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

Lysosomes
They are only in plant cells, and Much like our
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.

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.
