A cell organelle that helps make and package materials to be
transported out of the cell - ANS✔✔---Golgi Complex
Cell organelle filled with enzymes needed to break down certain
materials in the cell - ANS✔✔---Lysosomes
Produce hydrogen peroxide, detoxifies harmful substances, oxidizes
fatty acids, and protects cell from free radicals - ANS✔✔---
Peroxisomes
- Hollow, cylindrical organelle that disposes of unnecessary and
damaged proteins
- Contain enzymes that break down tagged, targeted proteins into
short peptides and amino acids - ANS✔✔---Proteasomes
- Located near the nucleus and help to organize cell division
- Form mitotic spindle during mitosis - ANS✔✔---Centrioles
Page 1 of 16
,A structure in cells containing two centrioles from which the spindle
fibers develop and organized - ANS✔✔---Centrosome
Point of growth for cilium or flagellum - ANS✔✔---Basal Body
Cell component responsible for energy production; powerhouse of the
cell - ANS✔✔---Mitochondria
Organelle responsible for protein synthesis - ANS✔✔---Ribosomes
Network of protein filaments that aid in intracellular support, cell
movement, and moves organelles. - ANS✔✔---Cytoskeleton
The basic unit of structure and function in all living things.
Composed of plasma (cell membrane), cytoplasm, cytosol, nucleus,
and cytoskeleton - ANS✔✔---Cells
Clear gel within the cell sometimes referred to as intracellular fluid
(ICF) -
ANS✔✔---Cytosol
All the fluid and components between the nucleus and the cell
membrane; includes the cytosol as well as the cytoskeleton -
ANS✔✔---Cytoplasm
Phospholipid bilayer that surrounds all cells and regulates what enters
and leaves the cell; also provides protection for cells. - ANS✔✔---
Cell membrane (plasma membrane)
Page 2 of 16
, Plasma membrane layers composed of phospholipid molecules
arranged with polar heads facing the outside and nonpolar tails facing
the inside.
Contains Transmembrane proteins, Peripheral proteins, Cholesterol,
and sugar (glycolipids and glycoproteins) - ANS✔✔---Phospholipid
Bilayer
Integral proteins in the cell membrane, that extends all the way
through the membrane touching both the ICF and ECF - ANS✔✔---
Transmembrane Proteins
The proteins of a membrane that are not embedded in the lipid
bilayer; they are appendages loosely bound to the surface of the
membrane. - ANS✔✔---Peripheral Protein
Cell division in which the nucleus divides into nuclei containing the
same number of chromosomes - ANS✔✔---Mitosis
The synthesis phase of the cell cycle; the portion of interphase during
which DNA is replicated. - ANS✔✔---S Phase
The second gap, or growth phase, of the cell cycle, consisting of the
portion of interphase after DNA synthesis occurs.
Growth and preparation for mitosis - ANS✔✔---G2 Phase
