Plant cells Flashcards
why is the cell wall rigid
water pressure
what is a straight chain of glucose
cellulose
cellulose is made up of bundles of
microfibrals
cellulose ____ branched, hemicellulose ___ branched
not, is
what is the function of hemicellulose
helps attach microfibrals to each other and forms the matrix that surrounds microfibrals
what makes hemicellulose
golgi aparatus
what is a glycoprotein
protein plus at least one carbohydrate
where is glycoprotein located
matrix
what is pectin
group of carbohydrates
pectin is a ____ that embeds ____ and hemicellulose
matrix, cellulose
what is the function of microfibrals
provide rigidity for pressure
when the cell wall grows it becomes
acidified
what hormone stimulates a decrease in pH
oxin
what happens when the pH drops
microfibrals become looser and the additional pressure causes them to stretch
microfibrals are not
elastic
