Study Set Content:
small, specialized units of the cell.
Organelles
made of protein tubulin and 25
nanometers in diameter.
Microtubules
composed of fibrous
proteins and are approximately 10 nm in diameter.
Intermediate filaments-
made of actin and are 8 nm in
diameter.
Microfilaments
Means small organ.
Organelles
2 TYPES OF ORGANELLES
Membranous and nonmembranous.
are rod shaped organelles with a
double membrane.
Its main function is to convert the stored chemical
energy in food molecules to stored chemical energy
in molecules of ATP.
Mitochondria
the smallest or the organelle about 25
nm in diameter and are nonmembranous. Their
function is to produce proteins.
Ribosomes
an organelle composed of
a network of enclosed channels.
Endoplasmic reticulum
2 TYPES OF ENDOPLASMIC RETICULUM
Rough and Soft ER
associated
with the nucleus and produces proteins for transport
and use outside the cell.
Rough endoplasmic reticulum RER-
is a distal
extension of the rough endoplasmic reticulum. It
produces lipid compounds and detoxifies material.
Smooth endoplasmic reticulum SER-
receives material from the ER and
other parts of the cytoplasm and serves as an
assembly and packaging organelle.
Golgi apparatus
flattened, membranous sacs, and it forms
vesicles to transport molecules it assembles.
Cisternae
its two major functions is to house the
genetic information of the cell and to direct many
cellular functions.
Nucleoli
are membrane bound sacs inside the cell.
Vesicles
2 SPECIALIZED VESICLES IN THE CYTOPLASM
-lysosomes and peroxisomes
-digests material with enzymes in a process known
as phagocytosis.
lysosomes
-uses enzymes to convert potentially toxic hydrogen
peroxide to water and oxygen.
peroxisomes.
Most cells have cilia but flagella is only found in the
sperm cells of humans
