Approach Solution -2
Halophytes include pneumatophores.
Halophytes are plants that can only survive in salty environments. These plants grow close to the coast.
The halophytes Phinophera, Salva terra at Vicinia, etc. are examples.
Despite the fact that these plants thrive in well-watered places, the high concentration of salts in the water prevents them from flourishing. As a result, from secondary roots that are horizontal, the lateral roots develop upward into the air. Halophytes are what you see.
These roots, known as pneumatophores, have the capacity to exchange gases. They have breathing ports that allow for the exchange of gases.
These are present in specialized branches of roots that are negatively geotropic and extend above the surface of muddy soil to allow plants' roots to absorb oxygen from the atmosphere.

Concepts Used:
Root
A Root refers to the vascular part of any plant which is pinpointed or discovered at the lowest level and is entirely responsible for connecting the plant with the soil. It absorbs water (H20), minerals, nutrients, etc., and further feeds the plant for its development. Roots are also responsible for acting as the repository for food and nutrients of the plant.

Characteristics of Roots:
- Roots are homogeneous in nature due to their potential to work towards producing similar organs like secondary or tertiary roots from the pericycle.
- Roots can be examined as positively Geotropic and Hydrotropic but negatively Phototropic.
Functions of Roots:
- The roots are in charge of providing a systematic connection to the different parts of the plant.
- It is also accountable for the storage of the reserved food material and the synthesis for the growth of the plant.
