What is a single layer of cells that can function in one or more of the following ways diffusion osmosis filtrationsecretion and absorption?

Simple squamous epithelium is a single layer of flat cells that is ideal for diffusion and filtration due to its thin structure, allowing for exchange of molecules. It can also function in osmosis, where water moves across the cell membrane, and in absorption and secretion processes, as seen in the lining of blood vessels and body cavities.


In the human body oxygen is absorbed by the lungs and nutrients are absorbed by the small intestine. In a single-celled organism this absorption directly involves the what?

In single-celled organisms, such as bacteria or protists, absorption occurs directly through the cell membrane. The cell membrane allows for the passage of oxygen, nutrients, and other molecules into the cell through processes like diffusion or active transport. This direct contact with the external environment allows single-celled organisms to efficiently obtain the necessary resources for survival and growth.

In the human body oxygen is absorbed by the lungs and nutrients are absorbed by small intestine. in a single celled organism this absorption diretectly involves the?

In single-celled organisms, such as amoebas, absorption of gases and nutrients occurs directly through the cell membrane via a process called diffusion. The cell membrane allows small molecules to pass through, enabling the organism to take in oxygen and nutrients from its environment. This process is essential for the cell's survival and energy production.
