Answer:
Usually the terrestrial
roots show a branched network that helps in anchorage andabsorption of water
and minerals from soil to the plant.
While in aquatic
plants, roots show modifications and deviation from their normal function.
e.g., in
plants like Trapa, Tinospora the roots are green and highly branched to
increase thephotosynthetic area, whereas in plants like Jussiaea. They get
inflated due to air project outof water so to help the plant in floating and
exchange of gases.
Difference between
roots of aquatic plants and terrestrial plants are as
Aquatic Plants
Terrestrial
Plants
Roots may be absent, e.g.,
Wolffia. If roots are present they are not well developed. Usually thin
adventitious roots are present.
Vascular strands are poorly
developed.
Modified to carry out
photosynthesis food storage and exchange of gases.
Roots are well developed with
root cap and root hairs and branches.
Vascular bundles are well
developed.
Provide anchorage and help in
absorption of nutrients from soil.
