A
- Cellular organization
- reproduction
- metabolism
- homeostasis
- heredity
- response to stimuli
- growth and development
- adaptation through evolution
2
Q
what are the Eukaryotic, Prokaryotic, Mitochondria and Chloroplast cell/organelle sizes
A
- eukaryotic = 10-100 micrometers
- prokaryotic = less than 5 micrometers
- mitochondria = 1-10 micrometers
- chloroplasts = 2-5 micrometers
3
Q
what is 1nm (nanometer) in micrometers
what is 1000nm in micrometers
A
1nm = 1000 micrometers 1000nm = 1 micrometer
4
Q
what are the requirements for natural selection
A
- variation
- inheritance
- selections
- time
5
Q
what is the Endosymbiosis theory
A
- that 2 key organelles in eukaryotes are derived from bacteria
6
Q
what were mitochondria and chloroplasts derived from
A
mitochondria = proteobacteria chloroplasts = cyanobacteria
7
Q
describe the features of a Prokaryotic cell
A
- are small
- have no mitochondria or chloroplasts
- no nucleus = DNA just sits in there
8
Q
describe the features of a eukaryotic cell
A
- big
- membrane-enclosed organelles
- have lots of organelles
- nucleus is bound in a membrane
