Detailed explanation-1: -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-2: -Nonvascular plants are plants that do not have any special internal pipelines or channels to carry water and nutrients. Instead, nonvascular plants absorb water and minerals directly through their leaflike scales. Nonvascular plants are usually found growing close to the ground in damp, moist places.

Detailed explanation-3: -Antheridia and archegonia may occur on the same gametophyte or on separate male and female gametophytes. Male gametes in the nonvascular plants have motile sperm and are dependent on water for dispersal to the female gametes, which are nonmotile eggs retained in the archegonia on the gametophyte.

Detailed explanation-4: -The non-vascular plants grow in moist environments. It is due to lack of vascular tissue that requires to maintain close contact with water to prevent desiccation.

Detailed explanation-5: -The tissues of rhizoids can absorb water directly just like the other tissues of nonvascular plants. Some types of bryophytes have leaf-like structures that aid in the process of photosynthesis. These leaf-like structures absorb water and nutrients directly from the plant’s environment, just like a sponge.
