Why is diffusion insufficient to meet the oxygen requirements of multicellular organisms like humans?

∙ 11y ago
In single-celled organisms the entire surface of the organisms is in contact with the environments for the diffusion of substances. In multi-cellular organisms all the cells may not be in direct contact with the surrounding environment. So simple diffusion will not meet the requirements of all the cells.

Do multicellular organisms develop?
No
Is a planarian unicellular or multicellular?
Planaria are multicellular organisms
True or false in multicellular organisms cilia and flagella are the major means of locomotion?
It is true that in multicellular organisms cilia and flagella are the major means of locomotion. Locomotion is one of the characteristics of living organisms.
How does a multicellular organism maintain homeostasis?
The cells of multicellular organisms become specialized for particular tasks and communicate with one another to maintain homeostasis. Specialized cells in multicellular organisms are organized into groups. A tissue is a group of similar cells that performs a particular function.
In what kinds of organisms is the cell specialization a characteristic?
Either multicellular or unicellular organisms. By the way are you using Prentice Hall Biology California because many of your questions are from the book? prentice hall florida actually

Why is diffusion possible in unicellular organisms not in multicellular organisms?
It is possible in multicellular but not effective .

How do multicellular organisms breathe?
They obtain their oxygen by simple diffusion.
Why do you need various system in human body?
As we are multicellular organism so we need different types of organs to perform all functions of our body. In multicellular organisms, all cells may not in the direct connect with the surrounding environment . Therefore, the diffusion is insufficient to meet the oxygen requirements in them. Instead, they need specialized organs for breathing and exchange of gases like heart ,lungs etc.
Transport system needed multicellular organisation?
because multicellular organisms cannot survive on diffusion alone. as a result, they need these mechanisms to transport nutrients and substances through the body
Types of multicellular organisms?
ten multicellular organisms
Why can't all waste products be diffused by multicellular organisms?
All waste products are removed, they may not go by diffusion alone.
All multicellular organisms are called?
There are many examples of multicellular organisms. Us humans are multicellular, animals are multicellular. Smaller organisms are unicells.
What transport mechanism do one celled colonial and simple multicellular organisms rely on?
These organisms use simple diffusion as a transport mechanism.This is possible because of the small size of the organisms. Diffusion is effective over small distances but as size increases it becomes less and less efficient.
Are fish multicellular organisms?
Yes, fish are multicellular organisms
How do multicellular organisms begin?
multicellular organisms begin as a single cell.
