Generalized Animal Cell & Organelles
Golgi apparatus
• Modifies, distributes, and
packages secretory
products
• Distributes and
recycles cellular
membrane
Microtubules
Serve as “tracks” on which vesicles and
other organelles move around within the
cell • Shape and support the cell itself
Transfer vesicle
Rough endoplasmic
reticulum (RER)
• Segregation, modification,
and transport of proteins and
lysosomal enzymes
• Membrane studded with
ribosomes
Bound ribosome
• Attached to the RER
membrane
• Composed of two
subunits • Synthesize
proteins in the cytoplasm
destined for secretion
Free ribosomes
• Scattered throughout
cytosol • Composed
of two subunits
• Synthesize proteins
that function within
cytosol
Smooth endoplasmic reticulum (SER)
• Area of lipid synthesis and carbohydrate
metabolism • Role in detoxification of drugs
and other poisons • No ribosomes
Cytosol
• Gel-like intracellular fluid where many
of cell’s chemical reactions occur
Forming face of
Golgi apparatus
Maturing face of
Golgi apparatus
Lysosome
• Contains hydrolytic enzymes that the cell uses to digest
macromolecules, bacteria, viruses, and disabled organelles
Peroxisome
• Arises in the cytosol
from lipids and proteins
• Contains enzymes
that create hydrogen
peroxide that is used for
fat breakdown,
detoxification, and other
metabolic processes
Secretory granule
Nucleus
• Contains chromosomal DNA
packaged into chromatin fibers
• Plays central role in heredity
• Controls cellular activity
Nucleolus
• Site where
ribosomal RNA is
assembled, processed,
and packaged with
proteins into ribosomal
subunits
Nuclear envelope
Double phospholipid bilayer
membrane that segregates contents
of nucleus from cytoplasm
Nuclear pore
• Special permeable sites in
nuclear envelope that allow
specific macromolecules to pass
between nucleus and cytoplasm
• Each pore is bounded by eight
protein particles
Mitochondrion
• Power plant of the cell
• Provides energy in the
form of ATP through
oxidative phosphorylation
Basal body of cilium
• Identical in structure
to a centriole
Cilia
• Microtubular structure
which grows from the basal
body • Used for locomotion
• Enzymatic activity of dynein
(protein) releases the energy
from ATP required for motility
• Flagella have same
ultrastructure as cilia, but
they are longer, there is
usually only one per cell,
and they use more of an
undulating motion
Plasma
membrane
Cross section of cilium,
showing 9 + 2 arrangement
of microtubules with dynein
arms
Matrix space
Cristae
Outer & inner
membrane of
mitochondrion
Golgi saccule
Centrioles
Organelles containing nine triplet
bundles of microtubules
• Important role in cell division
Centrosome
Microtubule organizing center
Detail 1: Plasma membrane (lipid bilayer)
Controls exchange of materials between
inside and outside of cell Regulates
cell’s chemical composition
Integral membrane protein
Glycolipid
Hydrophilic
region
Hydrophilic

Hydrophobic
region
Transmembrane
channel protein
Detail 2: Cytoskeleton
• Provides structural organization to the cell
Supports organelles and allows their movement
Microfilament
Polysome
Microtubule
Mitochondrion
Plasma membrane
Peripheral protein
Cholesterol
Phospholipid
Surface membrane protein
Microtrabecular
