Question

vi) What are the disadvantages of multi cellularity?​

Answer 1

Answer:

The disadvantages of multicellularity: A multicellular organism needs more food than unicellular organsisms because it needs more energy. In multicellular organisms, cells are organized into tissues and tissues are further organised into organs. So, if one organ fails, then whole organism can fail.

Answer 2

Answer:

Thee disadvantages of multicellularity are:

• Specialized cells often lose the power of division, so that injury is not repaired e.g., nerve cells.
• the Regeneration ability of multicellular organisms decreases with specialization.
• Specialized cells may lose vital functions to carry out specific activity e.g., RBCs, sieve tube cells.
