Study Set Content:
Parenchyma tissues without chloroplast mostly function in what
Food and water storage
develop irregular extensions of inner wall that greatly increase the surface area. Found in nectar of flowers
Transfer cells
When a cutting is induced to grow what cell is responsible for dividing and growth
Parenchyma cell
flexible support for growing plants
Collenchyma cells
dead, thick walls that provide strength and support for the plant body
Sclerenchyma Tissue
means hard
Sclero
when are sclerenchyma cells dead
When they mature
Consists of cells with thick and tough secondary walls impregnated with (answer)
lignin
2 forms of sclerenchyma cells
Sclereids or stone cells and Fibers
They have lumen in the center of the cell
Fibers
Slightly gritty texture of pears, hardness of nut shells and pits of peaches and other stone fruits
Sclereids or stone cells
Composed of two or more kinds of cells
Complex Tissues
Two most important complex tissues in plants are:
Xylem and phloem
most complex tissues in woody plants are produced by
Vascular cambium
forms a protective layer covering all plant organs that consist primarily of parenchyma and parenchymalike cells.
Epidermis
forms a protective layer covering all plant organs that consist primarily of parenchyma and parenchymalike cells.
Periderm
A complex vascular tissue that conducts water and dissolved minerals throughout the plant body.
Xylem
What is the xylem composed of
parenchyma cells, fibers, vessels, tracheids, and ray cell
long tubes composed of individual cells called vessel elements that have thick secondary cell walls and are open at each end.
Vessels
may be found between the end walls of each pair of vessel elements and shows patterns mostly bar-like strips.
Perforation plate
