Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Mosses and their relatives grow close to the ground because they do not have:
A
vascular systems
B
root systems
C
reproductive systems
D
None of the above
Explanation: 

Detailed explanation-1: -Mosses and their relatives are seedless nonvascular plants, they are called bryophytes. They lack a vascular system (plumbing system) to move water and nutrients throughout the plant. For this reason, they grow close to the ground to absorb water and nutrients.

Detailed explanation-2: -Mosses and liverworts are small, primitive, non-vascular plants. They lack the conductive tissue most plants use to transport water and nutrients. Instead, moisture is absorbed directly into cells by osmosis.

Detailed explanation-3: -Mosses are non-vascular plants with about 12, 000 species classified in the Bryophyta. Unlike vascular plants, mosses lack xylem and absorb water and nutrients mainly through their leaves.

Detailed explanation-4: -They don’t have roots 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-5: -Mosses absorb their water and nutrients directly into their bodies, not through their “roots". Instead of roots, they have rhizoids, which serve to stabilize the moss but do not have a primary function in water and nutrient absorption. They lack a vascular system both in their rhizoids and in their above-ground parts.
