In one plant adventitious roots are modified for storage and in the other plant a lateral branch with short intemodes and each node bearing a rosette of leaves and a tuft of roots is found. They are
- Sweet potato and Pistia
- Eichhornia and jasmine
- Carrot and mint
- Turnip and Chrysanthemum
The Correct Option is A
Solution and Explanation
Sweet potato is the plant where the roots are modified in an organ that can store because of the adventitious root, by storing the carbohydrates and other food material.
Pistia have lateral branches that have short internodes and each of the nodes bears a rosette of leaves and a tuft of roots.

Morphology of Flowering Plants
Morphology in flowering plants tells us that every plant has two systems such as a root system and a shoot system. The root system digs deep into the ground and structures a system of its own. On the other hand, the shoot system is the one that is above ground level and includes various plant parts.
Root System
The descending part of the plant grows under the soil roots. During the germination process, the radicle from the seed grows earthward and branches out. The branches along with the primary root are called the root system. Roots lack chlorophyll and therefore they are not green in color. Roots are positively geotropic and hydrotropic, that is, they grow downwards ground and water, and negatively phototropic, which is growing away from light.
There are three types of root systems found in plants are as follows:
- TapRoot System
- Fibrous Root System
- Adventitious Root System
Shoot System
The stem is also an essential element of the plant. It is the ascending portion of the plant axis that bears branches, flowers, leaves, and fruits, as well as aiding in water and mineral conduction. It is the plant's aerial portion, brought about from an embryo's plumule or germinating seeds. Young stems are ordinarily green, but they finally turn woody and brown.
