What are the diatoms?

Diatomas are unicellular algae, which form a clear and beautiful cell walls of silica. They are widely distributed in the upper layers of the world's oceans and can also be found in fresh water or humid environments such as the underside of the plants. There are more than 16,000 recognized diatoma species, and many others are constantly identified. Because diatoms are so abundant, they form an important part of the pelagic food chain and serve as a source of food for most animals in the ocean, either directly or indirectly. They also have very limited mobility; Some types of diatoms are capable of slow excellent movement, but others rely on the streams that transmit them around the ocean. When they die, the diatoms immersion on the bottom of the ocean and contribute to the sludge layer that forms the seabed. In parts of the world where there are no longer oceans, this sludge forms a fossilized layer of the Earth, the substances used in production and as a natural pesticide.

All diatoms belong to the Bacillariophyta class , although some biologists question their exact classification. They are generally considered to be protisp. They have a simple internal structure and at some point in their life cycle, the sophistication excrete silica and form strong cell walls. The cell walls are in the form of two same halves that are blocked, like half of the clam or shell. Silicon oxide is formed in a radial or bilateral symmetrical pattern and is often extremely complex and stunning to look at. The diatoms are reproduced asexually and are divided to create more sills.

In many cases, the diligence floats itself through the ocean. In other diatoms, huge colonies of individuals are connected in different ways. Unique organisms are sometimes cooked sea jewelry due to their distinctive cell walls. Many students starting biology look at the diatoms under the microscope to learn an incredibleDetails that can be found in microscopic organisms. Any seawater sample from the surface of the healthy ocean will contain a number of diatoms in a number of shapes that you can look under the microscope.

Diatomas are similar to dinoflagelates, another large class of the protists inhabited by the ocean. Dinoflagelates are more capable of moving than most of the diatoms, using whip shoulders. Some dinoflagetes also form symbiotic relationships with other organisms. Both were identified and described by early biologists and numerous brochures demonstrating the forces of the microscope used by the drawings of these slight organisms as illustrations.
