chapter 11 - plant cells

what is a glycoprotein?

a protein with a carbohydrate attached

what is a glycolipid?

a lipid with a carbohydrate attached

what are the two membrane proteins and their involvement?

integral which is involved in transport across the membrane and peripheral which is involved in cell to cell communication and cell identification 

what do integral and peripheral membrane proteins do?

they both can be attached to the cytoskeleton in or out of the cell to make cells highly dynamic and interconnected

what does the cell membrane produce?

an extracellular layer that provides shape, defense, and communication

what do plant and animals cells both produce?

filaments and ground substance

what do filaments do?

it resists tension

what does ground substance do?

it resists compression

what does no unity cells mean?

cell death

what is an example of fiber composites?

concrete being the ground substance to resist compression and steal rods being the fibers to resist tension

plant cells have a ___ and animal cells dont

cell wall, vacuole, and cholorplasts

how does this solute concentration affect the movement of water?

water will move from a low concentration to a high concentration across the membrane

what does osmosis result in?

in turgor pressure

what is turgor pressure?

when the membrane is pushed against the cell wall

how does turgor pressure help the plant?

it helps it stand upright and grow

what is in isotonic conditions?

flaccid

what is in hypotonic conditions?

turgid

what is the primary cell wall made of?

polysaccharide cellulose microfibrils and pectin

how does gelatinous solid support growth?

expansins

what are the two layers of plant cells?

primary and secondary

what does the secondary cell wall do?

it secretes between plasma membrane and primary cell wall
