All life is made up of tiny units called cells.
The two most broadest classification of cells are
- Prokaryote- without a nucleus(ex. bacteria)
- Eukaryote- with a nucleus
Cells contain various machinery inside of them called organelles which perform functions for the cell. These organelles are
- 1) nucleus- which contains the genetic material of the cell[also the site of RNA and DNA activities like replication
- 2) endoplasmic reticulum- which contains the rough ER(contains ribosomes) and the smooth ER(synthesizes lipids)
- 3) vacuole- contains nutrients of the cell
- 5) lysosomes- digestive enzymes
- 6) vesicles- small body's in the cell
- 7) Golgi Apparatus- Packager of the cell
- 8) centrosomes- contain centrioles which aid in mitosis[cell division]
- 9) cytoskeleteon- organelle that maintains cell shape
- 10) ribosomes-The ribosomes are a large complex of RNA and protein molecules, This is where proteins are produced
