It is covered by 1 or 2 thin integuments having a narrow micropyle. All the species of plants come under the category of the plant kingdom. Gymnosperms (Nonflowering seed plants): The gymnosperms are seed producing land plants. Gymnosperms are often found in temperate forests and boreal forest biomes. Example- Equisetum, (iv) Class 4: Pteropsida. The plant body of liverworts is thalloid and dorsiventral in structure, but mosses have upright slender axes bearing spirally arranged leaves. Most of them are hydrophytes, i.e. These are not to be confused with algae that look like plants but arent, such as seaweed. The leafy stage develops from the secondary protonema as a lateral bud in mosses. India is rich in the flora with respect to endemic plant species, the distribution of which is determined as 5725 angiosperms (of 17,500), 10 gymnosperms (of 64), 193 pteridophytes (of 1022), 678 . Gymnosperm is derived from the Greek words Gymno, which means naked, and Sperma, which means seed.

How would you distinguish between monocots and dicots? Summary Comparison Chart What are Angiosperms? Whereas, the flowers are the reproductive entity in angiosperms. The reproductive organs are usually borne in cones on which spores are spirally arranged. An ovule is covered by three layers of integuments of wide miropyle. Later they generate the male gamete that fertilizes with the female gamete to give rise to a zygote. The two remaining nuclei move to the centre to make a diploid nucleus. Angiosperms, are also known as flowering plants and having seeds enclosed within their fruit. The significant difference between bryophytes pteridophytes gymnosperms and angiosperms are the seed-bearing capacity. Plants contain chloroplast and chlorophyll pigment, which is needed for photosynthesis. Seeds are used instead of spores to propagate these plants, which is an improvement over the pteridophyte model because seeds last considerably longer than spores. During fertilisation in gymnosperms, male gametes have to come through pollen tube, hence there is no direct access of male gametes to female gametes. A zygote is formed after the fertilization of male and female gametes. Male gametes of gymnosperms are generally non-motile(multi-flagellated, motile sperms are present only in cycads and ginkgos). Seeds develop on the megasporophyll and fruits are never formed. The area of vascular tissues is more than the cortex and pith. It develops into protonema which gives rise to male and female gametophytes.
