Characteristics of Unicellular Organisms
Apart from these, examples include diatoms, Euglena, chlorella, and Chlamydomonas. In order to get an idea of how these organisms look like, you can study microorganisms in pond water. For biological experiments, collect fresh water samples from garden ponds in small bottles. Using eye drops, put a drop of water sample on a slide, gently place the slip cover on it, and observe under a microscope. You will find randomly moving minute organisms, most of which are organisms that have a single cell. Organisms, which consist of many cells and are much larger and more complex compared to unicellular organisms.
Single-celled or single-celled organisms or unicellular organisms are special organisms. The number of unicellular organisms is not as much as multicellular organisms that almost cover all living things. Unicellular organisms have certain characteristics. Some of the characteristics of these unicellular organisms are having invisible or microscopic body shapes or which can only be seen using a microscope, but sometimes there are also unicellular organisms that can be seen using the naked eye.
Unicellular organism part
Since it was mentioned earlier that these unicellular organisms are microscopic creatures, most of which are unicellular organisms are a type of bacteria or protozoa or germs and their friends. Some examples of unicellular organisms are:
Multicellular organisms
has undergone cell differentiation, which performs special functions.
For example: nerve cells, blood cells, muscle cells, all perform different functions.
Most of life, which can be seen with the naked eye, is a multicellular organism.

Multicellular Organisms
Organisms, which are composed of many cells and are much larger and more complex compared to unicellular organisms. Multicellular organisms have undergone cell differentiation, which performs special functions. For example: nerve cells, blood cells, muscle cells, all perform different functions Most of life, which can be seen with the naked eye, is a multicellular organism.
A multi-cell organism - covering all organisms from the Plantae and Animalia kingdoms - fish, humans, tigers, horses, cows, dogs, sheep, snakes, whales, elephants, mango trees, roses, plants, plants, etc.
Examples of multicellular organisms
A multi-cell organism - covering all organisms from the Plantae and Animalia kingdoms - fish, humans, tigers, horses, cows, dogs, sheep, snakes, whales, elephants, mango trees, roses, plants, herbs, etc. Humans are the best examples from multicellular organisms. Multicellular organisms are also known as 'eukaryotes' or 'eukaryotic entities'.
Characteristics of Multicellular Organisms
Having more than one cell (many)
Organisms have a large size
The composition and structure of the body is very complex and complicated
Having various organs that perform different functions
Has a separate cell and DNA nucleus
Although in general multicellular organisms are larger, there are also microscopic sizes known as myxozoa. Some examples of multicellular organisms are humans, animals, plants, myxozoa, and all types of fungi.

Classification of Organisms
Organisms are grouped into five kingdoms based on:
The presence or absence of a core membrane
Unicellular (single cell) or multicellular (multiple cells)
Types of nutrients used by organisms (heterotrophic or autotrophic)
Kingdom Monera
* Has a primitive cell structure lacking a nuclear membrane - prokaryotes
* Most of these kingdoms are unicellular (some are in multicellular clusters)
* Two main phyla, namely: Bacteria (heterotrophic) and Blue-green Algae (autotrophic)
Kingdom Protista
* Has a membrane around the cell nucleus - eukaryotic
* Dominated by unicellular organisms
* Two main phyla namely: Protozoa - heterotrophic animals (paramecia, amoeba), Algae - autotrophic plants (Spirogyra)
Kingdom Fungi
* Has a membrane around the cell nucleus - eukaryotic
* Absorb food from the environment (heterotrophic)
* Arranged in many nucleated filaments such as bread mold (multicellular), mushroom (multicellular), yeast (unicellular)
