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.
name the organism which absorbs oxygen by diffusion
Cell Divisioncell reproduction & cell divisionCell division is the process in which it has as a role in the growth and repair of tissue in multicellular
Complex organism generally means multicellular, but in that category there are different levels of complexity. Sponges are multicellular, but don't have distinct tissue, for example. Generally, any living thing that you can see with your naked eye is extremely complex.
Peptidation is a protein synthesis inhibitor. Peptidation is a model based off of RNA selection in the cells of all multicellular organisms.
The base sequence of DNA carries all the information needed to code for proteins.

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.
It is possible in multicellular but not effective .

They obtain their oxygen by simple diffusion.
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.
because multicellular organisms cannot survive on diffusion alone. as a result, they need these mechanisms to transport nutrients and substances through the body
All waste products are removed, they may not go by diffusion alone.
ten multicellular organisms
There are many examples of multicellular organisms. Us humans are multicellular, animals are multicellular. Smaller organisms are unicells.
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.
Yes, fish are multicellular organisms
multicellular organisms begin as a single cell.
