S: Seasons of Change

FC: Cells: Insides and out!!!! | By: Ashley Miller Ariana Fernandez and Gabrielle Casey

1: The three principles of the cell theory 1.All organisms are composed of one or more cells 2.The cell is a basic unit of life 3.New cells are made by other cells

2: Schwann: He observed that all plants were made of cells Schleiden: He observed that all animals were made of cells Virchow: He discovered that disease originates in cells Hooke: He dicovered plant cells and that cell walls are in cork tissue | The Scientists!!!!

3: Schwann | Schleiden | Virchow | Hooke

4: Prokaryotic | Prokaryotic cells have no nucleus. An example of that is bacteria... you know the stuff that makes you sick!! There is not a lot of space inside of a prokaryotic cell. It is rather smaller. Another thing to keep in mind is that prokaryotic DNA is circular and has no end.

5: Eukaryotic | A eukaryotic cell is much larger than a prokaryotic cell. It has a membrane-bound nucleus and its DNA is linear. A eukaryotic cell has much more space within it and has much larger ribosomes. A eukaryote is a plant or animal cell.

6: Animal Cells | Animal cells do not have cell walls! NO chloroplast either so don't you dare think that they do!! Instead they just have cell membranes. They have centrioles and very tiny vacuoles. Another thing is that plasmodesmata has no counterpart in helping the cell work.

7: Plant Cells | Plant Cells DO HAVE CHLOROPLAST!! They also have a cell wall. Vacuoles are generally large and present and they do not have centrioles. Another difference is that plant cells have plasmodesmata to help connect protoplasts of higher plant cells.

8: Ten Cell Structures | Nucleus: This controls the Eukaryotic cell's functions and the process of growth. It contains the DNA that makes you who you are!! Central Vacuole: Stores water and other nutrients, wastes, and iron. When full, it is rigid, helping plant to stand tall. Cilia: Single-celled organism with hair that helps moves substances across a cell's surface. Cell Wall: Is the structure of a plant cell that keeps everything inside. It is the layer of protection from damage. Lysosomes; Small, sphere organelles that digests and breaks down lipids, carbs, nucleic acids, and proteins.

9: Continued..... | Mitochondrion: Makes their own proteins and an organelle that harvests organic compounds too make ATP, the main energy that cells need. Golgi Apparatus: It is the packaging and distribution center of the cell. Cytoskeleton: The framework inside an animal cell and is held by the plasma membrane. Smooth ER: Outside of the internal membrane that moves proteins and other substances through the cell. Has a lipid layer with embedded proteins. Rough ER: Studded with ribosomes and transports protein made by ribosomes. Ribosomes: Protein synthesis; it is where proteins are made and is made up of RNA.

10: Cell Membrane | The cell membrane is the protective covering, especially for an animal cell, which acts as a barrier between the inner and outer environment of a cell. Its main function is to point out the boundaries of a cell. For animal cell, it acts as the "cell wall." In a plant cell it is the second layer of boundary.

11: Homeostasis is a state of equilibrium. Everything in which a cell is in equilibrium and functioning properly. The cell membrane protects the cell from outside stimuli that could disrupt a cell's homeostasis, and acts as a gatekeeper to what goes in and out of the cell. When there is too much of a molecule in the cell, the cell membrane makes it evacuate, maintaining homeostasis. | Homeostasis
