Plant A+P Lab Test 1

Front 1

Is parenchyma a simple or complex tissue?

Back 1

simple

Front 2

what is aerenchyma?

Back 2

parenchyma cells with large intercellular spaces

Front 3

where is aerenchyma common?

Back 3

plants where a lot of gas exchange is necessary, frequently occurs in aquatic plants

Front 4

function of parenchyma cells?

Back 4

storage, support, photosynthesis

Front 5

what is chlorenchyma?

Back 5

parenchyma cells specialized for photosynthesis, contain chloroplasts

Front 6

do parenchyma cells have thick or thin primary cell wall?

Back 6

thin

Front 7

what are the most totipotent of all plant cells? capable of resuming meristematic activity?

Back 7

parenchyma cells (critical to wound healing, regeneration of tissues and cells, adventitious shoot and root formation, grafting of one plant part to another plant part), some parenchyma cells become lignified and lose the ability to dedifferentiate

Front 8

what are net-forming stellate parenchyma cells?

Back 8

form a thin sheet across air spaces

Front 9

purpose of armed parenchyma?

Back 9

provides maximal support while maximizes airspaces

Front 10

what are airspaces formed by?

Back 10

breakdown of cells

Front 11

why do aquatic plants have aerenchyma?

Back 11

buoyoncy, support, gas exchange

Front 12

function of thickened parenchyma cell walls in a seed?

Back 12

carbohydrate reserve

Front 13

what are druses crystals made of?

Back 13

calcium oxalate

Front 14

is collenchyma a simple or complex tissue?

Back 14

simple

Front 15

how can a collenchyma cell be identified?

Back 15

irregularly thickened primary cell wall

Front 16

what are the three type of collenchyma cell wall thickening?

Back 16

angular, lamellar, lacunar

Front 17

collenchyma is the primary supporting tissue for what?

Back 17

young, actively growing plant organs

Front 18

why are collenchyma cells white and glistening?

Back 18

large amounts of pectins that are very hydrated

Front 19

collenchyma are capable of dedifferentiating into...?

Back 19

meristematic thin-walled parenchyma cells

Front 20

older collenchyma cells may differentiate into....

Back 20

lignified sclerenchyma cells

Front 21

for angular collenchyma, where does the primary cell wall thickening occur?

Back 21

in the corners between cells

Front 22

for lamellar collenchyma, where does the cell wall thickening occur?

Back 22

on the tangential walls of the cells
