are 2 functions of the Cell Membrane?
Correct Answer(s)
A. Protects the cell by acting as a barrier.
B. Regulates (controls) what substances can go in and out of the cell.
Explanation
Cell membranes touch blood. When blood passes by, food, water, and nutrients move through the cell membrane INTO the cell and waste moves out of the cell and back into the blood.
6.
The bone cells of these two creatures are basically the same.
Correct Answer
A. True
Explanation
Except for the reproductive cells made in the ovaries and testicles, cells in males and females are the same. A woman, for example could receive a blood transfusion from a man and vice versa. The heart is made up of cells and could be transplanted from a man to a woman.
7.
Although cells have the same basic parts, they can look very different and perform different functions. After watching
the BrainPop video on cells, what types of cells are these?
Correct Answer
A. The top is a red blood cell, the bottom is a nerve cell
Explanation
This is an important question. Cells have the same basic parts BUT can LOOK different and perform different functions. The cells on top are red blood cells which transfer food, water, and nutrients to cells and carry waste away. The cell on the bottom is a nerve cell that transmits senses.
8.
Unlike molecules, you can see most cells with a microscope.
Correct Answer
A. True
Explanation
Cells are MUCH larger than molecules. Cells are probably made of MILLIONS of molecules. You can NOT see molecules with a microscope, but you CAN see cells. I believe that I read somewhere that you can actually see the nerve cell of a giraffes neck WITHOUT a microscope.
9.
Which of the following parts of a plant cell performs a function similar to a skeleton in an animal?
Correct Answer
A. Cell wall
Explanation
A skeleton of an animal and the cell walls of plant cell (when joined together) help support the organism.
10.
What happens in the chloroplast of a plant cell?
Correct Answer
A. Photosynthesis
Explanation
Chloroplasts are filled with green chlorophyll. It is here that photosynthesis occurs.
11.
Every in an animal or plant cell has DNA. Where is the DNA of a cell located?
Correct Answer
C. In the nucleus
Explanation
DNA is located in the nucleus.
12.
What is the name of the green chemical in the chloroplasts of plant cells that allows
the chloroplast to conduct photosynthesis. ?
Correct Answer
B. Chlorophyll
Explanation
Chlorophyll is the green chemical in chloroplasts that is used in photosynthesis.
