What is a Cell?
 A cell is the basic structural and
functional unit of all organims
Nucleolus
 Function: Makes ribosome’s, which
move out of the nucleus and take
positions on the endoplasmic reticulum
 Facts:
Produce ribosome’s
Provides the cell with unique
characteristics
Nucleus
 Function: Communicates with the surrounding
cytosol via numerous nuclear pores
 Facts:
 Enclosed in a double membrane
 DNA is similar in cell DNA but depending on
what it is, they may be different. A Muscle cell
is going to be different than a fat cell.
Cytosol/Cytoplasm
 Function: Is the soup of the cell which all
other cell organelles reside and where
most cellular metabolism occurs
 Facts:
 Though mostly water it contains proteins
 Cytoplasm is a plural for cytosol
Centriole
 Function: Forms spindle fibers to
separate chromosomes during cell
divison.
 Facts:
 In groups of nine
 Perpendicular to each other
Golgi/Golgi Apparatus
 Function: Modify, sort, and package
proteins and other materials from the
endoplasmic reticulum
 Facts:
 Found near the nucleolus
 Numerous layers forming a sac
Lysosome




Function: Garbage disposal system
Facts:
Mostly in Animal cells
Necessary for intracellular
Peroxisome
 Function: Responsible for protecting the cell
from its own production of toxic hydrogen
peroxide.
 Facts:
 White blood cells produce hydrogen to kill
bacteria
 The oxidative enzymes in Peroxisomes break
down the hydrogen peroxide into water and
oxygen
Secretory vesicle
 Function: Hormones, neurotransmitters.
 Facts:
 packaged in secretory vesicles in the
Golgi
 transported to the cell surface for
release
Cell membrane




Function: Protects the cell
Facts:
Every cell has a cell membrane
Double layer of phospholipids (lipid
bilayer)
Mitochondrion/mitochondri
a
 Function: Provides energy that the cell
needs to move, divide, and produce.
 Facts:
 about the size of a bacteria
 have different shapes depending on the
cell type
Vacuole
 Function: Stores nutrients and waste
products helping increase cell size during
growth
 Facts:
 in animal cells they are generally small
 tend to be bigger in plant cells
Cell wall
 Function: Protective cell wall is made up
of polysaccharide.
 Facts:
 animal cells don’t have cell walls
 Provides and maintains the shape of the
cells and provides a protective barrier
Chloroplast
 Function: They are responsible for the
plants green color
 Facts:
 Have a double outer layer
 Thylakoids appear in stacks called grana
Smooth Endoplasmic
Reticulum
 Function: Breaks down lipid-soluble
toxins in liver cells and controls calcium
release in muscles
 Facts:
 Appears smooth by a electron
microscope
 Has varied functions suggest the
complexity of the eukaryotic cell
Rough Endoplasmic
Reticulum
 Function: Proteins synthesize of the
ribosome’s collect in the ER for transport
through out the cell.
 Facts:
 appears pebbled by a electron
microscope
 Large surface area on which chemical
reactions can occur.
Ribosomes
 Function: Packets of RNA and protein
that play a crucial role in both prokaryotic
and eukaryotic cells
 Facts:
 Site of protein synthesis
 Each ribosome has two parts; a large
subunit and a small subunit
Cytoskeleton/microtubules
/filament
 Function: provides and maintains cell
shape, but its primarily importance is in
the cell motility
 Facts:
 microtubules
 intermediate fibers
