Now what's interesting here is that lens fibers as their first forming, they start out as cells with organelles.But as the eye develops, the cells lose all of them, including the nuclei.And without organelles, the lens fiber is nice and clear.And all those lens fibers packed together ...
Why is telomerase not active in somatic cells? Why do some cells have more mitochondria? Why do cells spend most of their life in interphase? Why do epithelial cells have many mitochondria? Why aren't chloroplasts in animal cells? Why do cells have organelles?

as these oblong organelles are where aerobic respiration takes place. Aerobic respiration generates 36 to 38 molecules of ATP, or adenosine triphosphate (the cells' main energy source) for every molecule of glucose (the body's ultimate fuel currency) it consumes; glycolysis, on the other hand, ...
How can prokaryotic cells be smaller than eukaryotic cells and still carry on all the functions of life? How do prokaryotes function without organelles? How do autotrophs differ from heterotrophs in obtaining energy? Why do cells in your body differ from each other?
Despite the significant advances made in the field of bacterial cell biology in the past 15 years, little is known about the mechanisms employed by to shape, position and segregate organelles, or how the cells can discriminate and address specific proteins to these compartments. Then, if did ...
•Ribosomes:Found in the cytoplasm of all organisms and elsewhere in eukaryotes, these are the protein "factories" of cells, and consist of two subunits. They contain the sites upon wheretranslationoccurs. Eukaryoteshave more complex cells, containing _organelles, which are surrounded by the same...
(B) Schematic overview of the molecular cross-talk between archaea and human immune cells. Archaea are rapidly phagocytosed by human dendritic cells and subsequently degraded within the phagolysosome. Recognition of archaea via PRRs occurs after internal degradation and leads to the release of (pro...
