Get materials from enviroment to modify and use for energy, growth, repair, and maintenence. The two types are Autotrophic(plants) and Heterotrophic(animals)
Produce complex substances from simple substances (ex: photosynthesis = carbon dioxide and water ----> glucose and oxygen)
Ability to move from place to place
Not necessary to be considered living but increases probability of survival
Organism makes new individual(s)
Asexual- Single Parent, Offspring are clones of Parent
Sexual- Two Parents, offspring are unique
Not Necessary to be considered living but increases probability for the survival and continuation of a group or species.
1. All living things are made of cells
2. Cells are the basic units of all stucture and function of living things
3. All cells come from preexisting cells
Exception to the Cell Theory
-Have Genetic Material
-Not made up of cells
-Reproduce inside another cell (host cell)
Semi permeable membrane surrounding all cells that controls what goes into and out of the cell (Phospholipid bilayer)
The transport system throughout the cell
Rough- has ribosomes
Smooth- No ribosomes
Cells have watery internal and external enviroments
Keeps hydroPHOBIC tail away from water
Water will diffuse into the cell and the cell will expand
ex: Distilled water because there are no minerals and it is pure water
Lower solute concentration than cell
Water diffuses out of the cell, so the cell will shrink/shrivel.
Ex: Salt water
Higher solute concentration than cell
