A gene is a segment of DNA that encodes function. A chromosome consists of a long strand of DNA containing many genes. A human chromosome can have up to 500 million base pairs of DNA with thousands of genes.he total complement of genes in an organism or cell is known as its genome, which may be stored on one or more chromosomes. A chromosome consists of a single, very long DNA helix on which thousands of genes are encoded. The region of the chromosome at which a particular gene is located is called its locus.
Yes. Even the plants and algae that are completely under the surface are exposed to enough sunlight to conduct photosynthesis. Shoreline plants and partially submerged plants are included in water biomes, and these, of course, photosynthesize.
Photosynthesis is a chemical process that occurs in many forms of bacteria and virtually all plants, including aquatic plants and algae. Using just three simple ingredients (carbon dioxide, water, and sunlight) plants and bacteria are able to make their own food.lants, including aquatic plants, produce oxygen, and they also use oxygen. Here's how these processes work: During a sunny day, dissolved oxygen in water is generally plentiful because photosynthesizing algae and aquatic plants are constantly releasing it into the water.
