16
Q

Endoplasmic Reticulum (both Rough and Smooth)

A

Rough - ribosomes, processes proteins
Smooth - no ribosomes, makes lipids

17
Q

Mitochondria

A

Carries out respiration and makes ATP

18
Q

Golgi Apparatus

A

Processes, packages, and secretes cell products

19
Q

Lysosome

A

Vesicle that digests macromolecules

20
Q

Endosymbiotic Theory

A

Proposed by Lynn Margulis
Explains origin of mitochondria, chloroplasts, internal members of Eukaryotic cells
Chloroplast used to be photosynthetic bacterium (Cyanobacteria)
