Flashcards in Chapter 3 Summary Deck (18):
Basic unit of life, microscopic, >100 trillion make up human body, usually specialized to the function, determined by patters of gene expression in a process called cellular differentiation
inner cell mass
primary structure of a cell membrane. provides battier (homeostasis,) controls transport
double layer of phospholipid molecules (heads out, tails in) hydrophilic, hydrophobic
cholesterol, proteins, channel-transport, enzymatic-metabolism, receptor-communication, marker-identification, anchor-tissue integrity
gel like internal substance inside of cell
Nuclear envelope-double phospholipid bilayer,
nuclear pores-openings in the nuclear envelope,
chromatin- genetic material
A winding phospholipid bilayer of canals, tubes, sacs, and flat membranes
endoplasmic reticulum rough
-Can see ribosomes, looks textures
function in protein synthesis
endoplasmic reticulum smooth
no ribosomes, synthesizes certain lipids & ?
Nonmembraneous structures, made of 2 parts, each sub units is
Consists of stacked cisternae (Golgi bodies) cisternae produce vesicles (pinching off) (packaging facility)
Made of microscopic membrane sacs (pinched off from Golgi apparatus,) contain digestive enzymes, digest defective/old/useless cell parts
Composed of a double membrane system. Outer membrane, inner membrane w/cristae matrix. Cell respiration. Produce ATP. "Power plants" of cells.
Microvilli textures cells, extension of the membrane and cytoplasm of the cell. Back and forth, more than one.
Short cell process made of microtubules
One flegellum, spins/rotating motion
