Question

1) how do unicellular organism respire?
2) differentiate between inhaled and exhaled air.
3)how does the diaphragm help in breathing? ​

Answer 1

• Unicellular organisms do not breathe in the typical sense, but they respirate by allowing oxygen to enter the cell membrane through the process of diffusion. Because they are so small, they do not have the organs, pores and entryways to breathe like multicellular organisms.
• Inhalation is the process of taking in air containing oxygen, while exhalation is the process of giving out rich containing carbon dioxide. This is the basic process of breathing. Here one breath involves the one complete inhalation and exhalation.
• The diaphragm is a thin skeletal muscle that sits at the base of the chest and separates the abdomen from the chest. It contracts and flattens when you inhale. This creates a vacuum effect that pulls air into the lungs. When you exhale, the diaphragm relaxes and the air is pushed out of lungs.

Answer 2

Diffusion is the process by which unicellular organism inhale .

Human inhale Oxygen and exhale Co2 in generally .

In inhale diaphragm become enlarge when exhale diaphragm contract .

Contraction and enlargement of diagram helps in respiration as well store large amount of air .
