Cells are the basic units of life and there are two main types, prokaryotes and eukaryotes. Prokaryotes are cells that do not have a nucleus or membrane bound organelles, whereas eukaryotes do. Answer and Explanation:1 Prokaryotes, including archaea, do not have a mitochondria. A mitochondria is...
Prokaryotic literally means 'before the nut or kernel', referring to the nucleus of the cell. The genetic material is circular; it is neither organised nor contained within a specialised membrane. Bacteria are prokaryotes and range in size from 0.2 – 2.0 µm. What does prokaryotic mean in ...
What does the nucleus do in a cell? What are the different organelles that make up our cells? What are their functions? What are the functions of the cytoskeleton? How do prokaryotes function without organelles? What is the function of the endoplasmic reticulum?
Prokaryotesare organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure....
Escherichia coli and all other prokaryotes have developed elaborate mechanisms to adapt their metabolism to a rapidly changing environment. Some of these mechanisms allow the bacteria to approach or to flee particular chemicals (Adler, 1975; Boyd and Simon, 1982). We will not discuss such mechanisms...
a Prokaryotes are single-cell organisms, such as bacteria, that have no real nucleus and do not contain membrane-enclosed organelles. Eukaryotes, such as algae, fungi and protozoa, have a real nucleus and membrane-enclosed organelles. Viruses are tiny, complex molecules composed of protein and ...
thylakoid membraneDuring their evolution from cyanobacteria, plastids have relinquished most of their genes to the host cell nucleus, but have retained a core set of genes that are transcribed and translated within the organelle. Previous explanations have included incompatible codon or base composition,...
Unlike plant and animal cells, prokaryotic cells contain no membrane bound organelles or an organized nucleus. Based on this theory, organelles such as the mitochondria in modern eukaryotic cells would be the evolutionary descendents of the aerobic prokaryotic cells engulfed by the larger prokaryotes....
