The document discusses the root systems of plants. It compares the fibrous root system of corn seedlings to the tap root system of mongo seedlings. The primary root of mongo seedlings can penetrate deeply into the soil, along with secondary and tertiary roots. The document also provides examples of modified roots in different plant species, such as the conical root of radishes used for food storage and aerial roots in ivy and orchids that help with climbing. Finally, it addresses that root hairs enhance a root's absorption capability by creating capillary spaces that increase the root surface area.

4. Description:
Corn Seedlings Mongo Seedlings
Corn root is a fibrous
root system. This
system do not
penetrate deeply into
the soil, and are made
up of large number of
roots that are similar in
SIZE.
Roots of a Mongo is
under TAP ROOT
system. This root can
penetrate deeply into
the soil which
compose of
PRIMARY ROOT
together with its
secondary and tertiary
roots.
