Current Question (ID: 11912)

Question:
$\text{Which of the following organisms are known as chief producers in the oceans?}$
Options:
  • 1. $\text{Dinoflagellates}$
  • 2. $\text{Diatoms}$ (Correct)
  • 3. $\text{Cyanobacteria}$
  • 4. $\text{Euglenoids}$
Solution:
$\text{Protista includes all unicellular eukaryotes, irrespective of their mode of nutrition. Protistan protists are popularly called as protistan algae, consisting the major portion of the phytoplankton.}$ $\text{Diatoms are the golden brown photosynthetic protists and called as Chrysophyta (including both diatoms and desmids). They are both aquatic and terrestrial. Some are marine and supports much of the marine life.}$ $\text{They are basically unicellular but may form pseudofilaments and colonies, lacking flagella except in the reproductive stage.}$ $\text{They may be free-floating, remaining a floats on the surface of water due to the presence of light weight lipids.}$ $\text{Reference: PAGE 20, XI NCERT}$
