What is neither a eukaryotic or prokaryotic cell?
Viruses are considered neither prokaryotes nor eukaryotes because they lack the characteristics of living things, except the ability to replicate (which they accomplish only in living cells).
Which of the following is true of prokaryotes but not eukaryotes?
Eukaryotes contain a nucleus while prokaryotes do not. Eukaryotes are organisms whose cell contain a true nucleus and other membranous organelles such as endoplasmic reticulum, plasma membrane, cytoplasm, mitochondria, and rod shaped ribosomes that carryout out different functions in the cell.
What is not true about prokaryotic cells?
”Prokaryotic cells have a nucleus” is the statement about prokaryotic cells that is NOT true. Prokaryotic cells are cells that lack a true nucleus and some other cell organelles. The components of prokaryotic cells include plasma membrane, cell wall, cytoplasm, nucleoid, ribosomes, DNA (deoxyribonucleic acid).
Which of the following is a true difference between prokaryotic and eukaryotic cells?
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 only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.
What was the first prokaryotic cell?
The first prokaryotes were adapted to the extreme conditions of early earth. It has been proposed that archaea evolved from gram-positive bacteria as a response to antibiotic selection pressures. Microbial mats and stromatolites represent some of the earliest prokaryotic formations that have been found.
Are all bacteria are prokaryotes?
Only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes—pro means before and kary means nucleus. Animals, plants, fungi, and protists are all eukaryotes—eu means true—and are made up of eukaryotic cells.
