1. Plant and Animal Cells

2. Science Essential Question
How does a system of living and non-living things operate to meet the needs of the organisms in an ecosystem?
Science
Essential
Question

3. Something to Think About:
How are the life processes carried out by an individual cell like the life processes carried out by living things?

4. In this lesson, we will…
Distinguish between the basic structures and functions of plant and animal cells.
Identify the major parts of plant and animal cells, such as the nucleus, cell membrane, cell wall, and cytoplasm.
Compare and contrast basic structures and functions of plant and animal cells.

5. What are cells?
A cell is the basic unit that makes up all living things.
Cells are so small that you can see them only with a microscope.
Cells carry out life processes.

6. Some things that have parts such as:
A house
A school
Football stadium
A hospital
A car
A clock

7. What are the parts of a school?
Cafeteria
Library
Office
Classrooms
Bathrooms
All Purpose Room
Art Room
Music Room
Just as a school has parts, cells also have parts. Some parts are the same in both plant cells and animal cells.

8. Plant and Animal Cells
These parts are used to carry out different life processes. Remember the life processes – (MRS GREN).

12. What is inside an animal cell?
Cell Membrane
The cell membrane acts like a skin that holds the cell together.
It is the outer layer of an animal cell.
Cell membrane

13. What is inside an animal cell?
Cytoplasm
Cytoplasm is a jellylike material that fills the cell. The other parts of the cell float in the cytoplasm.
cytoplasm

14. What is inside an animal cell?
Nucleus:
The nucleus in the control center of the cell.
nucleus

15. What is inside an animal cell?
Mitochondria:
The mitochondria are the power sources of a cell
They break down food to release energy.
mitochondria

16. What is inside an animal cell?
Vacuole:
The vacuole is a storage container for food, nutrients, or wastes.
Animal cells have many small vacuoles.
Plant cells have a few large vacuoles.
vacuoles

20. What is inside the plant cell?
vacuole
nucleus
chloroplasts
cell membrane
cell wall
cytoplasm
Plant cells
have many of the same organelles as animal cells.
often have a box-like shape
are often a bit larger than animal cells
have additional organelles that animal cells do not have

21. What is inside the plant cell?
vacuole
nucleus
chloroplasts
cell membrane
cell wall
cytoplasm
Plant cell organelles
Nucleus
Cell membrane

mitochondria

22. What is inside the plant cell?
Cell wall
Additional outer covering, outside the cell membrane
Stiff structure
Provides strength and extra support
cell wall

23. What is inside the plant cell?
Vacuole
Unlike animal cells, plants usually have one LARGE central vacuole.
Stores excess water to keep the plant from drying out
Releases extra water when the plant needs it
Provides extra support
vacuole

24. What is inside the plant cell?
Chloroplast
Plants make their own food inside chloroplasts
Green structure
Energy from the sunlight is used to produce food for the plant inside the chloroplast
Plants are green because they contain a green chemical, chlorophyll
chloroplasts

25. What is inside the plant cell?
Chloroplast
Chlorophyll is able to use the energy in sunlight to make food
Plants that do not have chloroplasts (with the green chemical chlorophyll), are not green.
Chloroplasts are mainly found in the cells of leaves and stems of plants.
chloroplasts
