Parenchyma, collenchyma and sclerenchyma are strengthening tissues, so they're out of the picture. Xylem and phloem are conductive tissues, but phloem only conducts substances within the plant. ie, they are not in contact with the external environment, that means they can't bring water into the plant. Xylem on the other hand, are in contact with the external environment
xylem is a plant support tissue and it also helps in the transportation of water to different parts of the plant
Cambium is an active living layer btw the xylem and the phloem. It helps in grafting [exposing the cambium of two plants and tying them together].
I would like to ask... The questions er..... Are deyball pas jamb questions... Or its a collection of waec,neco,jamb and all sorts...? Plz hu is helping me
option d is d ans cos d xylem conducts majorly water cos its cell are dead&wit time deposition of liginin make it a dead cell &4ms d lumen dis now allows d conduction of water,cohesive forces&stronger dan adhesive force thus there's easy water cond.
Parenchyma,sclerenchyma&collenchyma're all living cells 4rom wen d're young til d get old but d xylem changes&4ms an empty column thus can conduct water,phloem cels translocate manufactured food i.e sucrose 2 oda parts of d plant wit d companion cell
Yeah bcuz Xylem conduct water upward from the root through the stem to the leaves
