The evolution of single-celled organisms is estimated to have occurred around 3.5 billion years ago, while the evolution of multicellular organisms is believed to have started around 600 million years ago. This means there was a gap of about 2.9 billion years between the evolution of single-celled and multicellular organisms.
Sexual reproduction evolved before the evolution of multicellularity. Organisms were able to reproduce sexually as single-celled organisms before multicellular life forms emerged.
The main difference between unicellular organisms and multicellular organisms is that unicellular organisms are made up of a single cell, while multicellular organisms are made up of multiple cells that are specialized to perform different functions. Multicellular organisms have a higher level of complexity and organization compared to unicellular organisms.

Three differences between unicellular and multicellular organisms is that unicellular organisms are microscopic and can live in extreme temperatures. Multicellular organisms are much larger and have systems and organs.
The antonym for unicellular is multicellular. Organisms that are multicellular are made up of multiple cells, while unicellular organisms are made up of a single cell.

multicellular organisms begin as a single cell.

Usually Bacteria is unicellular, but in some cases multicellular.

Eukaryotic cells can be found in both multicellular and single celled organisms. A eukaryotic is an organism that has a nucleus.

The antonym for unicellular is multicellular. Organisms that are multicellular are made up of multiple cells, while unicellular organisms are made up of a single cell.
Usually Bacteria is unicellular, but in some cases multicellular.
Bacteria tend to be single celled organisms.
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.
