What is the primary purpose of taxonomy in biology?
Explaining physiology
Classifying organisms
Studying evolution
Analyzing genetics
What defines a prokaryotic organism?
No nucleus
Large size
Multicellular
Presence of mitochondria
What do chloroplasts do in plant cells?
Help with cell division
Maintain cell shape
Convert sunlight to energy
Store genetic material
What does the endosymbiotic theory suggest about cell evolution?
Cells change structure rapidly
Cells remain isolated
Only eukaryotes evolved
Cells merged with others
A node on a cladogram indicates what?
New species
Extinction event
Branch length
Common ancestor

Autotrophs obtain energy primarily from:
Other organisms
Mechanical digestion
Decay of organic matter
Sunlight or inorganic substances
Plants are classified as autotrophs because they can:
Absorb nutrients directly
Make their own food
Digest other organisms
Store food in roots

They are formed during photosynthesis.
They evolved from cyanobacteria.
They are exclusive to animal cells.
They only exist in multicellular organisms.
