TYPE OF CELLS PROKARYOTES Cells that have a cell wall and cell
membrane but lack an organized nucleus. Example is bacteria
cell.
Slide 3
TYPE OF CELLS EUKARYOTES Cells that contain a defined nucleus
that contains the genetic material. Examples are animal cells and
plant cells.
Slide 4
organelles is a specialized subunit within a cell that has a
specific function, and is usually separately enclosed within its
own lipid bilayer.
Slide 5
CELL MEMBRANE For animal cells, the cell membrane forms the
outside boundary that separates the cell from its environment. Its
structure is essentially a double layer of fat with embedded
proteins. Its main function is to control what substances come into
and out of the cell.
Slide 6
NUCLEUS The nucleus is a large oval structure that acts as the
brain of the cell, controlling all of the cells activities. It is
made up of the nuclear membrane, chromatin and nucleolus.
Slide 7
CHROMOSOMES The nucleus contains thin strands of genetic
material called chromatin. When the cell begins to divide, the
chromatin strands coil and condense to form structures called
chromosomes.
Slide 8
NUCLEOLUS a non-membrane bound structure found inside the
nucleus. Function made ribosomes.
Slide 9
CYTOPLASM Is a thick, clear, gel- like fluid found between the
cell membrane and the nucleus. Most cell activities take place in
the cytoplasm Is where the Cell organelles are found floating in
the cytoplasm.
Slide 10
MITOCHONDRIA rod-shaped organelles called the power-houses
produce most of the energy the cell needs to carry out its
functions. Muscle cells and other very active cells have large
numbers (1000s) of mitochondria. Less active cells might have only
one mitochondria.
Slide 11
ENDOPLASMIC RETICULUM Is a maze of passageways Function carry
proteins and other materials from one part of the cell to
another.
Slide 12
Smooth ENDOPLASMIC RETICULUM Is smooth no presence of
ribosomes. is involved in lipid synthesis and steroid synthesis. It
is also involved in drug detoxification.
Slide 13
Rough ENDOPLASMIC RETICULUM surface of the membrane of RER is
studded with ribosomes (another type of organelle) function of RER
is the synthesis and manufacture of proteins in ribosomes
Slide 14
RIBOSOMES Ribosomes are small, grain-like bodies either
attached to the endoplasmic reticulum or free floating in the
cytoplasm. Ribosomes are factories that produce proteins. These
proteins are passed to the ER, then transported to the Golgi
Bodies.
Slide 15
RIBOSOMES
Slide 16
GOLGI BODIES structures that look like a flattened collection
of sacs and tubes that serve as the cells mail-room. Function:
receive proteins from the ER, package them, and deliver them either
to other parts of the cells, or release them to outside the
cell.
Slide 17
GOLGI BODIES
Slide 18
LYSOSOMES small, round, membrane enclosed. Functions: break
down food particles and old cell parts. Then the substances
released can be recycled and used to build new parts.
Slide 19
Slide 20
VACUOLES membrane-bound organelles Functions: store water,
food, and other materials needed by the cells but they can also
contain waste products. Vacuoles are more prominent in plant cells,
and typically occupy more than 30% (and up to 80%) of a plant cells
volume.

Slide 24
Slide 25
CELL WALL The cell wall is a rigid layer of non-living material
that surrounds the cells of plants. It is made of a tough, flexible
material called cellulose (Wood contains lots of cellulose.) The
cell wall functions to protect and support the cell.
Slide 26
CHLOROPLASTS Chloroplasts are large green organelles that
function to capture energy from sunlight and use it to produce food
for the cell. Remember: 6CO2 + 6H2O C 6 H 12 O 6 + 6O2
