What are chloroplasts?
where photosynthesis occurs. they contain chlorophyll, a green substance that absorbs light needed for photosynthesis
what does a bacterial cell look like?
a prokaryote, consisting of a cell membrane, outer cell wall, a circular strand of dna inside, ribosomes and plasmids (small rings of dna)
