The Correct Option is B

Solution and Explanation

Root cap is a thimble-shaped or cap-like parenchymatous multicellular strudure which covers the root meristem. The cells of the root cap secrete mudlage. The latter lubricates the passage of root through the soil. Without it, the tender root would be unable to penetrate the hard soil. Cells of the root cap also possess starch grains. Another fundion of the root cap is the protection of the root meristem from fridion of the soil partides. In the process, its outer cells are continuously peded off and replaced by new cells formed from root meristem. In floating aquatic plants the root apices possess loose finger glove-like coverings called root pockets e.g., Lemna, Pistia, Eichhomia. Root pockets fundion as balancers. The root system in hydrophytes is feebly developed and root cap and hairs are absent. In hydrophytes the root system is fundioning chiefly as anchors and a large part of the absorption takes place through the leaves and stems.

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:

  1. Roots are homogeneous in nature due to their potential to work towards producing similar organs like secondary or tertiary roots from the pericycle.
  2. Roots can be examined as positively Geotropic and Hydrotropic but negatively Phototropic.

Functions of Roots:

  1. The roots are in charge of providing a systematic connection to the different parts of the plant.
  2. It is also accountable for the storage of the reserved food material and the synthesis for the growth of the plant.
