Question

write three differences between root and stem​

Answer 1

Answer:

Stems

This plant part lies above the soil surface emerging from the plumule of the embryo, exhibiting growth that is positively phototropic and negatively geotropic

These structures possess internodes and nodes from which different plant structures develop such as leaves, branches, flower buds, bracts

Functions –

Fluid and nutrition transport

Mechanical support

Appropriate arrangement of leaves and branches

Nutrients storage

Infinite growth

Production of new organs/tissues

Stem consists of the following morphologically – nodes, apical and axillary buds, internodes

They develop from apical meristematic tissue – vegetative cones

Roots

One of the major vegetative organs of vascular plants that are linked to their substrates are roots, ideally underground

Found below the soil surface, it emerges from the radical of the embryo

Exhibit growth that is positively geotropic and negatively phototropic

They are not differentiated into internodes and nodes

Functions –

Water absorption

Nutrient storage

Anchoring plants

Infinite growth

Vegetative propagation

Roots can be any of these depending on their origin and development – main root, adventitious roots, lateral roots
