Cell Parts and Their Jobs
What are Cells?
Basic units of all living things
Building blocks of life
Needed for growing,
repairing/replacing damaged
cells
Cell Membrane
Location:
Surrounds all cells
Function:
–
–
Gives the cell shape
Controls what
moves into and out
of cell
Cytoplasm
Location: Throughout
the cell
Function:
Clear, jellylike material
–
Provides cushion for all
organelles
Nucleus
Location: Near center
of cell
Function:
–
Controls cell’s activities
–
Contains genetic
information in the form of
chromosomes/DNA
Nuclear Membrane/Envelope
Location: Surrounds
the nucleus
Function:
–
Protects nucleus from
the rest of the cell
–
Openings (pores) allow
materials to move into
and out of nucleus
Nucleolus
Location: Inside the
nucleus
Function:
–
Makes ribosomes
Chromatin
Location: Inside the
nucleus
Function:
–
Threadlike structures
that determine what
traits a living thing will
have
–
“genetic blueprints” for
cell operations
Chromosomes
Location: Inside the
nucleus
Function:
– Pairs of DNA
– Contain instructions
for cell activities
DNA : Deoxyribonucleic Acid
Location: Inside the
nucleus
Function:
–
–
Creates genes: determine
traits of organisms
Contains information for
making proteins
Endoplasmic Reticulum (ER)
Location: Cytoplasm
Function:
–
–
Network of tubes in the cell
Transports materials from
nucleus to cytoplasmthroughout cell
Smooth ER-no ribosomes
Rough ER-has ribosomes
Ribosomes
Location: Cytoplasm
or on the Rough ER
Function:
–
make proteins
Golgi Bodies
Location: Cytoplasm
Function:
–
Curved sacs that
package/store proteins
Mitochondria
Location: Cytoplasm
Function:
–
Sausage shaped
–
Breaks down nutrients to
produces energy
“Powerhouses” of the
cell
Vacuole
Location: Cytoplasm
Function:
–
Stores food, water, and
wastes
Larger in plant cells
Helps support the plant
Lysosomes
Location: Cytoplasm
Function:
–
Digests proteins, food,
water, and worn out cell
parts
Mainly found in Animal
Cells
Cell Wall
Location: surrounds
plant cells
–
–
Outside cell membrane
Rigid, non-living
Function: Protect and
support cell
Chloroplasts
Location: Cytoplasm
Contain green pigment
chlorophyll
Function:
–
Change light energy to
sugar [glucose] during
Photosynthesis
Plastid
Location: Cytoplasm
Function:
–
Contains pigments to
give plants color
