On the first day back from our weekend, we discussed the shape and structure of animal and plant cells. Our table thought that the animal cell looked like the shape of a nerd, the candy. We thought because both of them looked bumpy and we described them both as "3-D blobs."
We thought the plant cell looks like the shape of a gear because of the rectangular spikes on 4 opposite ends of the plant cell, just like the cogs on a gear are on the four opposite sides of the gear.
Here is the link to the picture of an animal cell:

Hopefully, you can see the resemblences that our table found.
Then, later that day we made a chart of characteristics of both plant and animal cells. Some people gave some 2-D characteristics such as a deformed circle, which we then realized isn't a great characteristic because even thought they are small, both plant and animal cells are 3-D. So, a 2-D characteristic isn't that best way to describe these cells.
That day, we also made a chart of organelles, their functions and which kind of cell has them.
Here is a sample chart that I tried to make (sorry it will probably turn out horrible.)
Nucleus- Both animal and plant cell has it.
Controls everything that goes on in the cell.
Cell Wall- Only plant cell has it.
Gives protection and gives the cell structure.
Cell Membrane- Both animal and plant cell have it.
Helps contain the cell's organelles and controls what goes on in the cell.
Vacuole- Both animal and plant cell have it.
Stores nutrients and waste products and helps increase the cell size during growth.
Cytoplasm- Both the animal and the plant cell have it.
Holds the organelles in place.
Mitochondria- Only the animal cell has it.
Allows the cell to perform cellular respiration.
Smooth Endoplasmic Reticulum- Both the plant and animal cell have it.
Transports chemicals.
Rough Endoplasmic Reticulum- Both the plant and animal cell have it.
Structual Skeleton.
Chloropasts- Only the plant cell has it.
Contains the plant cell's chlorophyll.
Ribosome- Both the plant and animal cell have it.
Makes proteins out of amino acids.
The next day, which was Tuesday, we listed some animal cells and some plant cells.
Animal cells:
- Brain Cells
- Skin Cells
- Lung Cells
- Nail Cells
- Muscle Cells
- Tissue Cells
- Tongue Cells
- Blood Cells (Both Red and White)
- Berry Cells
- Leaf Cells
- Root Cells
- Stem Cells
- Flower Cells
- Seed Cells
- Salmonella
- Listeria
- Camphylobacter
- Staphlyococcus
- E. Coli
- Dipleococcus
*Bacteria cells are single-celled and animal and plant cells are multi-cellular (more than one cell.)
Then, our homework that night was to figure out if a paramecium (microscopic organism living in pond water) was an animal cell or not. The other question we had to figure out was how do they move. Here is what I found and shared to the class on Wednesday:
I could not figure out if a paramecium is an animal or a plant cell off the top of my head, so I had to look up this question on the internet. I found that a paramecium is not a plant nor an animal cell, but it is actually is a protozoa. A protozoa is an animal-like cell, but it's not actually an animal cell. It is found where there is moisture. (Like in pond water.)
Paramecium move using a cilia which surrounds the body of the paramecium cell. The cilia makes the paramecium move distinctly quickly.
After sharing our homework on Wednesday, we looked at pond water under a microscope to try to find paramecium and try to identify that they are paramecium by seeing if they have visible cilia. In our slide that Michelle and I made, we unfortunately could not find paramecium. All we saw was algae and air bubbles. Although we couldn't find anything though, Bria and Sarah could, so we took a look at their slide and drew and wrote observations. They looked like oval shaped bubbles with tiny lines around their structure, which we assumed was it's cilia.
That is what we did this week.
