parts of the cell

name of cell parts and purpose
draw and lable cell.

1) nucleus- organelle that houses the DNA of eukaryotic cells
2) mitochondria- organelle that produces much of the ATP made by a eukaryotic cell
3)cell membrane- lipid bilayer with embedded protiens that enclose the cytoplasm; essential to the cell's cytoplasm; also called the plasma membrane
4) ribosomes- organelle on which protiens are made
5) golgi apperatis- organelle that packages and distributes molecuse produced by a erkaryotic cell
6) endoplasmic reticulum- cell membraines in the cytoplasm that transport substances made by the cell
