(3) Yeast is photosynthetic protist
(4) Keiselgurh forms by cell wall of
dinoflagellates.​

Answer 1

Answer:

Hey, I'll try to answer you question, no worries, feel free to point me out if I'm wrong or didn't understood something. So, here we go...

Dinoflagellates:-

They are mostly marine and photosynthetic

They appear in different colors like red, green, yellow etc depending on their pigments

Cell wall consists of thick cellulosic plates

Locomotion is by two flagella, one longitudinally and the other transverse

They also release toxins which can kill marine beings if present in high quantities

Example: Gonyaulax (red dinoflagellate)

Its rapid multiplication leads to Red tides
