EUKARYOTIC CELLS
Contain membrane-bound organelles which include mitochondria, endoplasmic reticulum, and Golgi complex
EUKARYOTIC CELLS
Cell division involve mitosis.
EUKARYOTIC CELLS
DNA is not enclosed within the membrane.
PROKARYOTIC CELLS
Lack membrane-enclosed organelles
PROKARYOTIC CELLS
Usually divide by binary fission.
PROKARYOTIC CELLS
Structure: Phospholipid bilayer containing cholesterol and proteins and some carbohydrates; forms a selectively permeable boundary of the cell.
PLASMA MEMBRANE
Functions: Acts as a physical barrier to enclose cell contents; regulates material movement into and out of the cell; functions in cell communication Nucleus
