Basic units of life
First described in 1665
Study of cells related to the development of the
microscope
Humans are composed of trillions of cells



All living organisms are made of one or more
cells
The cell is the basic organizational unit of life
All cells come from pre-existing cells
Organelle
Description/Function
Cell membrane
Separates inside of the cell from external
environment; controls flow of materials
into and out of cell
Cell wall (plant
cell only)
Tough, rigid structure lying just outside a
plant cell’s membrane; provides support
for the cell
Cytoskeleton
Filaments and tubules that provide a
framework for the cell, helping it maintain
its structure and providing “tracks” along
which vesicles and organelles can move
Cytoplasm
Includes the cytosol, the organelles and
other life-supporting materials such as
sugar and water; contained by the cell
membrane
Organelle
Description/Function
Nucleus
Controls all cell activities,
responsible for mitosis
Nucleolus
Makes ribosomes which help
make proteins
Nuclear membrane Protects contents of nucleus
Nuclear pores
Allow materials, such as
ribosomes, in and out of
nucleus
Organelle
Mitochondria
Ribosomes
Endoplasmic reticulum
Vesicles
Description/Function
Where energy is released from glucose to
fuel cell activities (powerhouse of the
cell)
Help to produce proteins, which make up
a cell’s structure and are required for
activities necessary for the cell’s survival;
some ribosomes float in cytoplasm and
others are attached to the endoplasmic
reticulum (rough ER)
Network of membrane-covered channels
that transport materials made in the cell;
is connected to the nucleus (rough vs.
smooth)
Membrane-covered sacs that transport
and/or store material inside the cell and
sometimes help these materials cross the
cell membrane to enter/exit the cell
Organelle
Description/Function
Golgi body
Sorts and packages proteins and other
materials for transport out of the cell
Vacuoles
Contain water and other materials and are
used to store and transport small molecules;
plant cells have one large vacuole while
animal cells tend to have many smaller
vacuoles
Chloroplasts
(plant only)
Found only in plant cells; trap energy from
the Sun to make glucose, which is broken
down in the mitochondria to provide energy
for cell activities (animals must get glucose
from the food they eat (autotropic vs.
heterotropic)
