Amount of Unicellular and Multicellular OrganismsMore than 1 and 1|2 (one half) million kinds of organisms have been identified. That number is small compared to the estimated number of unicellular organisms that exist and have not been identified. Scientists estimate that there are more than 1 billion kinds of unicellular organisms!
Unicellular organisms and multicellular organisms both contain the characteristics of life. Furthermore, both unicellular organisms and multicellular organisms follow the same genetic code and even contain the same organelles.
Multicellular organisms work like an assembly line, and if one part of a multicellular organism dies, it can be replaced, but if a part of a unicellular organism dies, the entire organism dies. The assembly line process is called specialization.
The availability of water is one of the most important factors that determines the number and kinds of organisms that live in an area.
No, a gamete has half the number of chromosomes as compared to the organisms body cells.

The main distinction between unicellular and multicellular is the number of cells. Unicellular organisms survive on a single cell while multicellular means that they need a number of cells to survive.
Unicellular organisms and multicellular organisms both contain the characteristics of life. Furthermore, both unicellular organisms and multicellular organisms follow the same genetic code and even contain the same organelles.
They both have the basic unit of life, the cell. Bacteria and amoeba are examples. They are different because multicellular organisms are bigger because of the number of cells they have. They also have cells that are similar in size and shape that work together as tissues and tissues that form organs and organ systems.
The difference between unicellular and multicellular lies in the number of cells. Unicellular refers to simple organisms with only one cell while multicellular refers to complex organisms with many cells.
Multicellular organisms work like an assembly line, and if one part of a multicellular organism dies, it can be replaced, but if a part of a unicellular organism dies, the entire organism dies. The assembly line process is called specialization.
No, there are many unicellular organisms among eubacteria, archaebacteria, and protists. These microbes are so great in number that the number of microbial cells in and on your body is greater than the number of your own cells.
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.

Sounds as if you are describing protists.A number of algae like Clamydomonas, volvox, oedogonium and bryophytes like riccia, marchantia etc.

Pneumonia is an illness (inflammation of the lung) and can have a number of potential causes. Most common are infections by viruses (e.g. influenza virus or adenovirus) or bacteria (e.g. Streptococcus pneumoniae). These are unicellular organisms. However in some cases pneumonia can be caused by parasites like the hookworm. These are multicellular.
