If mosses do not have true stems or roots, how do they get water through them so they can use photosynthesis?
A
from cell to cell
B
by xylem
C
by phloem
D
by drinking it
Explanation: 

Detailed explanation-1: -patens. 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-2: -They don’t have roots So without roots, some moss suck nutrients up through the rhizoids and others draw in moisture and minerals from rain and the water around them through their highly absorbent surfaces.

Detailed explanation-3: -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-4: -Moss absorbs and spreads water directly into its cells through osmosis. This is one reason mosses do not grow large foliage like other plants. They must allow water to penetrate the body of the plant and reach the various cells. Mosses do not have roots or a vascular system to transport water.

Detailed explanation-5: -No, mosses do not have true roots, stems, or leaves. Mosses attach themselves to the surfaces on which they grow using small, clinging structures called rhizoids. While they help attach the plant to surfaces, they do not draw in or transfer moisture and nutrients to the plant the way true roots do.
