Difference between Unicellular organisms & Multicellular organisms (zooconcept)

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.

Contents:-

  • What are the unicellular organisms?
  • The general character of the unicellular organisms.
  • What are 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.
