Nuclear Envelope
Physical Description: The membrane that is surrounding the
!
!
!
nucleus.
Job Description: Protects the nucleus, allowing only certain
materials to pass into or out of the cell.
Chromatin (DNA)
Physical Description: Thin Strands of genetic material.
Job Description: Contains instructions for directing all of the
cell’s functions.
Nucleolus
Physical Description: Small objects floating in the nucleus.
Job Description: This is where ribosomes are made
Mitochondria
Physical Description: Rod-shaped structures
Job Description: Known as the “powerhouse of the cell because
they convert food into energy that the cell uses
to carry out it’s activities.
Endoplasmic Reticulum
Physical Description: A maze of passageways.
Job Description: Passageways carry proteins from one part of the
cell to another.
Ribosomes
Physical Description: Small, grain-like bodies that are either
floating freely in the cytoplasm, or are
attached to the endoplasmic reticulum.
Job Description: Produce proteins for growth and repair of the
cell.
Golgi Body
Physical Description: Looks like flattened sacs and tubes.
Job Description: The cell’s mailroom. It packages proteins with
other materials and distibute them throughout the cell.
Chloroplasts

Vacuoles
Physical Description: Large water-filled sac(s) floating in the
cytoplasm
Job Description: Store food and other materials needed by the
cell
Lysosomes
Physical Description: Small, round structures floating in the
cytoplasm.
Job Description:Break down large food particles. also break
down old cell parts into substances that can
be used again.
Cytoplasm
Physical Description: A clear, thick, gel-like fluid found between
the nucleus an the cell membrane.
Job Description: Constantly moving, carrying organelles with it.

Physical Description
____ Cell Wall (p. 17)
A. In cells with cell walls (plants) it is located just inside the cell wall. In
cells without cell walls (animals) is a boundary that separates the cell
from it’s environment.
____ Cell Membrane (p. 17)
B. Large green structures floating in the cell’s cytoplasm. Found only in
the cells of plants (and some algae).
____ Nucleus (p. 18)
C. A rigid layer of nonliving material that surrounds the cells of
plants that is mostly made of a strong material called cellulose.
____ Chloroplasts (p. 22)
D. A large oval structure inside the cell.
Job Description
____ Cell Wall (p. 17)
____ Cell Membrane (p. 17)
A. Act as the “brain of the cell. controlling all the activities of the cell.
B. Helps to protect and support the cell. Materials, including
water and oxygen can pass through it easily
____ Nucleus (p. 18)
C. Controls what goes in and out of the cell: Food and oxygen enter,
Harmful waste products leave.
____ Chloroplasts (p. 22)
D. Capture energy from sunlight and use it to produce food for the cell.
