<span>Spirogyra, otherwise known as pond silk, is a type of algae that can be found in bodies of freshwater. The cells are long, unbranched, and cylindrical, being much longer than they are wide. There is no distinction between the basal and distal end, and they connect to each multiple times over to create the "silk" they are seen as; they also can reproduce sexually and asexually. Each cell has one nucleus and a cell wall composed of pectin surrounded by cellulose. Inside each cell is a very distinct spiraling shape of green, being chloroplast strands. It is these shapes for which the cells are named.</span>

Although tube worms cannot produce their own food, they often thrive around these underwater vents. They are able to survive because inside the tube is the trophosome, an organ that contains millions of bacteria in symbiotic relationship with the worm, which are responsible for feeding these creatures that do not have any type of digestive system or visual organs, as they live in the most absolute darkness.

<span>Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. (Domesticated) animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as (varieties), cultigens, or cultivars. Two purebred animals of different breeds produce a (crossbreed). Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. </span>
