What is the difference between unicellular & multicellular organisms? What are the major different between unicellular & multicellular organisms? What is the comparison between unicellular organisms & multicellular organisms?
Unicellular organisms & Multicellular organisms:-
In this article we will discuss about the unicellular organisms & multicellular organisms:-(1) what are the unicellular organisms & general character of the unicellular organisms (2) what are the multicellular organisms & the general character of the multicellular organisms.

- The general character of the multicellular organisms.
Every living organisms are composed of the cells. The number; these are classified into 2types of categories. These are:-
- Unicellular organisms
- Multicellular organisms
The difference between unicellular organisms & multicellular organisms are the numbers of cells.
Unicellular organisms:-
The unicellular organisms are made up of a single cell. These are invisible in the nacked eyes & cell types are prokaryotic & eukaryotic cells. The unicellular organisms are life span is short and they oldest life forms evolved 3.8-4 billion years ago. The unicellular organisms are generally different types like unicellular fungi, protozoa & bacteria; they are famous to know for asexual reproduction.
General characters of the unicellular organisms:-
- Unicellular organisms are composed of a single cell ; so it’s know as single cellular organisms.
- The unicellular organisms has simple body organization.
- Life span of the unicellular organisms is short.
- It has include both eukaryotic & prokaryotes.
- This organisms is reproduction by asexual reproduction.
- These organisms are cell differentiation is absent .
- The unicellular organisms are microscopic organisms, they are only visible in micro scop.
- The total cell of unicellular body is exposed to the environment.
- These organisms are injury is lead to the death.
- These are operational efficiency is low.
- The unicellular organisms oldest life form evolution 3.8-4 billion years ago.
- The unicellular organisms are small in size.
- The unicellular organisms is irregular in shape.
- Protozoan, bacteria, unicellular amoeba etc. Are the examples of unicellular organisms.
Multicellular Organisms:-
These organisms are made of more than one cell are called multicellular organisms.
A multicellular organisms are made up of more than one cell. These are know as multicellular organisms. These organisms are bigger in size & very complex structure. Animas, plants, human beings, birds & insects are the examples of multicellular organisms.
The multicellular organisms are many biological responsibility like digestion, respiration, circulation & sexual reproduction to a particular organs like lungs, skin, heart, stomach, sex organs etc.
General characters of the multicellular organisms:-
- The multicellular organisms are made up of one or than more cells; so it’s know as multicellular organisms.
- The multicellular organisms have complex body organization.
- The multicellular organisms organisms life span is long
- They have only include eukaryotes.
- These organisms are reproduced by sexual reproduction.
- The multicellular organisms cells differentiation is obvious.
- The multicellular organisms are visible to the naked eyes.
- The multicellular organisms outer cell are exposed to the environment.
- In multicellular organisms injury doesn’t cause to the death.
- The multicellular organisms operational efficiency is high.
- The multicellular organisms are evolved from the prokaryotes.
- The multicellular organisms are larger than unicellular organisms size.
- The multicellular organisms shape is well defined.
- Animals, plants, human beings, birds & insects all are the examples of multicellular organisms.
