show more I always thought that male chickens were called roosters, and female chickens are called hens.. I was just wondering if chicken is an umbrella term for both these animals? In other words, when we buy chicken in the super market, does it always come from a hen?n the market, you are eating hens when they are called fryers. Generally, roosters are not eaten, except in stews and some soups. Many chicken farmers just kill all male chickens that are born because there is no demand for them.
Gymnosperms. Gymnosperms are one of the two groups of seed plants. The flowering plants (angiosperms), are the other. In going from mosses and ferns to the seed plants, we see a very significant difference in plant life cycles. In mosses and ferns the propagating units for new individuals are spores.In the seed plants, gymnosperms and angiosperms, the propagating units for new individuals are seeds.Spores are single, haploid cells, and develop into gametophytes. major distinction we can make between seed plants (gymnosperms and angiosperms) and the non-seed plants (mosses and ferns) is that seed plants are heterosporous and non-seed plants are homosporous.
The Angiosperms (Flowering plants). are seed-bearing vascular plants. Their reproductive structures are flowers in which the ovules are enclosed in an ovary. Angiosperms are found in almost every habitat from forests and grasslands to sea margins and deserts.Angiosperms display a huge variety of life forms including trees, herbs, submerged aquatics, bulbs and epiphytes.The largest plant families are Orchids, and Compositae (daisies) and Legumes (beans).here are an estimated 352,000 species of flowering plants or angiosperms. You can also browse genera found in Angiosperms. View statistics at the bottom of the page.
