Porous; protects cell, allows things in and out selectively.
|
|
|
Cytoplasm
|
soupy liquid; All other organelles float here
|
|
|
Nucleus
|
porous nuclear membrane; communicates with surrounding cytosol
|
|
|
DNA

In nucleus; contains genetic info., passed from parents to offspring, copied and put into new cells when they produce
|
|
|
Nucleolus
|
In nucleus; produces ribosomes
|
|
|
Chloroplasts
