From Wikipedia, the free encyclopedia. Cogeneration (also combined heat and power, CHP) is the use of a heat engine or a power station to make both electricity and useful heat at the same time. Conventional power plants emit the heat created as a byproduct of electricity generation into the environment through cooling towers, as flue gas, or by other means.
Plants divide into two groups: plants lacking lignin-impregnated conducting cells (the nonvascular plants) and those containing lignin-impregnated conducting cells (the vascular plants). Living groups of nonvascular plants include the bryophytes: liverworts, hornworts, and mosses.Vascular plants are the more common plants like pines, ferns, corn, and oaks. The phylogenetic relationships within the plant kingdom are shown in Figure 1.he sporophyte phase produces spores by meiosis within a sporangium. The gametophyte phase produces gametes by mitosis within an antheridium (producing sperm) and/or archegonium (producing eggs). These different stages of the flowering plant life cycle are shown in Figure 4.
