Anatomy & Physiology I
Cytology List
Cell Structures.
Be able to identify the following structures on the models in lab and any diagram of the cell.
A. Cell (plasma) Membrane
microvilli – increases surface area of the cell membrane enhancing its ability to
transport material across by both active processes and passive processes of transport
cilia/flagellum – moves either materials along the surface of the cell or moves the
whole cell
B. Organelles in the cytoplasm
mitochondria - produce most of the ATP’s (energy molecules) for the cell
smooth endoplasmic reticulum – produces lipid and/or carbohydrates within
membrane bound vesicles, usually for secretion
rough endoplasmic reticulum – produces proteins within membrane bound
vesicles, for secretion or within lysosomes
centrosome with centrioles – used to move chromosomes during cell division
ribosomes - produces proteins
Golgi complex – packages material produced either by the smooth endoplasmic
Reticulum or rough endoplasmic reticulum into vesicles to secrete
or storage within the cell
lysosomes – contains digestive enzymes, used to breakdown “food” that the cell
pinocytosed or phagocytosed, or to breakdown old worn out cell
organelles
C. Nucleus – contains cell’s genetic material (DNA) – controls cell activities
nuclear envelope/membrane
nuclear pores – allow material to diffuse into and out of the nucleus
