Cell Organelles

cell wall
The cell wall is a rigid layer that lays outside of the cell membrane. It protects the cell from injury. ex: security guard
cell membrane
The cell membrane controls what molecules pass in and out of the cell. ex: a doorman
nucleus
The nucleus is very important it holds DNA, it also directs most of the activity in the cell. ex: the mayor
cytoplasm
The cytoplasm is the liquid that fills, the liquid is a jelly type liquid the cell so that all of the parts to the cell do not just float around. It also maintains the internal pressure of the cell. ex: like a deflated balloon.
ribosome
The ribosome is also important because it creates the proteins that the cells need, they can be found in the ER or floating around in the cytoplasm. ex: small factories
mitochondria
The "mighty mitochondria" produces the energy for the cell called ATP which fules most action in the cell. ex: power plant
chloroplast
The chloroplast converts the suns rays into energy the cell can use. ex: solar power plant
endoplasmic reticulum
The endoplasmic reticulum makes the proteins. ex: factory complex
cell theory
There are three parts to the cell theory.
-all living things are made up of one or more cells
-all cells are created from pre-existing cells
-cells carry out the functions needed to support life
the body organization
cell>tissue>organ>organ system>organism
prokaryotic and eukaryotic
eukaryotic has a nucleus
prokaryotic does not
