What are prokaryotic and eukaryotic cells? Do prokaryotes have exons? What organelles are found in prokaryotes? Is a cheek cell a eukaryote or prokaryote? The eukaryotic cell organelle that most resembles a bacterial cell is the: A. nucleus B. Golgi apparatus C. mitochondria D. lysosome E. ri...
Which of the following does a prokaryotic cell have that an animal cell does not? a. Ribosomes. b. Cell wall. c. Vacuole. d. DNA. Cell Organelles: A cell is a structure that is found in both plants and animals. A cell can be...
Prokaryote, also spelled procaryote,any organism that lacks a distinct nucleus and other organelles due to the absence of internal membranes. Bacteria are among the best-known prokaryotic organisms. The lack of internal membranes in prokaryotes distinguishes them from eukaryotes. ... Some prokaryotes ...
Through what process can viruses enter into eukaryotic cells which cannot be used on prokaryotic cells? Explain the process. What is the role of the cytoskeleton in cell division (mitotic spindles, centromeres, kinetochores, contractile rings,...
Mature cells of all terrestrial plants, most fungi, and algae (except prokaryotic cells) have vacuoles. However, there are no vacuoles in animal cells and in the immature plant cells, as well as some highly mature plant cells (such as stone cells). What is the benefit of having contractile...
Although it is tempting to speculate that the appearance of membrane-bound organelles was an adaptation that made it possible for primitive prokaryotic viruses to colonize eukaryotic hosts, further evidence from +RNA viruses of the archaea and eubacteria is needed to address this question. Organelle-...
are far more complex than their prokaryotic counterparts. In addition to the four essential cell components listed above, these cells have a nucleus and a number of other membrane-bound structures called organelles. One of these organelles, the endoplasmic reticulum, has an intimate relationship with...
These different structures found within cells are called organelles.The endoplasmic reticulum is an organelle that can be found in botheukaryoticandprokaryoticcells.Just keep in mind that not all cells have endoplasmic reticulum! For example, red blood cells don’t have endoplasmic reticuli, even thou...
Whereas the Sec translocation pathway is found in the endoplasmic reticulum of eukaryotic cells and in the plasma membrane of prokaryotic cells, the recently discovered YidC/OXA1 membrane insertase is present only in prokaryotic and organellar membranes [19], [20]. Since KcsA, Bacteriorhodopsin, ...
plants make glucose, a type of sugar, and release oxygen, a waste product from the photosynthesis process. This chemical reaction takes place in the chloroplasts contained in the inner layers of plant leaves. Some plants have very small leaves and photosynthesis takes place in the bark or stems...
