EUKARYOTIC ANIMAL CELLS Flashcards
are typically about ten times larger than prokaryotic cells. In animal cells, the plasma membrane, rather
than a cell wall, forms the cell’s outer boundary.
EUKARYOTIC ANIMAL CELLS
a nucleus and numerous other membrane-enclosed organelles. Like separate rooms of a house, these organelles enable specialized functions to be carried out efficiently.
Eukaryotic cell cytoplasm
The ______ membrane that surrounds eukaryotic cells is a dynamic structure composed of two layers of
phospholipid molecules interspersed with cholesterol and proteins.
Plasma Membrane
is the largest organelle in an animal cell. It contains numerous strands of DNA, the length of each strand being
many times the diameter of the cell.
Nucleus of a Cell
is an elongated membranous sac attached to the nuclear membrane.
Endoplasmic Reticulum
TWO FORMS: rough and smooth.
bound to the endoplasmic reticulum help assemble proteins that
typically are exported from the cell.
Ribosomes
lacks ribosomes and has an even surface, needed for the construction of molecules such as
carbohydrates and lipids, prominent in liver cells, where it also serves to
detoxify substances such as alcohol, drugs, and other poisons.
Smooth Endoplasmic Reticulum (SER)
an organelle that resembles a stack of deflated balloons. It is packed with enzymes that
complete the processing of proteins.
Golgi apparatus
are small, often spherical organelles that function as the cell’s recycling center and garbage disposal.
Lysosomes
are the powerhouses of the cell. Within these long, slender organelles, which can appear oval or
bean shaped under the electron microscope, enzymes convert the sugar glucose and other nutrients into
adenosine triphosphate (ATP).
Mitochondria
a dynamic network of protein tubes, filaments, and fibers, crisscrosses the cytoplasm, anchoring
the organelles in place and providing shape and structure to the cell.
Cytoskeleton,
