Tissue In Vascular Plants

vascular tissue

Covers and protects the surface of the plant.

dermal tissue

Makes up the bulk of the plant. Where most metabolic activities are carried out.

ground tissue

Transports water and nutrients throughout the plant.

Cell Type

Function

epidermal

Make up the majority of plant tissue; responsible for photosynthesis, storage, and also hormone production and release.

guard

Conducts sugar produced by photosynthesis to tissues throughout the plant.

cork

Conducts water and dissolved minerals and provides structural support.

xylem

Provides a thicker and more protective covering for the plant; forms the outer layer of bark on a tree.

parenchyma

Single layer of thin cells that produce a waxy cuticle to help reduce water loss.

collenchyma

Elongated, stringy cells with thickened cell walls that give the plant flexibility.

sclerenchyma

Cells with thick cell walls containing lignin that provide rigid support for the plant.

phloem

Capable of opening and closing to regulate gas exchange and water loss.
