Question

How do unicellular organisms perform all the necessary functions that multicellular organisms perform using specialised organs?​

Answer 1

Unicellular organisms perform its function by the organelles of the cell.

Explanation:

• The functioning of a unicellular organism is not as complex as a multicellular organism.

• The organelles of a single cell that the unicellular organism possesses are enough to perform the simple tasks of the unicellular organisms.

• Also, the structure of a unicellular organism is not as complex as the multicellular organism, hence the single cell is able to perform the necessary functions for survival.

Answer 2

Answer:

All the life activities of a unicellular organisms are carried out by the individual cell and its organelles. Multicellular have differentiated cells that form the different tissues and organs (liver, heart, vessels etc) that carry out different functions for the survival of the organism
