Plant kingdom - A. Cryptogamae (seedless) B. Phanerogamae (bearing seed).

Crytogamae - A. Thalophyt B. Bryophyt C. Pteridophyt.

Thalophyt - No root, stem, leaves, cell wall made up chitin.

Two type: A. Algae B. Fungi.

Bryophyt - Chlorophyllous, autotrophic, embryopand atracheophytic cryptogams.

Pteridophyte - Have vascullar tissue, have root stem leaves.

Phanerogamae - A. Gymnospern (non flowering, pollination thru air) B. Angiosperm (flowering).

Angiosperm - A. Autrotrophic (prepare own food) B. Parasite (expend on other food).

The gymnosperms are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes. The term "gymnosperm" comes from the Greek composite word meaning "naked seeds", after the unenclosed condition of their seeds. Their naked condition stands in contrast to the seeds and ovules.

Yeah, gymmnosperms are of primitive type early plants on earth other than bryophytes. They have arisen in early time of evolution. They have xylem and phleom but they have less dense wood in comparison to angiosperms.

Gymnosperms is also refer to as fruitless flowering plants. It grows large trees but it does not require so much of water it usually grow in hilly regions so because it is used for timber.

Gymnosperms plants having no seed inside a fruit ie its seeds are naked and spread widely by agent air, water, animal, human etc.

Generally it grows in hilly and foothill areas.

Gymnosperm are generally medium size tree or tall trees or shrubs. Gymnosperm means seed naked plant in which the ovules are not enclose by any overy wall & remain exposed.

Gymnosperm are generally medium size tree or tall trees or shrubs. Gymnosperm means seed naked plant in which the ovules are not enclose by any ovary wall & remain exposed.

Gymnosperms are characterized by the presence of naked ovules, born unprotected on the surface of megasporophylls. Some examples are cycas, pinus, and ephedra etc.

Binomial nomenclature is a non flowering plants, so the mentioned above is a non flowering plant, gymnosperm is a correct answer.

Monocotyledons and dicotyledons entirely belong to some other characteristics so these 2 are not correct answers.
