Nucleus
 Big ball in the middle of the cell.
 Protects the Hereditary Information.
Nucleolus
 Little, dark spot inside nucleus.
 Makes RNA parts.
DNA
 Squiggly things inside the nucleus.
 The Hereditary Information for the cell.
Nuclear Envelope
 Membrane that protects the nucleus.
 Notice the nuclear pores.
Endoplasmic Reticulum
 Looks like a maze running throughout
the cell.
 Rough-has dots
 Smooth-no dots
 Moves proteins throughout the cell.
Golgi apparatus
 Looks like a ribbon scrunched in the
middle.
 Packages the Proteins.
Ribosomes
 Small dots can be attached or free.
 Makes proteins.
Mitochondria
 Oval with squiggly line inside
 Makes energy (ATP) by breaking down sugars
(carbohydrates)
Lysosome
 Little bubble (bigger than ribosomes,
usually near the golgi apparatus)
 Cleans up the cell.
Cell Membrane
 Covering of the cell.
 Protects the cell
Comparing Plant and Animal
Chloroplast
 Oval with stacks of pancakes
 Provides energy from sunlight and water.
Central Vacuoles
 Big bubble in the cell
 Holds water, ions, waste.
Cell Wall
 Extra covering around the plant.
 Provides structure and support.
