Question

Is the following statement correct? If it is wrong, correct the statement Statement: “Unicellular organisms do not respire, only multicellular organisms respire”

Answer 1

Respiration in organisms:

1. The given statement is wrong, as all the species or organisms respire.
2. Respiration occurs in both single and multicellular organisms. Every live cell engages in cellular respiration.
3. In contrast to multicellular organisms, unicellular organisms have a separate "breathing" system.
4. Respiration is a metabolic process in which an organism's living cells use oxygen to obtain energy (in the form of ATP) and release carbon dioxide as a byproduct of the oxidation of complex organic molecules.
5. The respiration of unicellular organisms can be either aerobic or anaerobic. They lack any breathing apparatuses for breathing. They breathe by diffusing air across their skin's surface.
6. However, in multicellular organisms, breathing is a far more intricate process that involves a unique respiratory system that acts as a bridge between the cells and the outside environment.

Correct statement: All organisms i.e. both unicellular and multicellular organisms respire.
