|
|
Gram Positive
|
1) Thick peptidoglycan
2) Teichoic acid |
|
|
Gram Negative
|
1) Thin peptidoglycan

|
Endosymbiotic Theory
|
1) Small prokaryote engulfed by large prokaryote

|
Mitochondria- function and would a cell function without it? Can it divide?
|
1) ATP synthesis (energy factory of the cell)
2) Cell CANNOT divide without the mitochondria because ATP is needed for EVERYTHING 3) So, if you have a malfunctioning mitochondria, the cell is not going to survive |

|
Eukaryotic characteristics
|
1) nucleus
2) membrane organelles 3) histones 4) polysaccharide cell wall 5) mitosis |
|
|
Active Diffusion: group translocation
|
-occurs only in prokaryotes
-chemically alters molecules being transported |
|
|
Hypertonic
|
more solute outside of cell, so h2o moves to the outside of the cell. causes cell to SHRINK
|
|
|
Hypotonic
|
Water moves INTO cell, solute content is greater inside the cell. causes cell to BURST.
