NucleusMuch like the brain, this is the control center and tells the cell what to do. How else would you know how breathe when you are not “thinking” about it?

Mitochondria and ChloroplastsThey allow the cell to breathe (respiration) and gives the cell energy, just like our lungs do for us.

LysosomesThey are only in plant cells, and Much like our intestines, lysosomes break down materials in the cell and get rid of waste.

VacuoleMuch like your stomach, the vacuole stores water and other materials for the cell until it is ready to be used.

Cell MembraneMuch like skin, the cell membrane is flexible protection allowing only certain things in and out.

1. Which picture represents 1. Which picture represents an animal cell?an animal cell?

A B

The answer is AThe answer is A

Think of the cell membrane of an animal call like a plastic bag. It holds everything inside of the cell, yet it is flexible with tiny holes which allow some things to pass in and out.

2. Which part of the human body 2. Which part of the human body is much like the mitochondria and is much like the mitochondria and chloroplast?chloroplast?

Mitochondria and Chloroplasts

Allows the cell to breathe (respiration)

and gives the cell energy, just like our

lungs do for us.

3. Why is the vacuole so much 3. Why is the vacuole so much larger in plant cells than in larger in plant cells than in animal cells?animal cells?

A. It is what makes plants green.

B. It holds lots of water for the plant and gives the plant structure.

C. Animal cells don’t need a vacuole.

D. Vacuoles get rid of waste and plant cells have more waste.

The answer is B The answer is B

Animal cells do have vacuoles, but the Vacuole in the plant cell is much larger. It holds water, food and sometimes waste to protect the rest of the cell. The large size of the vacuole also gives the plant its structure, which is why a plant will get droopy if it needs water.

4. These images come 4. These images come from the same type of from the same type of cell, but what kind of cell? cell, but what kind of cell?

The answer is plant cellsThe answer is plant cells

5. Which arrow is pointing 5. Which arrow is pointing to the ROUGH endoplasmic to the ROUGH endoplasmic reticulum on this animal reticulum on this animal cell?cell?Hint: This is one way the cell makes new materialsHint: This is one way the cell makes new materials

A

B

The answer is BThe answer is B

A

BB is pointing to the ROUGH endoplasmic reticulum. You can tell because it has little black dots representing the robosomes that are attached to it.

The ribosomes create proteins and the ER processes them.
