Why is diffusion insufficient meet the oxygen requirements of multicellular organisms like humans?
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.
What else can I help you with?
Name the organisms that absorb oxygen by diffusion?
Small aquatic organisms like single-celled bacteria, protozoa, and some aquatic invertebrates absorb oxygen by diffusion through their body surface, since they have a high surface area to volume ratio which allows for efficient exchange of gases.
Which process has a role in the growth and repair of tissue in multicellular organisms?
Cell division is the process that plays a key role in the growth and repair of tissue in multicellular organisms. When cells divide, they can increase in number to promote tissue growth or help replace damaged or dead cells during tissue repair.
What are complex organisms?
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.
What does the diffusion of water mean?
The diffusion of water refers to the movement of water molecules from an area of high concentration to an area of low concentration. This process occurs naturally to achieve equilibrium and is important for processes like osmosis in living organisms.
How do single celled organisms get oxygen?
Single-celled organisms typically absorb oxygen directly from their environment through a process known as diffusion. Oxygen molecules move from areas of high concentration to low concentration, allowing these organisms to take in oxygen from their surroundings to support their metabolic processes.
Why is diffusion insufficient to meet the oxygen requirements of multicellular organisms like humans?
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.
Why is diffusion possible in unicellular organisms not in multicellular organisms?
It is possible in multicellular but not effective .
Why is diffusion insufficient to meet the oxygen requirement for multicellular organisms like human?
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.
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.
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.
Why can't all waste products be diffused by multicellular organisms?
All waste products are removed, they may not go by diffusion alone.
Types of multicellular organisms?
ten multicellular organisms
