BC: The End Thanks for learning about cells with us.
FC: Let's Learn our A C E's!of Cells! By Andrew Rodriguez and Christian Myers
1: A is for Animal Cell. | Inside of an animal cell, many organelles are collected and are surrounded in cytoplasm. | Fun Fact: Hey class, did you know that there are animal cells in your body?
2: C is for Cell Wall. | The Cell Wall is made up of proteins and carbohydrates. they support and maintain the cell's shape.
3: C is also for Cytoskeleton. | The Cytoskeleton helps maintain the cells shape. Its primary importance is in cell motility. Without the cytoskeleton, the internal movement of cell organelles, and muscle fiber contraction couldn't happen.
4: C is also for Centriole. | Centrioles, found in animal cells, form the spindle which helps move chromosomes apart during mitosis.
5: E is for Eukaryote. | A Eukaryote is a membrane-bound organelle. they contain a nucleus and a nucleolus. It is more complex then a prokaryotic cell. | A eukaryote's counterpart is a prokaryotic. a prokaryotic cell is one of the smallest and simplest cells. They lack a nucleus. these cells cause food to spoil and infection.
6: G is for Golgi Apparatus. | The Golgi Apparatus serves as the "packaging and distribution center" of the cell. It stores and packages materials to be exported from the cell.
7: We must interrupt our awesome, all-around amazing alphabet adventure to explain how we learned about cells and other interesting facts. | Please excuse letters I and K...
8: We know so much about cells because of the Cell Theory which is made up of three principles. - All living organisms are made up of cells and are either unicellular or multicellular - The cell is the basic unit of life - Cells are created from pre-existing cells This theory was developed by three scientists, Theodor Schwann, Matthias Schleiden, and Rudolph Virchow. In 1838 Schleiden concluded that all plants were made up of cells. In 1839 Schwann discovered that all animals were made up of cells. In 1855 Virchow proved that all cells come only from pre-existing cells.
9: The Scientists | Schleiden | Schwann | Virchow
10: Although the credit for the cell theory went mainly to the three scientists described earlier, their discoveries wouldn't have been made without Robert Hooke's discovery of the cell with his microscope. | Hooke's Microscope
11: Homeostasis is the ability of the body or cells to maintain and regulate internal conditions when dealing with external changes. This is important because if without internal balance, an organism can become ill or die. For example when we are cold, we shiver and shake because that is our bodies way of trying to keep us warm. | No Yes
12: Example of Homeostasis
13: Cell Membrane | The Cell Membrane is an outer layer that surrounds the cell. It also separates the cell interior, and is made of lipids.
14: Plant Cell vs. Animal Cell | The plant cell has almost the exact same structures as the animal cell, but it also has organelles that the animal cell does not have. A plant cell has chloroplast, a cell wall, and a giant vacuole. | Plant Cell
15: Thank you class for paying careful attention to that. We may now continue our A C E's!
16: M is for Mitochondria. | The Mitochondria provide the energy a cell needs to move and divide. They are the power centers of the cell. They convert energy into forms that are usable by the cell.
17: M is also for Microtubules. | Microtubules are fibrous hollow rods that function primarily to support and shape the cell. They are a main part of the cytoskeleton.
18: N is for Nucleolus. | The Nucleolus is the center region of the nucleus. It is the producer of ribosomes in the cell.
19: N is also for Nucleus. | The Nucleus is like the control center of the cell. It has a double membrane around it that separates it from the cytoplasm. It contains the DNA responsible for providing the cell with its unique characteristics.
20: R is for Rough Endoplasmic Reticulum. | The RER is responsible for moving proteins throughout the cell and is important in the synthesis of other proteins. The reason it is called rough endoplasmic reticulum is because it is attached with ribosomes.
21: S is for Smooth Endoplasmic Reticulum. | The SER looks like a set of smooth tubes. Its job is to move protein and other substances through the cell. Its other function is to make lipids and break down toxic substances.
