Parts and Functions of Plant
and Animal Cells
• Objective: To identify and describe the
parts and functions of a plant and
animal cell
• Essential Question: What are the major
functions of organelles in a plant and
animal cell?
Turn and Talk
1. Turn to the person sitting left of you.
2. Make a list of all of the cell parts that you
know from a plant and animal cell.
3. Be prepared to share with the class.
Stand and Share
• One person from each pair stand up.
• Listen to the parts of the plant and animal
cell that are shared.
• If you have the same items then sit down.
• If your items are DIFFERENT continue to
stand.
Who was the first person to
discover cells?
Robert
Hooke

Cells
• A cell is the smallest unit of life that
conducts all life functions.
Major Structures
• Cells have major structures known as
organelles.
Major Cellular Organelles
• Cell wall
• Cell membrane
• Nucleus
• Vacuole
• Chloroplast
• Mitochondria
• Cytoplasm
Plant Cell
Animal Cell
nucleus
cytoplasm
mitochondria
cell membrane
vacuole
What is the difference between the
two cells?
• Animal cells only
• Plants have:
have:
• chloroplasts
• cell membrane
• cell walls
• They don’t have
chloroplasts
because they
don’t make their
own food.
Both Cells Have:
•
•
•
•
•
cytoplasm
cell membrane
vacuoles
mitochondrias
nuclei

Functions of Cell Parts:
• cell wall- provides shape and support for
the plant cell; is mostly made of cellulose
Cell membrane
• cell membrane- controls the flow of
material into and out of the cell
• Diffusion is when materials move from an
area of higher concentration to an area of
lower concentration.
• Osmosis is the movement of water across
the cell membrane.
Cytoplasm:
• Cyto means “cell”
• Plasm means “liquid”
• Cytoplasm- a jelly-like substance found in
a cell
Nucleus
• nucleus- the control center of the cell; it
also contains genetic materials
Mitochondria
• mitochondria- converts sugar into energy
• It is known as the powerhouse of the cell
Vacuole
• vacuole-acts as a temporary storage
center
Chloroplasts
• Chloroplasts- contain chlorophyll used
to make food in plant cells
Ticket out the Door: True or False
1. Plant and animal cells have chloroplasts.
2. The mitochondria is known as a
temporary storage center.
3. Osmosis occurs in the cell membrane.
4. Animal cells have a large vacuole.
5. Cytoplasm is found in both the plant and
animal cell.
