Comparing Plant cells and Animal cells Lab Report
Introduction-
Mateo Pelaez
All living things are made up of tiny little units called cells. A cell is a basic unit of
all forms of life, but it is also the smallest living thing in the world. Cells consist of an
outside boundary called the cell membrane. Inside the cell there is a structure that
consists of material which is called the cytoplasm. My question is what are the
similarities and differences between a plant cell and an animal cell? I used the
microscope to examine the differences between a plant cell and an animal cell. I
hypothesised that a plant cell has a cell wall, cytoplasm and a nucleus. The difference
between both of these cells is that an animal cell has a cell membrane and a plant cell
has a cell wall. In order to test the hypothesis, I examined through the microscope the
differences between an plant cell and an animal cell.

Section IVPlant cellsElodea
400x
100x
Elodea description: In the elodea cell I observed the Cell wall, cytoplasm and the
nucleus. I also saw that the plant cell was mainly green. And the shape of the plant cell
was rectangular.
Onion cell-
400x
100x
Onion cell description:The color of the cell was basically white.The outside boundary of
the cell was a cell wall. I also saw cytoplasm and the nucleus. inside the cell.
Animal cells:
Cheek cell-
400x
100x
Cheek cell description: Under high power the cell looked like it had a nucleus,
cytoplasm and a cell membrane. The color of the cheek was yellowish mixed with a type
of brownish color.
Frog Blood Cell-
400x
100x
Blood cell description: The blood cells had cytoplasm,cell membrane, and a nucleus.
The color of the frog blood cell was a reddish pinkish color. The frog blood cell was
shaped like an animal cell that had a cell membrane. In the blood cell I was also able to
see how the cytoplasm was alive clearly inside the frog blood cell.
ConclusionMy hypothesis was what are the similarities and differences between a plant cell
and an animal cell. What I learned from my experience of looking into the microscope is
that the structure of a plant cell is quite similar and different from the structure of a
animal cell structure. Animal cells have a flexible structure called the cell membrane.
Plant cells have a outside boundary that maintains the plant from falling or breaking,
which is called the cell wall. Plant cells have chloroplasts which captures the energy
from sunlight and converts it into chemical energy. Chlorophyll is the structure that
gives a greenish color to a plant. When I saw the inside of the plant cell I saw that there
were chloroplasts inside the cell. Chloroplasts are organelles that capture the energy in
a process called photosynthesis. The purpose of the lab is to determine how to compare
plant cells and animal cells and their similarities and differences. What I thought that
was really difficult was finding the cheek cell. It was hard for me to find it because I
wasn't using the microscope correctly. Later I tried again to focus on the cheek cell and I
got a perfect view of the cell. We can get to know more about the cell and how to
determine the difference between the both different types of structures.
