Term
ANTON VAN LEEUWENHOEK
Definition
- First to see bacteria and blood cells
Term
THEODORE SCHWANN
Definition
- He came out with the first two parts of the cell theory
1) All organism composed of one or more cells
2) The cell is the basic unit of life
Term
ROBERT HOOKE
Definition
- Invented the microscope
- Look at a piece of cork and saw things that look like little boxes and named them cells, meaning little cells.
Term
RUDOLF VIRCHOW
Definition
- Developed the 3rd. part of the cell theory
3)All cells come from existing cells
Term
ORGANELLES
Definition
1) Lysosome
2) Mitochondria
3) Nucleus
4) Ribosome
5) Vacuole
6) Chloroplast
7) Cell membrane
8) Cytoplasm
9) Cell wall
Term
LYSOSOME
Definition
Cleans out the cell of old organelles and bacteria. Digests food particles with enzymes, pinched of pieces of golgi apparatus
Term
MITOCHONDRIA
Definition
Produce energy when food is broken down, often called the "powerhouse of the cell". Converts sugar into ATP (Adenosine Triphosphate)
Term
NUCLEUS
Definition
Controls the cell telling it what to do
Term
RIBOSOME
Definition
Makes protein for the cell. Where proteins are made, and often connected to the endoplasmic reticulum. A cell may have as many as 500,000.
Term
VACUOLE
Definition
Holds water for the cell. Liquid-filled, may store food, water, minerals, or wastes. In plants it takes up a lot of space. There maybe more than one.
Term
CHLOROPLAST
Definition
Uses the sun to make glucose. Found only in plant cells. Found in the cytoplasm of green plant cells, contain chlorophyll, traps the energy from light, and is where photosynthesis takes place.
Term
CELL MEMBRANE
Definition
Lets material in/out the cell. Gives the cell shape, holds the cytoplasm, and controls what moves into and out of the cell.
Term
CYTOPLASM
Definition
Keeps the cell inflated and keeps organelles from bumping into each other. Jellylike material (cytosol and organelles), most of the cell's chemical reactions take place there, and made up of mostly water and some chemicals.
Term
CELL WALL
Definition
Add structure to a cell and protects the cell (cell wall of a fungus is made of chitin and from a plant is made of cellulose). Found only in plant cells. Forms a thick outer covering outside the cell membrane, gives the plant support and shape.
