Just as density is most often used to mean mass density, the term linear density likewise often refers to linear mass density. However, this is only one example of a linear density, as any quantity can be measured in terms of its value along one dimension. Consider a long, thin rod of mass and length .
Animal cells do not undergo photosynthesis, but in a plant cell, the site of photosynthesis is the chloroplast. Prokaryotes are more primitive-they have no nucleus for a start, and also have no chloroplasts.They are bacterial cells and so do not undergo photosynthesis.ating Newest Oldest. Best Answer: Actually, some procaryotes have photosynthesis. The thing is, as they don't have organelles, it doesn't occur in a differentiated structure, like choroplasts in eucaryotes. It happens along the plasma membrane.
Prokaryotes get energy by performing chemical reactions within the cell. All organisms are able to do glycolysis, which splits a molecule of glucose in half and releases a little bit of energy in the form of ATP(adenosine triphosphate). Some prokaryotes are also capable of additional reactions that produce more energy, similar to what happens in the mitochondria of eukaryotes. Aerobic prokaryotes contain the enzymes necessary to break down the pyruvate to carbon dioxide and produce a little more ATP, along with some electron carrier molecules like NADH and FADH2.
