Answer 1

Hello User..!!

Characteristics of Moss:-

1: Mosses have a rhizoid that absorbs water and all the nutrients from the soil.

2: They also have a radial symmetry.

3: Mosses do not have true leaves or stems

4: Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks.

Characteristics of Fern:-

1: It usually has one or more fronds that are attached to a rhizome.

2: They are tropical plants that can grow 60ft or more in height.

3: Ferns reproduce by seeds.

4: They also have roots known as rhizomes.

Characteristics of Agaricus:-

1: Agaricus is a genus of mushrooms.

2: It is the secondary or dikaryotic mycelium.

3:  It produces mushrooms basidiocarps year after year.

4:The basidiocarps arise as tiny, white apical swellings on the branches of    the underground mycelial strands called rhizomorphs.

Characteristics of Pinus:-

1: Pinus is the largest genus in the family Pinaceae.

HEYA MATE HERE IS UR ANSWER ❤

Characteristics-

MOSS -

Mosses have several characteristics that distinguish them from other bryophytes. Only mosses have a multicellular rhizoid, a root-like subterranean tissue that absorbs water and nutrients from the soil. Liverworts and hornworts have single celled rhizoids.

FERN -

✔Ferns are seedless vascular plants of humid tropics and temperate areas.

✔They constitute the largest living group of primitive vascular plants with over 10,000 species.

✔Plant body is a sporophyte.

✔The stem is underground rhizome in most of the ferns. 

AGARICUS -

1. The primary mycelium produced by the germination of basidiospores is of short duration. It consists of cells each with a haploid (n) nucleus (A).

1. The primary mycelium produced by the germination of basidiospores is of short duration. It consists of cells each with a haploid (n) nucleus (A).2. Soon as a result of hyphal fusions of compatible strains, a binucleate condition established in one of the cells of the primary mycelium..

PINUS -

✔The body is divided into stem, roots and needle-like leaves.

✔The stem is erect and cylindrical and is cov¬ered with bark.
