The majority of fish reproduce by spawning, a process in which the female and male fish release eggs and sperm simultaneously in a protected environment with or without a complex courting ritual. Some spawners build nests to guard the fertilized eggs.Know More
Apart from building a nest, some spawners carry their embryos and their young around with them, while some, like the substrate spawners, scatter the eggs in the environment and do not guard the eggs or their young after spawning.
Live-bearing fish, which make up about 1 percent of all known fish species, mate to reproduce. The male inseminates the female through a modified fin called a gonopodium. The female livebearer stores the male's sperm and produces several broods of young fry, or newborn fish, from this single insemination.Learn more about Biology
Goldfish mate by spawning. The female releases her eggs into the water, and the male releases his sperm to fertilize the eggs. Goldfish reach sexual maturity at approximately 1 year of age.Full Answer >
Photosynthesis is a process that allows plants to harvest energy in sunlight and store it chemically, by producing sugars. Sugars hold energy in their molecular bonds; when the plant breaks down these bonds, energy is released that the organism can then use. Although green plants are the most famous photosynthesizing organisms, some bacteria, algae and protists carry out the process as well.Full Answer >
Platies are livebearing fish, and they breed by spawning. In spawning, male fish release gametes directly into the water near the female fish, directing the flow of gametes via their specialized anal fin. Male fish have narrow fins that help move gametes toward the inside of the female whereas female fish have broad fins. Females can store gametes within their bodies, releasing up to six broods after a single mating.Full Answer >
The female gamete is called the egg or ovum. The female gamete is fertilized by the male sex cell, called the sperm, to begin the process of reproduction.Full Answer >
