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.
Angiosperms vs. Gymnosperms. Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary (usually a fruit), while gymnosperms have no flowers or fruits, and have unenclosed or ânakedâ seeds on the surface of scales or leaves. Gymnosperm seeds are often configured as cones. The characteristics that differentiate angiosperms from gymnosperms include flowers, fruits, and endosperm in the seeds.
