  1. Cryptogamy

  2. Schizogamy

  3. Autogamy

  4. Conjugation

Show answer
Correct Option: B
Explanation:

Schizogeny is the method of reproduction in which production of a sexual individual from an asexual form usually by fission.

Cryptogamy involves new individuals with spores without the formation of seeds or flowers.
Autogamy is a type of reproduction in which the production of offspring is done by the fusion of two gametes from the same individual.
Conjugation is the process of reproduction in which the genetic material is transferred between two cells by a direct cell to cell contact.
So the correct answer is yes 'Schizogamy'.

  1. Euglena

  2. Noctiluca

  3. Forminiferans

  4. Diatoms

Show answer
Correct Option: B
Explanation:

Noctiluca scintillans belongs to class Flagellata of phylum Protozoa. It is the most common cause of bioluminescence in the ocean. Because of this, it is also called sea sparkle. It produces light throughout the cytoplasm by luciferin- luciferase reaction.

Hence the correct option is B.
