Unicellular protoctists are eukaryotic organisms that can be photosynthetic, heterotrophic, or mixotrophic in nature, while bacteria are prokaryotic organisms. Protoctists have a nucleus and other organelles enclosed in a membrane, whereas bacteria lack a defined nucleus and organelles. Additionally, bacteria have a cell wall composed of peptidoglycan, while protoctists may have cell walls made of various materials or lack them altogether.
A microorganism is a tiny organism that can be single-celled or multi-celled, while a unicellular organism is an organism that is composed of only one cell. Therefore, all unicellular organisms are microorganisms, but not all microorganisms are unicellular.
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.
There is no difference between the sugar-phosphate arrangement in the backbone of the DNA from the plant, mammal, and bacterium. What makes plant, mammal, and bacterium different is the sequence of the DNA nucleotides.
A unicellular organism is made up of a single cell that performs all necessary functions, while a multicellular organism is made up of multiple cells that are specialized to perform specific functions. Multicellular organisms are typically larger in size and have a higher level of complexity than unicellular 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.
the difference between bacteria and protoctist is that the protoctist have a necleus while the bacteria don't.... in other words the bacteria is a prokaryotes and the protoctist is a eukaryotes
bacterium are prokaryaotic (no nucleus) while unicelluar (possessing a single cell) are eukaryotes. Although they have a nucleus, they are essentially comprised of only a single cell.
What is the difference between a unicellular and multi?
There is not a difference between bacteriod and bacterium. Both are bacteria.
Bacteria are unicellular organisms, which is to say, a bacterium is a cell. Bacteria differ from the cells of multicellular organisms in that they are generally much smaller and less specialized.
bacteria is plural and bacterium is singular
The best way to distinguish between a single-celled protoctist and a prokaryote is to look at their cell structure. Protoctists, also known as protists, have a membrane-bound nucleus and other organelles, making them eukaryotic. Prokaryotes, on the other hand, lack a membrane-bound nucleus and other organelles, and their genetic material is contained in a single, circular chromosome.
The ONLY difference is that Protozoans are unicellular and animals multicellular
a bacteria is smaller than an animal
Unicellular is made up of one cell and multi-cellular is made up of many cells.
Animal-like protists are unicellular~
A pathogenic bacterium is alive while a virus is not.
