13. the greek word karuon means "nut." the prefix pro-

means "before," and the prefix eu- means "true." thus,

prokaryote means "before nut," and eukaryote means

"true nut." how do these meanings relate to structural

differences between these two cell types?

The main difference between prokaryotes and eukaryotes is the nucleus.

Prokaryotes have it's DNA dispersed on the cytoplasm.

Eukaryotes have a differentiated nucleus where all the DNA locates and do all process.

So, the before and after "nut" could talk to you about the differentiation of this nucleus, rounded structure inside the cell with its wall.

meiosis is the first to occur after the nuclei of opposite of opposite mating types fuse

voluntary muscles are controlled by the cerebellum.
