Question

Stilt roots are found in
A. Ficus
B. Pandanus
C. Mirabilis
D. Portulaca

Answer 1

Hint: Plants are very important to life on earth. Basic parts of the plant are: Root, stem, leaves, fruits, flowers and seeds. Stilt roots are aerial adventitious roots which grow downwards from basal nodes of the main stem and fix strongly to the soil. Such supporting roots in plants are growing near banks of rivers, ponds etc.

Complete answer:
In order to solve this question, we need to know about the roots and its function.
The roots of a plant generally lie below the surface of the soil.
Roots can also aerial or aerating that is growing up above the ground or especially above water.
The first root that comes from a plant is called Radical.
The main function of roots is:
1. Absorption of water and nutrients and inorganic matter.
2. Anchoring the plant body and supporting them.
3. Storage of food and nutrients.
4. Vegetative reproduction.
After the dissection of roots, the arrangement of cells is root hair, epidermis, epilema, cortex, endodermis, and pericycle.
A true root system consists:
1. Primary roots
2. Secondary roots.
Stilt roots are Modified aerial adventitious roots which develop from the lower part of the stem node for mechanical support.
Stilt roots are generally present in plants growing in loose sandy soils.
For example: Pandanus.
Ficus: It’s a member of the Ficus genus of plants which includes rubber trees and fig fruit trees, but when it comes to houseplants, most people refer to a weeping as simply a ficus.
Mirabilis: Mirabilis jalapa or four o'clock flower is the most commonly grown ornamental species of Mirabilis plant and is available in a range of colours.
Portulaca: A low growing ground cover type plant is called the portulaca or sometimes known as the sun rose or moss rose.

So, the correct option is option B. Pandanus.

Note: Prop roots are one of the modified roots for support.
These roots develop from the branches of the tree, hang downwards, and penetrate into the ground thereby supporting the tree.
Example: Roots of the banyan tree and Rubber plant.
A tuberous root or storage root, is a modified lateral root, enlarged to function as a storage organ.
