what is the difference between the protozoa and bacteria?
383496
Protozoa are eukaryotic organisms while bacteria are prokaryotic organisms. Protozoa do not have cell walls while bacteria have cell walls. Bacteria have either heterotrophic mode of nutrition or autotrophic mode of nutrition while protozoa have only heterotrophic mode of nutrition.

Protozoa are unicellular eukaryotic microorganisms lacking a cell wall and belonging to the Kingdom Protista. Protozoa reproduce asexually by fission, schizogony, or budding. Some protozoa can also reproduce sexually. Relatively few protozoa cause disease.

Bacteria are unicellular microorganisms, meaning they are made up of one cell. The cell membrane of a bacteria is a very thin layer, about 8 nanometers in thickness, that covers the whole body of the bacteria. ... The cell membrane separates the inner fluids of the cell, called cytoplasm, from the surrounding environment.

Bacteria are single-celled, prokaryotic organisms. ... Like plants and animals, bacteria must be able to carry out basic functions of life within their cells. Some of the same organelles are found in plant cells, animal cells and bacteria cells, including ribosomes, cytoplasm and cell membranes.

Because bacteria are prokaryotic, they do not have a nucleus and no membrane-bound organelles. In contrast, plants and animals are made up of eukaryotic cells, which means they have a nucleus and membrane-bound organelles like mitochondria or golgi apparatus.

Terms in this set (21) What is the difference between protists and prokaryotes? the major difference is that protists are eukaryotes while bacteria and archea are both prokaryotes. this means that prokaryotes do not have a nucleus, and contain circular DNA.

Bacteria are all single-celled. The cells are all prokaryotic . This means they do not have a nucleus or any other structures which are surrounded by membranes . Larger bacterial cells may be visible using a light microscope, however an electron microscope would be needed to see the details of the cell organelles.

Bacteria (singular is bacterium) are one celled living organisms with complete genetic 'codes' made up of DNA and RNA. A virus is a section of DNA or RNA enclosed by a protein shell. Bacteria are over 100 times larger than viruses, but both can still only be seen by using a microscope.

Kingdom fungi contain molds and yeasts. The key difference between fungi and protozoa is that the fungi are mainly multicellular eukaryotic organisms while protozoa are unicellular eukaryotic organisms.

How are bacterial cells different from the cells of eukaryotes? Bacteria are prokaryotes. Their genetic material is not contained within nuclei. Eukaryotes have their genetic material in the nuclei.

Protozoa--except for a few colonial forms--are unicellular, or single-celled, organisms; although, some argue that they are actually 'acellular'. Thus, the vast majority of protozoa are microscopic. However, they do exhibit an incredibly large range of sizes.

You can think of prokaryotes (bacteria) that have no nucleus or organelles like an empty house, whereas eukaryotes (protists) are like a house full of appliances that have different functions. Both are still houses, one is just more complex than the other. Additionally, protists are generally larger in size.

Summary. Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.

In contrast to prokaryotic cells, eukaryotic cells are highly organized. Bacteria and Archaea are prokaryotes, while all other living organisms are eukaryotes. Amoebae are eukaryotes whose bodies most often consist of a single cell.

Parasites are part of a large group of organisms called eukaryotes. Parasites are different from bacteria or viruses because their cells share many features with human cells including a defined nucleus. Parasites are usually larger than bacteria, although some environmentally resistant forms are nearly as small.

Bacteria are amongst the simplest of organisms – they are made of single cells. Their cell structure is simpler than the cells of animals, plants and fungi. Cells of bacteria are called prokaryotic cells . Cells of animals, plants and fungi are called eukaryotic cells .
