Detailed explanation-1: -Roots are the plant parts present below the soil. Roots help in anchoring the plant to the soil by placing it firmly in the soil. They also help to absorb water and minerals from the soil.

Detailed explanation-2: -Mosses are typically soft plants that grow in clumps or mats. Like other plants, they produce chlorophyll and undergo photosynthesis, but they do not have true roots. They instead have multicelled, rootlike appendages called “rhizoids, ” which anchor the plants and take in water and minerals.

Detailed explanation-3: -Thin rootlike structures called rhizoids anchor the moss and absorb water and nutrients from the soil.

Detailed explanation-4: -In mosses, the rhizoids have oblique crosswalls and are non-photosynthetic. Unlike the roots in plants, rhizoids do not absorb water or nutrients from the substrate; instead, their main function is to attach the plant to its substrate.

Detailed explanation-5: -The rhizoids of Chara species grow into the substrate where they play an important role in anchoring the plant.
