anat 3

composed of cells and cell products

surrounds cell unit membrane at cells surface

• intra-face cytoplasm
• extr- faces outward

unique fuzzy coat external to the plasma membrane

extensions of membrane specialized in absorption

hairlike processes

hereditary disease in which cells make chloride pumps, but fail to install them in the plasma membrane

tail of the sperm

• plasma membrane
• passive transport
• active transport
• carrier=mediated mechanisms

process in which particles are driven through a selectively permeable membrane by hydrostatic pressure

the net movement of particles from area of high concentration to area of low concentration

flow of water from one side of a delectively permeable membrane to the other

channel proteins in plasma membrane specialized for passage of water

amount of hydrstatic pressure required to stop osmosis

ability of a solution to affect fluid volume and pressure in a cell

cells absorb water, swell and may burst

cells lose water shrivel

normal saline

• uni-carries one solute
• sym-carries 2 or more solutes in same direction
• anti-carries 2 or more solutes in opposite directions

carrier-mediated transport of solute throughgh a membrane down its concentration gradient

process that bring material into the cell

discharging material from the cell

cell eating

cell drinking

sytem of interconnected channels called cisternae enclosed by unit membrane

composed of parallel flattened sacs covered with ribosomes

small granules of protein and RNA

a small system of cisternae that synthesize carbohydrates and put the finishing touches on protien and glycoprotein synthesis

package of enzymes bound by a single unit membrane

digest and dispose of worn out mitochondria and other organelles

cell suicide

organelles specialized for synthesizing ATP
