All invertebrate means is lacking a spinal chord, so, there are many single-celled and many multi-celled invertebrates.
All animals that are made up of more than one cell are called multicellular organisms, therefore invertebrates, such as stick insects are multicellular.
multicellular
Vertebrates are multicellular.
Archaeabacteria are all unicellular organisms. (one, not multiple)
One way that single-celled organisms are different from multi-celled organisms is in their complexity. Single-celled organisms consist of just one cell, while multi-celled organisms are made up of multiple cells organized into specialized tissues, organs, and systems. This allows multi-celled organisms to perform more complex functions and have greater structural and functional diversity.
Usually Bacteria is unicellular, but in some cases multicellular.
yes bacteria is a single celled organisms.
Kingdom: Protista They are eukaryotic
They eat, they exrete, they respire, they reproduce and they die.
Archaeabacteria are all unicellular organisms. (one, not multiple)
There are no single-celled organisms large enough for you to actually see with your naked eye. All animals you can see are multiple cells.

Only complex, multi-celled animals can be classified as vertebrate or invertebrate. Bacteria, being single-celled organisms are neither vertebrate nor invertebrate.
what is the group of mainly single celled organisms called
No. Tissues are aggregations of multiple cells, which do not occur in single-celled organisms.
Amoebas are single celled organisms. They do not have any particular shape. Another group of single-celled organisms like amoebas are protists.
Bacteria are single-celled organisms.
