Question

In hydrophytes plants, water and salts are absorbed by
A. Root
B. Leaves
C. Stem
D. Outer layer of plant

Answer 1

Hint:
Before we proceed into the problem, it is important to know the definitions of the hydrophytes plants, water and salt are absorbed.
Those plants that have adapted to growing in the low-oxygen (anaerobic) circumstances brought on by prolonged saturation or flooding are known as wetland plants, hydrophytes or "water-loving" vegetation.
Water-dwelling plants are known as hydrophytes. They might be floating or submerged. Hydrophytes' roots are not very well formed.
Through surface exchange with the epidermis, they take in water and minerals.

Complete step by step answer:
Hydrophytes plants are plants growing in water. In these plants, roots are poorly developed and absorption occurs through the outermost surface of plants.
The mechanism of diffusion allows the root to take up mineral salts. Ions are what is absorbed when it comes to inorganic salts. Aquatic plants are referred to as hydrophytes. While trap, lotus, and other species have most of their bodies partially buried in the water, Hydrilla, Valisineria, and other species remain entirely submerged in the water. Crowfoots, sedges, and water lilies are some further significant aquatic plants.
Therefore, hydrophytes plants absorb water, and salts through the outer layer of the plant.

Option ‘D’ is correct

Note:
Plants that live completely or partially submerged in freshwater are known as hydrophytes. They require sophisticated methods to drain extra water from their cells.
The inability to retain water, flat leaves that make it easier to float on the water's surface, thin, feathery roots, and air sacs that help with flotation are some traits of hydrophytes.
Many of the wetland habitats in High Park are home to a variety of hydrophytes.
