The Cell Theory
1
Cells are the basic unit of structure - all critters are made up of cells
2
Cells are the basic unit of function - all cells carry out the Life Functions
3
All cells come from preexisting cells
Exceptions to the theory
Viruses
Mitochondria
Chloroplasts
Relate the functions of the cell organelles to the Life Functions.

Regulation
controls what enters & leaves the cell - SIZE
Excretion
All wastes ext through the membrane
Transport
All materials are ABSORBED by the membrane
Nutrition
Ingestion of food
Growth
The membrane must increase in size
Synthesis
Photosynthesis
Reproduction
They have their own DNA make more of themselves
Synthesis
Make proteins at their ribosomes
Synthesis
Lots of molecules are made here
Growth
An increase of material will cause growth
Transport
Diffusion
Respiration
Site of Aerobic Respiration
Synthesis
Make proteins at their ribosomes
Reproduction
They have their own DNA make more of themselves
Reproduction
Mitosis originates here
Synthesis
Making of NEW chromosomes
Regulation
DNA controls all cell activities
Synthesis
Makes proteins
Growth
The addition of proteins leads to growth
Excretion
Stores wastes
Nutrition
Stores food
