Chapter 3 Flashcards
the study of cells
cytology
major structural parts of the cell
cell membrane, cytoplasm, nucleus
cell membrane proteins
integral, peripheral
lie loosely on the inner and outer surface of the cell membrane
integral
inserted into and extend across the lipid bilayer
peripheral
coats white blood cells for traction
selectin
grabs WBC and tells it where to go
integrin
gel like material between the nucleus and cell membrane
cytoplasm
protein synthesis
rough er
lipid synthesis
smooth er
packaging and transport of proteins
Golgi apparatus
atp production
mitochondria
storage of various materials
vesicles
storage of water
vacuole
breakdown materials inside the cell
lysosomes
protein synthesis
ribosomes
cell division
centrosome
releases hydrogen peroxide and catalase to decompose it
peroxisomes
regulates movement of material between the nucleus and cytoplasm
nuclear envelope
loosely coiled strand of DNA and protein
chromatin
contains genetic material DNA which directs all cell activities
nucleus
movement of molecules or ions from an area of high concentration to low concentration
simple diffusion
movement of molecules from high to low using a protein carries to cross a membrane
facilitated diffusion
movement of water molecules from an area of high concentration to an area of low concentration of water
osmosis
