FC: The Importance of Cells

1: Scheleiden- All organisms consist of one or more cells. Schwann- The cell is the basic unit of structure for all organisms. Virchow- All cells arise from pre-existing cells. | Cell Theory: 3 Principles

2: Robert Hooke | In 1663, Robert Hooke discovered cells in a piece of cork, which he examined under his primitive microscope. Actually, Hooke only observed cell walls because cork cells were dead and without cytoplasmic content,

3: Matthias Schleiden | Matthias Jakob Schleiden, a german botanist, concluded that all plant tissues are composed of cells and that an embryonic plant arose from a single cell.

4: Theodor Schwann | Theodor Schwann, a German physiologist, who discovered the digestive enzymes pepins in 1836. He was a master microscopist who examined animal tissue , specifically working on tadpoles.

5: Rudolf Virchow | A German Pathologist and statesman, who explained the effects of disease in the organs and tissues of the body.

6: Prokaryotic Cells | Cells that lack a membrane-bound nucleus. These cells have few internal structures that are distinguishable under a microscope.

7: Eukaryotic Cells | All of the life kingdoms except Monera are Eukaryotic. They can be easily distinguished through a membrane- bound nucleus.

8: Nuclues | Nucleus- A membrane-enclosed organelle found in eukaryotic cells.

9: Ribosome | Ribosome- The protein builders or the protein synthesizers of the cell.

10: Central Vacuole | Central Vacuole- Soaks up all of the waste from the material in the cell.

11: Rough ER | Rough ER- The site of protein synthesis and uses ribosomes.

12: Lysosome | Lyosome- A cellular organelles that contain acid hydrolase enzymes to break down wate materials and cellular debris.

13: Smooth ER | Smooth ER- Found in a variety of cell types and it serves different functions in each and has no ribosomes.

14: Chloroplast | Chloroplast- Organelles found in plant cells and other eukaryotic organisms that conduct photosynthesis.

15: Cilia | Cilia- Slender protuberances that project from the much larger cell body.

16: Cell Wall | Cell Wall- The tough, usually flexiable but sometimes fairly rigid layer that surrounds some type of cells.

17: Flagella | Flagella- Hairlike structure that acts primarily as an organelle of locomotion in the cells of many living organisms.

18: Cell Membrane | -It controls what goes in and out of the cell. -It is used to engulf materials (food particles, invades, etc.) into the cell. -The cell membrane is selective permeable, regulating what leaves and enter so it can maintain homeostatis.

19: Homeostasis | -Homeostasis is the ability or tendency of an organism or cell to maintain internal equilibrium by adjusting its physiological processes. In other words, it means state of balance. -For example, when you run, your body temperature increases, so your skin blood vessels dilate and you sweat, which cools you. This keeps your body temperature in a narrow range.

20: Plant Cell | Chloroplasts: are cell organelles that capture light energy and produce food to store for a later time. Cell Walls: a fairly rigid structure located outside the plasma membrane that provides additional support and protection. Large Vacuole: are membrane-bound spaces used for temporary storage of materials. Photosynthesis: (function) captures sunlight energy and coverts it into chemical energy. Its structure also contains pigment known as chlorophyll. Plant cells do not contain lysosome, centrioles, and flagella (few).

21: Animal Cell | Centrioles: it is made of microtubules, is found only in an animal cell, and it is active during cell division. Animal Cell, a typical eukaryotic cell, are enclosed by a plasma membrane and contains a membrane-bound nucleus and organelles. It does not contain a cell wall, chloroplasts, and plasmodesmata.
