Planktonic algae algae composed of only one cell, it is also known as marine unicellular algae. Such organisms are a group with chlorophyll, photosynthesis can be, and the production of organic matter autotrophic organisms. They are the most important marine primary producers, but also farmed fish, shrimp, shellfish bait. Planktonic algae has been recorded in 1817 kinds of Chinese sea.
Planktonic algae athletic ability is very weak, only to drift floating or suspended in water for very weak float. They have to adapt to life in a variety of floating body, so that buoyancy increases. For example: some planktonic algal cells give birth around the circle bristle; some length with long spines or protrusions, these appendages increases the contact surface with water, can generate a lot of stability, so that it can float in Some form groups to facilitate the expansion of the surface area of floating, and their own individual small floating life is also a very good form of adaptation; light of the surface water.
Planktonic algae body generally only thousandths of a millimeter in diameter, visible only under a microscope to look like them, but its shape their own characteristics, is almost a one way. Most of them are single cells, but also many of the single-cell population combined with spindle-shaped, fan-shaped, star-shaped, oval, ovoid, cylindrical, and dendritic. |
