Explanation: 

Detailed explanation-1: -Unlike most other plants, mosses don’t have roots. Instead they have rhizoids, which are small hairlike structures. Their main function is anchoring the plant to rock, bark or soil.

Detailed explanation-2: -Rhizoids grow out of the base of the gametophyte, which is the section of the plant that is not used for reproduction and consists of the leaf-and stem-like structures as well as the rhizoid. This shows the rhizoids in moss located at the base of the gametophyte.

Detailed explanation-3: -Rhizoids are protrusions that emerge from the bottom epidermal cells of bryophytes. Rhizoids can be single-celled or multicelled root-like structures. Non-vascular plants such as bryophytes have thallus-like plant bodies that are prostrate or upright.

Detailed explanation-4: -Moss capsule. (Science: botany) A moss capsule is a part of the moss located at the tip of stalk that contains pollen. Last updated on July 23rd, 2021.
