Ch. 35 (FINAL EXAM)

Ch. 35-45 (not everything is tested. tested concepts are in the back of the wyrick handout)

function of plant roots (35)

1) absorption of water/nutrients

2) store carbs as starch

3) anchorage

function of plant stem (35)

1) connection

2) hold plants up

function of plant leaf (35)

1) photosynthesis

2) transpiration (H2O loss)

function of vascular tissue in plants (35)

transport of water/nutrients in root, leaf, & stems

function of dermal tissue in plants (35)

1) Root→H2O/nutrient absorption

2) leaf→central gas exchange
3) protection for ALL organs

function of ground tissue in plants (35)

1) root→storage of starch
2) leaf→photosynthesis

3) structure & support for all organs

function of parenchyma cells (35)

thinnest cell wall & largest central vacuole

1) root→storage

2) leaf→ photosynthesis
3) metabolism & structure

function of collenchyma cells(35)

unevely thick

1) support young shoots/seedlings

function of sclerenchyma cells(35)

lignified secondary cell wall (extra thick)

-mainly for protection

primary growth(35)

(apical meristem) MAIN PRIORITY

lengthening of shoot & roots (sunlight and water)

secondary growth(35)

(lateral meristem)

stem increases in girth(thickness) =support and stabilization
