Unicellular organisms develop ways to maximize efficiency of processes by evolving structures to maximize surface area.

|
Multicellular organisms develop ways to maximize efficiency of processes by using ATP to force essential nutrients into their bodies.
|
|
|
Multicellular organisms must keep important structures within their body so that nutrients are not lost into the environment.

Detailed explanation-1: -The villi of the small intestine are similar to the alveoli in that they tremendously increase the surface area.
Detailed explanation-2: -Alveoli: Alveoli are the tiny air sacs present in the lungs that allow the rapid exchange of gases. Nephrons: Nephrons comprise glomerulus and tubules through which glomerular filtrate passes. Functioning of alveoli in the lungs and nephrons in the kidneys: Alveoli.
Detailed explanation-3: -Both the alveoli in the lungs and villi in the small intestine are in direct contact with blood capillaries. this enables gaseous exchange in the lungs via alveoli, and absorption of nutrients in the small intestine via villi. Also, both increase the surface area of absorption.
Detailed explanation-4: -Alveoli are tiny balloon-like structures present inside the lungs. Nephrons are tubular structures present inside the kidneys. The walls of the alveoli are one cell thick and it contains an extensive network of blood capillaries. Nephrons are made of glomerulus, bowman’s capsule, and a long renal tube.
