Introduction
Results
This experiment was done to understand how are
animal cells and plant cells are different. This
experiment was also to help me understand cells
better.
From doing the investigation we were able to
learn about cells and the difference of animal and
plant cells. We learned that all living organism on
earth is built upon cells and that there are parts
that build up a cell, like proteins and organelles.
There are also larger pieces called tissues and
systems. I learned that the main purpose of a cell
is to organize. Cells hold a variety of pieces and
each cell has a different set of functions. It is
easier for an organism to grow and survive when
cells are present. We also learned the difference
between animal and plants cells. As shown in the
table to the right. We also took pictures of the
cells close up.

Characteristics
Method
First, we took samples from different objects, like
plants and skin. Then we put each sample onto a
glass slide with a a dye to take a closer look. For
the human cells, we used a blue dye to be able to
look at the cells better. For the plant cells, we
used a yellow dye and the blue dye. After
recording what we saw, we took pictures of the
each cell at different amount of magnification.
After we did our experiment, i wanted to know
more about cells so i did some research to help.
Plant
Animal Cell
Cell Size
Large
Smaller than plant cells
Cell Shape
Rectangular
Circular
Vacuoles
A single centrally
located vacuole. It
takes up almost 90% of
the cell volume. The
vacuole stores water
and maintains turgidity
of the cell.
If any, there are a
number of small
vacuoles spread
throughout the
cytoplasm that store
water, ions and waste
materials.
Cell Wall
A rigid cell wall (made
of cellulose) is present
around a plant cell that
helps it maintain its
shape.
Cell wall is absent.
This allows animal
cells to adopt different
shapes.
Chloroplasts
Present. Chlorophyll is
the pigment that traps
sun's energy which is
utilized by plants to
make food through the
process of
photosynthesis. This
pigment is present in
the chloroplasts.
Absent. As animals
lack this pigment, they
cannot make their own
food.
Cell Division
Cell division takes
place by the formation
of cell plate in the
center of the dividing
cell. This becomes the
cell wall between the
two daughter cells.
Animal cells divide
with the formation of a
cleavage furrow. This
is formed as the
chromosomes move to
the ends of the
microtubule spindle
formed by the
centrioles.
Centrioles
Present only in lower
forms. Plants instead
have microtubule
organizing centers that
produce the
microtubules.
Present. Centrioles
help in division of
animal cells by
creating microtubule
spindles that pull the
chromosomes to
opposite ends for cell
division to occur.
Centrosome
Absent. Instead there Present
are two small clear
areas called polar caps.
Lysosomes
Absent
Golgi Bodies
In place of golgi
Complicated golgi
bodies, its sub units
bodies are located
known as dictyosomes close to the nucleus.
are present.

Present. Lysosomes are
vesicles that contain
enzymes that destroy
dead cell organelles
and other cells debis.
Conclusion
In conclusion, by doing our expirement, we
have found out the main idea behind the cell,
which is to organize, and the main differences
between plant and animal cells. We also were
able to get a closer look of the inside of a cell
through a microscope for a better
understanding. We were also able to learn
how to use a microscope and what dyes to use
when examining objects under a microscope.
