hydrophobic lipid tails
centrosome
Mitochondria & Chloroplast
Mitochondria
sites of cellular respiration
ATP
sugar
plants, animals, fungi
mitochondrial matrix
enzymes
helps with cellular respiration
Chloroplast
photosynthesis
solar energy to chemical energy
chlorophyll
thylakoids
stacked
granum
stroma
outside liquid
chloroplast DNA
ribosome
plastids
amyloplast
Endosymbiont theory
Mitochondria and plastids were once bacteria that got swallowed by a larger cell, and they started living and working together as one organism.
