The Eukaryotic cell – Parts and
their functions.
Use this PowerPoint to study the parts
and functions of the cell
Cell Wall (Plant Cell Only)
• Outermost part of plant cell. Rigid
structure. Protects the cell, helps it
maintain shape and gives structural
support.
Cell Wall (plant cell only)
Cell Membrane (Animal and Plant)
• Flexible covering that protects the
inside of a cell from the environment
outside the cell.
• Controls what enters and leaves the
cell.
Cell Membrane
Cell Membrane
Cytoplasm (Animal and Plant)
• Fluid/gel-like material inside a cell
that contains salts and other
molecules. Holds the cell’s
organelles.
Cytoplasm
Cytoskeleton (Animal and Plant)
• A network of threadlike proteins
throughout the cytoplasm.
• Gives the cell structure and helps it
move.
Cytoskeleton
Nucleus (Animal and Plant)
• Part of a eukaryotic cell that directs
cell activities and contains genetic
information stored in DNA.
Nucleus
Nucleolus (Animal and Plant)
• Produces ribosomes. Located inside
of the nucleus.
Nucleolus
Nuclear Membrane (Animal and Plant)
• Surrounds the nucleus. Contains
many pores (small openings).
Controls what enters and leaves the
nucleus.
Nuclear Membrane (envelope)
pores
Chromatin (Animal and Plant)
• Strands of genetic material in the
nucleus. Contains the instructions
that direct the cell’s activities.
Chromatin
Rough ER (Animal and Plant)
• Maze like organelle that spreads
throughout most of the cytoplasm.
• Forms passageways that move
material throughout the cell.
• Contains ribosomes on the surface.
Rough Endoplasmic Reticulum
Ribosomes (Animal and Plant)
• Site of protein production.
• Located on the surface of the rough
ER as well as in the cytoplasm.
Ribosomes
Ribosomes
Smooth ER (Animal and Plant)
• Maze like organelle that spreads
throughout most of the cytoplasm.
• Does not contain ribosomes on the
surface.
• Produces lipids and removes harmful
substances from the body

Smooth ER
Mitochondria (Animal and Plant)
• Produces useable energy for the cell.
“Powerhouse” of the cell.
• Energy produced by the
mitochondria is stored as ATP.
Mitochondria
Golgi Apparatus (Animal and Plant)
• Prepares proteins for specific jobs.
Packages the proteins into vesicles
that transport the proteins
throughout the cell.
• Also called the Golgi Body or Golgi
Complex
Centriole (Animal Cell Only)
• Important in cell division in animal
cells.
• Occur in pairs and are usually found
near the nucleus.
Centriole
Lysosome (Animal Cell Only)
• Contain substances that help break
down and recycle cellular
components.
Vacuole (Animal and Plant but different)
• Sac like structure that stores food,
water, and waste material.
• Plant cells have one large (central)
vacuole while the animal cells have
many small vacuoles.
Vacuole (smaller in an animal cell)
Vacuole (Larger
in a Plant Cell)
Chloroplast (Plant Cell Only)
• Membrane bound organelle that
uses light energy to make food
(glucose) through the process of
photosynthesis.
