No end wall between cells
Xylem
cells have end walls with perforation
Phloem
Water and food
Phloem
Water and minerals
Xylem
No end walls between cells
Xylem
It is the dermal tissue system layer of cell in herbaceous plants. A complex tissue composed primarily of relatively unspecialized living cells.
Epidermis
The outermost layer of cells of young plant organs.
Epidermis
What do you call arial roots in which several epidermal cells may be thick like a sponge
Velamen roots
Fatty substance secreted by most epidermal cells wuthin and on the surface of the outer walls
Cutin
protective layer that cutin forms
Cuticle
Where does the thickness of the cuticle depends
how much water is loss through the cell walls by evaporation
The susceptibility of plants to herbicides may depend on
the thickness of wax layers
tubular extensions produced by epidermal cells of roots. It greatly increases the absorptive area of the surface
Root hairs
Specializes epidermal cells. Only differ in shape and that chloroplasts are present within them.
Guard cells
Small pores in leaves
Stomata
Special outgrowth or hairs
Trichomes
Guard cells that are modified that secrete protective or substances, modified as hairs that either reduce water loss as repels insects and animals that might otherwise consume them.
Glands
The outermost layer of the cells has covering a woody stem or root - that is, the outer bark that replaces epidermis when it is destroyed during secondary growth.
Periderm
Replace the epidermis once it is sloughed off after the cork cambium begins producing new tissues that increase the girth of the stem or root and is found in woody plants.
Periderm
Constitutes the outer bark and is primarily composed of somewhat rectangular and boxlike cork cells which are dead at maturity.
