Why is the term prokaryote misleading?
Pace contends that the term prokaryote refers to the lack of a nucleus and that it is hence a “negative and therefore scientifically invalid description” of cell organization, because “no one can define what is a prokaryote”.
Why is it important to understand the differences between prokaryotes and eukaryotes?
It is important to know the differences between prokaryotic and eukaryotic cells; allows us to control disease-causing bacteria without harming our own cells.
What are the two main reasons that make prokaryotic and eukaryotic cells different from each other?
There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell’s genetic material, while prokaryotic cells don’t have a nucleus and have free-floating genetic material instead.
Why is it difficult to culture prokaryotes?
Some bacteria cannot be cultured because they are obligate intracellular parasites and cannot be grown outside a host cell. In other cases, culturable organisms become unculturable under stressful conditions, even though the same organism could be cultured previously.
What is prokaryotic and eukaryotic definition?
Prokaryotic cells are cells without a nucleus. Eukaryotic cells are cells that contain a nucleus. Eukaryotic cells have other organelles besides the nucleus. The only organelles in a prokaryotic cell are ribosomes.
Why are fungi eukaryotic?
Fungi are eukaryotes and have a complex cellular organization. As eukaryotes, fungal cells contain a membrane-bound nucleus where the DNA is wrapped around histone proteins. Unlike plant cells, fungal cells do not have chloroplasts or chlorophyll.
What effect do you expect the structural differences between prokaryotes and eukaryotes to have on their functions?
What effect do you expect the structural differences between prokaryotes and eukaryotes to have on their functions? Eukaryotes are more complex so they are capable of doing more things. If a cell is missing a nucleus, what will so be missing?
What makes prokaryotes different from eukaryotes?
Comparing prokaryotes and eukaryotes The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not.
What do the prokaryotes and eukaryotes have in common?
Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The cytoplasm is all the contents of the cell inside the cell membrane, not including the nucleus.
What do prokaryotic cells have that eukaryotic don t?
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. Prokaryotes, on the other hand, have no membrane-bound organelles.
Why is it so difficult to arrive at a simple species definition for prokaryotes?
why is it so difficult to arrive at a simple species definition for prokaryotes? bacteria isolated and grew slowly and was more resistant to antibiotics. which G- phylum contains the most metabolic diversity of any phylum and the largest # of described species?
Do prokaryotes cause disease in humans?
Harmful Prokaryotes Such harmful bacteria is called pathogenic bacteria, bacteria that are able to invade the body, cause an infection, or damage the body in some way.
