Cell
• Is the basic unit of all
living things
Organelles
• Structures that carry out different jobs
within the cell.
Cell membrane
• The cell is surrounded by a membrane
• Allows certain molecules to pass in and
out of the cell
Cytoplasm
• The clear, jelly-like material between the
cell membrane and the nucleus
• The organelles float around in it
• Made mostly of water
Nucleus
• Structure that contains the cells DNA
• The control center of the cell
Nuclear membrane
• Dotted with thousands of pores,
• Materials move into and out of the nucleus
through the pores.
Nucleolus
• Synthesis Ribosomes
Chromatin
• Consists of DNA bound to protein
• Contain genetic information
Mitochondrion
• The energy for the cell is produced in the
mitochondria
• ATP is made here (ATP is the form of
energy used by the cell)
Ribosomes
• Produce the cell’s proteins (Protein
factories)
Endoplasmic Reticulum
• Rough ER- contains ribosomes along its
surface, transport proteins WITHIN the cell
• Smooth ER- lacks ribosomes, transport
lipids WITHIN the cell
Golgi Bodies/Apparatus
proteins and lipids are collected, wrapped in
a membrane, and released OUT of the
cell.
Vacuole
• Organelle used to store materials in the
cell
• Store excess materials such as water,
salts, proteins, and carbohydrates
Cytoskeleton/Microtubules
• A network of protein filaments that helps
the cell to maintain its shape
• Also used in movement
Lysosomes
• Sacs that contain strong digestive
enzymes used for breaking down large
molecules into smaller ones
• Used for digesting unwanted materials;
riding the cell of waste
Centrioles
• Only found in animal cells
• Aid in cell reproduction
