Question

Differentiate between chrysophytes and dinoflagellates

Answer 1

dinoflagellates are a large group of flagellate protists that can constitute the phylum dinoflagellate. most are marine plankton,but they are common in fresh water habitats.
chrysophytes re common microscopic chromists in fresh water some species are colorless,but the vast majority are photosynthesis. 

Answer 2

Chrysophytes:-

1-This group includes diatoms and golden algae (desmids)

2-They are found in fresh water as well as in marine environments.

3-They are microscopic and float passively in water currents (plankton).

4-Most of them are photosynthetic.

5-The walls form two thin overlapping shells. The walls are embedded with silica and thus walls are indestructible.

_________________________

Dinoflagellates (Division-Pyrrophyta)

1-This is a well defined group of unicellular,golden-brown photosynthetic organisms.

2-Most of them are marine but some occur in fresh water.

3-Nutrition of dinoflagellates is mainly holophytic or photosynthetic. However, some of them are saprobic, parasitic, symbiotic or holozoic.

4-Some dinoflagellates are phosphorescent and make sea surface glow.in dark.

5-The cell wall of dinoflagellates,if present,is composed of a number of plates are made up of cellulose.They usually posses two flagella.
