HORTICULTURE

Detailed explanation-1: -Bryophytes like mosses are small as these are nonvascular plant having only few water conducting strands in central stem. Smaller size makes them rely on diffusion for movement of water in and out of the plants and to use water as a medium for sperm transfer.

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 essentially non-vascular, which means they lack any internal vascular tissues to transport water and nutrients, or at least those tissues are poorly developed. This is why mosses are so small! They don’t have the rigid internal structures that would allow them to grow taller like vascular plants.

Detailed explanation-4: -► Bryophytes are small because they lack vascular tissue, which is specialized for conducting water. Bryophytes display alternation of generations: 0 ⚫ Gametophytes produce eggs in archegonia and sperm in antheridia. Sperm and egg cells fuse to produce a diploid zygote.

Detailed explanation-5: -Nonvascular plants are very small because their lack of a vascular system means they do not have the mechanics required for transporting food and water far distances. Another characteristic of nonvascular plants that sets them apart from vascular plants is that they lack roots.
