Simple diffusion has limitations in organisms like amoebas because it is reliant on the concentration gradient and does not require energy input, limiting the movement of substances against a gradient or in areas of low concentration. Amoebas may not efficiently absorb necessary nutrients or expel waste in areas of low concentration due to the passive nature of simple diffusion, which affects their overall metabolic processes and growth.

How does the amoeba obtain oxygen and carbon dioxide?
Amoebas obtain oxygen through diffusion across their cell membrane from their environment. Carbon dioxide is similarly exchanged through diffusion, with waste carbon dioxide being eliminated from the cell in the same manner.
What is the breathing organ of Amoeba?
Amoeba does not have specific breathing organs like lungs or gills. Instead, it relies on simple diffusion of gases through its cell membrane to exchange oxygen and carbon dioxide with its environment.
Is simple diffusion the net diffusion of a solvent?
no
What is the transport that moves a solute down the concentration gradient?
Simple diffusion
A person blows air molecules in balloon by forcefully exhaling is simple diffusion?
No, blowing air into a balloon by forcefully exhaling is an example of active transport, not simple diffusion. The process involves the use of energy to move air molecules against a concentration gradient into the balloon. Simple diffusion, on the other hand, is a passive process where molecules move across a membrane from an area of high concentration to an area of low concentration.
How does the amoeba obtain oxygen and carbon dioxide?
Amoebas obtain oxygen through diffusion across their cell membrane from their environment. Carbon dioxide is similarly exchanged through diffusion, with waste carbon dioxide being eliminated from the cell in the same manner.
What is the breathing organ of Amoeba?
Amoeba does not have specific breathing organs like lungs or gills. Instead, it relies on simple diffusion of gases through its cell membrane to exchange oxygen and carbon dioxide with its environment.
An example of passive transport process is?
One example of a passive transport process is simple diffusion, where molecules move across a membrane from an area of higher concentration to an area of lower concentration without the need for energy input.
What is a simple living thing?
An Amoeba.
Are osmotically active substances simple diffusion or active transport?
simple diffusion.
Is simple diffusion the net diffusion of a solvent?
no
What are the 3 types of diffusion?
simple diffusion, osmosis and facilitated diffusion.
Why can amoeba have exchange of gases through its body surface?
Amoebas are small single-celled organisms with a large surface area-to-volume ratio, allowing for efficient gas exchange through their body surface by simple diffusion. This surface area contact with the environment facilitates the exchange of oxygen and carbon dioxide, enabling them to meet their metabolic needs.
How does gases enter and leave capillaries?
Simple diffusion.
What happens in simple diffusion?
In simple diffusion, a substance passes through a membrane without any outside intermediary. The rate of diffusion is based on the force exerted..
How does facilitated diffusion from simple diffusion?
It doesn't. (answer by RRU member Cyrem)
Why is the amoeba considered a simple organism?
It's a single cell.
