There are many different groups of phytoplankton species found in the world's oceans, but among the most common are diatoms and dinoflagellates. Most of the species featured on this site belong to one of these two groups. Dinoflagellates are both autotrophs and heterotrophs, they can get energy through both eating and photosynthesizing. Dinoflagellates are found all over the ocean, but do not contribute to ocean sediments.

CHARACTERISTICS OFDINOFLAGELLATES Dinoflagellates have two flagella. They spin in a top like motion. When disturbed, they glow causing the ocean to … 2018-09-14 Cell Characteristics Dinoflagellates are not members of the kingdom Plantae but rather are protists, and they have both plant and animal characteristics. Some species are autotrophic—in other words, they have their own chloroplasts and can produce their own sugars and organic materials through photosynthesis. Dinoflagellates: Characteristics, Examples & Classification. Worksheet.
They are a fairly large group, including photosynthetic, heterotrophic, free-living organisms, parasites, and symbionts. 2020-08-01 Dinoflagellates | Structure & Characteristics.

Early botanists classified dinoflagellates as a separate division of algae, which they named Pyrrophyta, after the Greek word ‘pyrr(h)os’ meaning fire. Later it was found that Pyrrophyta division includes many members which for the convenience of study were divided into dinoflagellates and cryptomonads.

General characters of dinoflagellates are as follows :
Dinoflagellates (Division or Phylum Pyrrhophyta) are a group of primarily unicellular organisms united by a suite of unique characteristics, including flagellar insertion, pigmentation, organelles, and features of the nucleus, that distinguishes them from other groups.

Series: Marine Biology BISAC: SCI039000. Marine dinoflagellates, one of the most important components in phytoplankton are receiving much attention owing to their toxicity. Dinoflagellates also have few or no nucleosomes associated with their DNA and a unique pattern of mitosis (Spector, 1984). Because these characteristics are so different from both eukaryotic and prokaryotic cells, a new intermediate kingdom, Mesokaryota, was once proposed for them (Dodge, 1965).

Dinokarya lack nucleosomes (Rizzo Amphiesma. The organization of the outer Dinoflagellates characteristics are as follows – Most dinoflagellates are marine planktons, but some are also found in freshwater. Their distribution depends on the pH level, temperature and depth of the aquatic ecosystem. Their flagella are responsible for locomotion and facilitate a spinning top-like motion.
Dinoflagellates are fascinating protists, mostly unicellular, distributed in environments ranging from the polar to tropical seas, hypersaline, coastal, estuarine and oceanic waters. There are about 2,377 dinoflagellate species recognized. They exhibit a great diversity of shape, size, biochemical composition and physiological characteristics. 2010-08-07 · There are roughly 2,000 known species of Dinoflagellata. They are unique organisms because although they are usually treated as plants, dinoflagellates assume some animal characteristics, such as preying on smaller organisms for food.
