Root

Why the epidermis of root lack waxy cuticles?

• prevent dehydration

• allow water absorption

• protect root cap

_____cell is inactive and replaces damaged meristem cells.

• peripheral cells

• Storage parenchyma cells

• Quiescent

• apical meristem cells

Endodermis has a selective filter called _____.

• hypodermis

• epidermis

• Casparian Strip

Xylem and phloem belong to the __ tissue system.

• dermal

• vascular

• ground

• cortical

In plants, ground tissue that is between the vascular tissue and dermal tissue in a root or eudicot stem is

• epidermis

• cambium

• fibers

• cortex

I extend horizontally from the primary root and serve to anchor the plant securely into the soil. This branching of roots also contributes to water uptake, and facilitates the extraction of nutrients required for the growth and development of the plant.What am I ?

• adventitious root

• tap root

• lateral root

• root hair

Root hairs :

• are epidermal cells

• are multicellular filaments

• arise from the endodermis

• function in support

• two of the above

The apical meristem in the root:

• is located behind the root cap

• produces cells which become incorporated into the root cap

• gives rise to the primary meristematic tissues

• is a region of active cell division

• all of the above

9. In the zone of elongation, the root cells begin to elongate primarily by filling their cell vacuoles with ____.

• salt

• water

• minerals

10. Which of the following is not a function of roots?

• Store food

• Transport water and dissolved minerals

• Acts as a support for the leaves and flowers

• Anchor plants in soil

• All of the answers are functions of root
