CELLSCELLSThe Building Blocks of Life

Students will:1. Use pictures of animal and plant cells to identify the organelles.2. Compare/Contrast the organelles and structures of plant and animal

cells.3. Understand how living organisms depend on cells to carry out the life

functions of:Extracting energyGetting rid of wasteMaking new materials

4. Understand that organisms could not live without cells

intestines, lysosomes break down materials in the cell and

get rid of waste.

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.

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.

Vacuole does not get rid of waste,

the lysosome does

Back to

Question

YES!YES!

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.

A is pointing to the SMOOTH endoplasmic reticulum. It is considered smooth because it does not have ribosomes attached to it.

YES!YES!

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.
