Vesicles
Vacuole
A flexible covering that protects
the inside of a cell from the
environment outside the cell
Cell membrane
Structures within the cell which
have specialized functions; most
are surrounded by membranes

A stiff structure outside the cell
membrane
Cell wall
A long tail-like cell appendage
that helps the cell move
Flagella

that help the cell move or move
molecules away from a cell
Cilia
a network of threadlike proteins
that are joined together; form a
framework inside cell
Cytoskeleton
The part of a eukaryotic cell that
directs cell activities and
contains genetic information
Nucleus
The organelle found inside the
nucleus that makes ribosomes
Nucleolus
Small organelles that produce
proteins
Ribosome
A web-like organelle that stretches
from the nucleus into the
cytoplasm; ribosomes attach to it
and produce proteins
Endoplasmic reticulum
Specialized organelles that
process energy
Mitochondria
Organelles found only in plants;
they process light energy, water
and carbon dioxide to make glucose
Chloroplasts
Prepares and packages proteins
for their specific jobs
Golgi apparatus
Organelles that transport
substances from one area of the
cell to another
Vesicles
Organelles that store food,
water and waste material
Vacuole
Fluid inside cells that contains
salts and other substances
Cytoplasm
