cell wall
Definition
provides strengh and support to cell membrane
Term
nucleus
Definition
membraned covered organelle that holds the cells' DNA, the "brain"
Term
nucleolus
Definition
a dark spot inside the nucleus that makes ribosomes
Term
nuclear membrane
Definition
covers the nucleus and lets materials pass through
Term
ribosomes
Definition
smallest but most abundant organelles amino acids are hooked together to make proteins. They are found mostly on the E.R.
Term
endoplasmic reticulum
