The document summarizes the key parts and functions of animal and plant cells. For animal cells, the main parts are the cell membrane, cytoplasm, and nucleus. The cell membrane controls what enters and exits the cell. The cytoplasm is the jelly-like interior where cell activities occur. The nucleus acts as the control center storing DNA. For plant cells, the main parts are the cell wall, cell membrane, cytoplasm, chloroplasts, and nucleus. The cell wall provides structure, while chloroplasts facilitate photosynthesis to produce food. Both cell types share a nucleus that controls the cell and cytoplasm for internal processes.

4. You need to identify the different parts
of a typical animal cell and relate the
parts to the functions.
parts of animal cell:
• cell membrane, cytoplasm, nucleus

5. According to the cell theory, proposed over
150 years ago:
• Most cells are very tiny and can only be seen with
the aid of a microscope. A human body is
composed of billions of cells!
• The cells in the human body consist of blood
cells, skin cells, brain cells and many others and
each type of cells has different functions.
• Despite their differences, most cells in living
organisms have similar structures and functions.

6. Cell
Membrane
• A cell membrane keeps all the parts of the
cell inside.
• It controls what enters and exits the cell
such as water, nutrients and waste and
thereby protects and supports the cell.
• It is the outermost layer in the animal cell.

7. Cytoplasm
• Inside the cell, there is a large fluid-filled
space called the cytoplasm.
• It is a jelly-like substance composed of
mainly water as well as substances like
dissolved nutrients.
• The cytoplasm fills up the space between the
nucleus and the cell membrane.

8. Nucleus
• The nucleus is located in the cytoplasm of the
cell.
• It controls and regulates all cell activities. It is
the "control center" of the cell and it contains
the cell's DNA.
• It has a similar function to the brain of the
body which is helping to control eating,
movement, and reproduction.

15. You need to identify the different parts of a
typical plant cell and relate the parts to the
functions.

• cell wall, cell membrane, cytoplasm,

17. • A cell membrane
keeps all the parts of
the cell inside.
Cell
Membrane
• It controls what
enters and exits the
cell such as water,
nutrients and waste
and thereby protects
and supports the
cell.
• It is found just inside
the cell wall in the
plant cell.

18. • The cell wall is found in
plant cells but not in
animal cells.
• This is the outermost
layer in the plant cell. It is
stiff and rigid and helps a
plant keep its shape.
• Cell walls allow materials
like water and nutrients;
waste, oxygen and carbon
dioxide to pass to and
from the cell membrane.

19. • Chloroplasts are only
found in plant cells. They
are responsible for
photosynthesis.
• Every green plant you
see is working to convert
the energy from the sun
into sugars during the
process of
photosynthesis.
Chloroplast
• Plants are the basis of all
life on Earth. They make
sugars, and the byproduct of
photosynthesis is the
oxygen that we breathe.
• Chloroplasts are green
because of the pigment
chlorophyll.

20. • Inside the cell, there is
a large fluid-filled
space called the
cytoplasm.
Cytoplasm
• It is a jelly-like
substance composed
of mainly water as well
as substances like
dissolved nutrients.
• The cytoplasm is found
in both plant and
animal cells, filling the
space between the
nucleus and the cell
membrane.

21. • The nucleus is found in
both plant and animal
cells.
• It is located in the
cytoplasm of the cell.
• It controls and regulates
all cell activities. It is the
"control center" of the
cell and it contains the
cell's DNA.
• It has a similar function
to the brain of the body
which is helping to
control eating,
movement, and

30. Differences between Plant and
Animal Cells
Plant Cell
Animal Cell
•Plant cells contain
chloroplasts to make
food from solar energy
during photosynthesis.
•Underground parts of
plants usually do not
contain chloroplasts.
•Animal cells do not
contain chloroplasts.
•Plant cells contain cell
wall.
Animal cells do not have
cell wall.
