FC: Lovely Cells By Nicole and Denasia

1: There are four scientists Mattias Schleiden, Theodor Schwann, Robert Hooke and Rudolph Virchow. They created a thing called cell theory. The cell theory states that all living things are composed of cells. They may be unicellular or multicellular. Cells are the basic unit of life. Cells arise from pre-existing cells. Credit for this theory is given to German scientists Theodor Schwann, Matthias Schleiden and Rudolph Virchow.

2: . | Hooke was an English scientist who looked at cork through a compound microscope and observed tiny room-like structures. These structures later became known as cells.

3: Schleiden was a German Botanist who viewed plant parts under a microscope and discovered that plant parts are made of cells.

4: Rudolph Virchow was a German physician that stated all living cells come only from other living cells.

5: Schwann was a German Biologist who viewed animal parts under a microscope and discovered that animals were made up of cells. He extended Schleiden's cell theory in plants to animals, stating that all living things are composed of cells.

6: Prokartyotes: A single-celled organism that does not contain a nucleus and other internal compartment, they are very small. Many prokaryotes include some bacteria that causes infection in humans they grow and divide very rapidly. Some don’t need oxygen to survive, and some can make their food. They don have membrane- bound organelles.

7: Eukartyotes: A single celled or multi-cellular organism who's cells contain a distinct membra ne-bond nucleus. Eukaryotic cells are multi-cellular.They have a nucleus, nuclear membrane and proteins.

8: Animal Cell: Animal cells are typical of the Eukaryotic cell, enclosed by a plasma membrane and containing a nucleus and organelles. Animal cells do not have a cell wall, they are single celled organisms that gave rise kingdom animalia. Animal cells help to develop a greater diversity of cell types.

9: Plant Cell: Plants are unique among the Eukaryotes, organisms whose cell have membrane enclosed nuclei and organelles, because they manufacture their own food, Chlorophyll, which gives plants their green color, enables them to use sunlight to convert water and carbon dioxide into sugars and carbohydrates and chemicals the cell uses for food.

10: Homeostasis: The ability of a cell to maintain equilibrium within its internal environment when dealing with external changes.

11: Lysosomes are organelles found in animal cells. They contain enzymes to break down waste materials.

12: Cell Membrane: Its a thin layer that goes around the surface of a cell. The cell membrane regulates what comes in and goes out of the cell.

13: Smooth Endoplasmic Reticulum: Looks like Rough E.R. without the Ribosomes. It helps transport the proteins.

14: Rough Endoplasmic Reticulum: Rough E.R is covered in Ribosomes. It’s main job is protein manufacturing.

15: Mitochondria are rod shaped structures that provide energy.

16: A nucleus is found in the middle of a cell and contains the cells genetic information.

17: Chloroplasts produce food for a plant through the process of photosynthesis. They are only found in plant cells.

18: Only found in Eukaryotic cells. The Golgi Apparatus processes and transports proteins.

19: The central vacuole is only found in plant cells. It stores water, food and waste.

20: Cilia: Slender organelles found in Eukaryotic cells that project from the cell. They allow the cell to move.

21: A Ribosome is often found in the Rough Endoplasmic Reticulum but can be found throughout the Cytoplasm. Its job is to make proteins.
