Cell Membrane• Thin membrane that surrounds the cell.• In plant cells, it is found just inside the cell
wall.• It is the outer covering of animal cells.• Provides support and protection for the cell.• Allows materials to pass in and out of the
cell.• Found in both animal and plant cells.• Often called a plasma membrane

Nucleus• A large, oval structure.• Known as the control center of the cell.• Acts as the “brain” of the cell by
regulating or controlling all of the activities of the cell.
• Found in animal and plant cells.

Nucleolus• A “little nucleus” inside the nucleus.• Produces ribosomes which are involved
in protein production.• Found in plant and animal cells.

Chromosomes• Thick, rodlike structures found in the
nucleus that are made of nucleic acids or DNA and RNA.
• Direct all cell activities, including growth and reproduction.
• Pass on the traits of the cell.• Found in both animal and plant cells.

Cytoplasm• Clear, thick, jellylike substance found
between the cell membrane and the nucleus.• Protects and supports the organelles and
moves materials around inside of the cell.• Is constantly flowing within the cell.• Found in both types of cells.

Ribosomes• Round, grainlike bodies.• Mostly found attached to the endoplasmic
reticulum, but can be found floating freely in the cytoplasm.
• Made primarily of RNA.• Are the protein-making sites of the cell.• Found in both plant and
animal cells.

Mitochondria• Rod-shaped structures.• Called the “powerhouses” of the cell.• They supply energy for the cell by breaking
down sugar into water and carbon dioxide.• Some very active cells that require a lot of
energy, like liver cells, may have more than 1000 mitochondria.
• Found in animal and plant cells.
