a)

True

b)

False

6.

The following is a statement from the Cell Theory. True or False: Cells are a complex structure in living things.

a)

True

b)

False

7.

Cell Wall...

a)

Supports and protects the cell of a plant.

b)

Supports and protects the cell of an animal.

c)

Supports the nucleus inside the cell.

8.

Cell Membrane...

a)

Controls what comes in an out of the cell. Can be found in both cells.

b)

Wraps around the cell wall of a plant.

c)

Controls the amount of food a cell has.

9.

Endoplasmic Reticulum (ER)...

a)

passageways that carry proteins from one part of the cell to another. Like a highway system.

b)

Where you go if you're in a medical emergency situation.

c)

This acts like the brain of the cell.

10.

Vacuoles...

a)

Create protein for the cell.

b)

Are blobs of water and food for the cell.

c)

Require the cell to drain every few days.

11.

Mitochondria...

a)

THE POWERHOUSE OF THE CELL. Makes the most energy for the cell.

b)

This gives a plant the color of green.

c)

Helps with transporting proteins.

12.

Chloroplasts...

a)

Huge role in photosynthesis for plants and give plants a green color.

b)

Act like the brain of the cell.

c)

Allows oxygen and water to move in and out of the cell.

13.

Cytoplasm...

a)

Gives plants their green color.

b)

Is a gel like substance that other organelles float in.

c)

Has an electric charge that powers the cell.

14.

Nucleus...

a)

Creates proteins for the cell.

b)

Acts like the brain of the cell.

c)

Acts like the mailroom of the cell and delivers proteins throughout the cell.

15.

Ribosomes

a)

Helps with making DNA in the cell.

b)

Creates proteins and then sends them through the ER so they can be transported to different areas of the cell.

c)

A gel like substance that other organelles float in.

16.

Golgi Apparatus...

a)

Think of it as the mailroom of the cell, it packages up proteins and delivers them to areas of the cell.

b)

Gives the plant structure because of how rigid and tough it is.

c)

Allows oxygen and water to go in and out of the cell.

17.

Centrioles...

a)

Helps with cell division by separating the chromosomes.

b)

Creates proteins in the animal cell.

c)

Acts like the brain of the cell.

18.

Lysosomes...

a)

They take care of the worn out organelles, food particles and consume viruses and bacteria in the cell. The clean up crew.

b)

They package up proteins and deliver them throughout the cell.

c)

They provide structure for the plant cell because of how rigid it is.
