отбирается фильтрами: Справочники и указатели In some classification systems this division is called Pyrrhophyta. There are approximately 2,000 species of dinoflagellates. Most have two flagella that lie perpendicular to one another and cause them to spin as they move through the water. Most have walls, or thecae, that are rigid and armorlike and sometimes take on fantastic shapes. The plates that make up these walls are actually located inside the plasma membrane rather than outside, as cell walls are. [ eng ] |
