BC: The End

FC: Cells Nikki Tanner Austin W.

1: Cell Theory | 1. All organisms are composed of one or more cells. 2. The cell is a basic unit of life. 3. New cells arise only from cells that already exist. | Nikki Tanner

2: Eukaryotes are organisms with a nucleus that contains DNA and other specialized compartments. This is able to carry out specific funtions, unlike a single celled prokaryote. Many single celled Eukaryotes have a flagella used for the movement of the cell. | Nikki Tanner

3: Prokaryotes are the smallest and simplest of cells. They are single celled organisms. One major difference, is they have no nucleus or other internal compartments or structures. They are not able to carry out specific functions. The most commonly found form of a Prokaryote is bacteria. Many Prokaryotes also possess a flagella. | Nikki Tanner

4: Plant Cells The 3 unique features of a plant cell, are the cell wall, chloroplasts, and a central vacuole. The cell wall surrounds the cell membrane, supporting and maintaining the shape while protecting and connecting the cell. Chloroplasts are organelles that use light to carry out photosynthesis. This organelle provides much of the energy to the cell. The central vacuole stores the water and other nutrients and substances. | Nikki Tanner

5: Animal Cells Animal cells are eukaryotic cells that contain nucleus, ribosomes, cell membrane, microtubules, rough and smooth ER, golgi apparatis, lysosome, and mitochondrion. Each organelle has a specific function in the cell. For example, the nucleus is the brain of the cell. It contains the DNA. | Nikki Tanner

6: Nucleus: The nucleus is basically the brain of the cell. It controls most of the functions and organelles. It plays a major role in controlling activity by regulating enzymes. Flagella: The flagella is a long tail-like structure that enables movement Mitochondria: This is a structure in most eukatyotic cells that creates the main resource for energy using organic compounds. Chloroplast: The chloroplasts are only found in plant cells, mainly on the leaves. They are used by capturing sunlight and using it to create energy by photosynthesis. | Nikki Tanner

7: Cell Membrane: The outer covering of both animal and plant cells. It keeps all the organelles and compartments of a cell intact and together. Central Vacuole: An organelle only found in plant cells. Its funtion is to store water and other various substances. This takes up most of the area of the cell, with enables the plant to stand upright. Cell Wall: Only found in plant cells, the cell wall is a rigid structure that protects the cell membrane and supports the cell. Ribosomes: A ribosome is an organelle found in most all plant and animal cells composed of RNA and proteins. It's main function is to create protein used by the cell. Lysosome: Is found in plant and animal cells. A small round organelle, used to digest waste and distribute nutrients. Rough ER: Where proteins are created. ( Protein synthesis) This provides structure. | Nikki Tanner

8: Homeostasis | Austin Wigley

9: Cell Membrane | Austin Wigley

10: Robert Hooke was one of the most important scientists of the 17th century. He contributed to the finding of cell theory. | Mattias Scheiden concluded that cells make up not only the stems and roots but every part of the plant. | Austin Wigley
