(vocabulary & identification)
What are the basic units that make up all living things?
Cells
Which type of cell has a cell wall?
Plant cell
Which tool is best for viewing tiny organisms in lake water?
Microscope
Which letter shows the cytoplasm?
c
Which structure controls the cell’s activities?
HINT* DNA CONTROLLER
Nucleus
Which cell part is known as the “command center” of the cell?
nucleus
Which two structures are found in both plant and animal cells?
Cell membrane and nucleus
Which tool is best for looking at blood cells?
Microscope
Which letter points to the nucleus?

B
Which structure allows materials to move in and out of the cell?
*HINT** BODY GUARD
Cell Membrane
Which two structures do plant cells have that animal cells do not?

Cell wall and chloroplasts
A cell has a rigid shape. What structure causes this?
Cell wall
Why wouldn’t a magnifying glass work to see tiny cells?

It does not provide enough magnification.
Which letter represents the cell wall?

e
Which student made a mistake if they labeled a plant cell with chloroplasts and cell wall, but said it was an animal cell?
The student is incorrect because animal cells do not have chloroplasts or cell walls.
Which structure is a jelly-like substance that holds organelles in place?
![]()
cytoplasm
A student observes a cell with chloroplasts, a nucleus, and a cell wall.
What type of cell is it? Provide one piece of evidence.
Plant cell; evidence includes chloroplasts or cell wall.
Which tool would be best to identify a whole plant and why?
Magnifying glass, because it shows the entire plant.

Match the letter to the structure that makes food for the cell.

A. Chloroplast
A cell diagram does NOT show a nucleus.
Why is this a problem?
* Why is the nucleus so important? What is its function?*
The nucleus controls the cell; without it, the cell cannot function properly.
Explain why chloroplasts are only found in plant cells.
Plants use chloroplasts to make food through photosynthesis; animals do not make their own food.
Explain how the shape of plant cells differs from animal cells and why.
** Remember what Ms. Bervine said about the difference between having a wall and not**

Plant cells are rigid due to the cell wall; animal cells are more flexible because they do not have a cell wall.
Explain when a microscope should be used instead of a magnifying glass.
A microscope is used when objects are too small to be seen with the naked eye, such as cells.
Which letter is pointing to a structure found only in plant cells?

A or E (chloroplast or cell wall)
Explain how the structures shown in the diagram prove whether the cell is plant or animal.
The cell is a plant cell because it contains chloroplasts and a cell wall, which are not found in animal cells.
