Which of the following statements is correct ? (1) Fusion of two cells is called Karyogamy (2) Fusion of protoplasms between two motile on non-motile gametes is called plasmogamy (3) Organisms that depend on living plants are called saprophytes (4) Some of the organisms can fix atmospheric nitrogen in specialized cells called sheath cells

Correct option:(2)
Solution:

  • In some blue-green algae specialised cells called heterocyst fixes atmospheric nitrogen into ammonia.
  • Fusion of two nuclei is called Karyogamy.
  • Organisms that depend on living plants are parasites, saprophytes grow on dead material.
  • Fusion of protoplasts of two cells is called plasmogamy.
