Plant Biology: Regions and Modifications of Roots

The region just above the root cap where rapidly dividing cells cause root length growth.

A thimble-like structure at the root apex that protects the tender root tip as it grows through the soil.

The region where cells of the root increase in length, following cell division.

The region where cells differentiate and mature to perform specific functions, located above the elongation zone.

Fine, thread-like structures that grow from epidermal cells of the root to absorb water and minerals from the soil.

Roots that have changed structure and function, not limited to water absorption, in various plants; for support, storage, or respiration.

Modified roots which grow from the stem of a plant to provide extra support.

Roots that arise from parts of the plant other than the main root, often stems and sometimes leaves.

Vertical roots that grow upward from the roots of plants in swampy areas to obtain oxygen.

Protects the growing tip of the root as it pushes through the soil.

Rapid cell division region at the root tip enabling root growth.

Root cells enlarge and lengthen in this region, after dividing.

Cells mature and specialize to perform root functions.

Fine structures on roots that absorb water and minerals from soil.

Roots that have adapted to perform functions beyond water and nutrient absorption.

Supporting roots growing from the stem, like in Banyan trees.

Roots growing from stems or leaves, rather than the main root.

Vertical roots in swampy plants, which helps respiration.
