- the cell is the basic organizational unit of life
- all cells come from preexisting cells
Nucleus

Nuclear membrane
protects contents of nucleus
Nucleolus
makes ribosomes
chromosomes
contains genetic information of cells
cell membrane
protective barrier around cell, controls what comes in and out (selectively permeable)
cell wall
provides shape and protection in PLANT CELL
cytoplasm
contains organelles, sugar, and water
mitochondria
supply’s energy
ribosomes
where proteins are made
lysosomes
digestion takes place
Endoplasmic reticulum
network of tubes that transports materials through cell
Rough ER
makes proteins
Smooth ER
makes lipids
Vacuole
stores nutrients, waste, and substances used by cell (water)
Golgi Apparatus
sorts and packages proteins
Cytoskeleton
chloroplasts
