Students have asked these similar questions
Some scientists claim that prokaryotes like bacteria have membrane bound organelles, like chromatophores, anammoxosomes and magnetosomes. What really is the truth because it is widely known that prokaryotes do not have membrane bound organelles. Are these claims true or merely speculative? If this is true, what is the physiological basis for this?
Imagine that you are given an unknown cell sample. You visualize the sample under
the microscope and you notice that it has a large number of mitochondria. Based on
this observation, what can you say about the function of this cell?
The cell might be storing a large amount of toxins.
The cell might engulf and digest a large amount of material.
The cell might require large amounts of energy.
The cell might degrade large amounts of fatty acids.
"Without the cytoskeleton, the cell will not be able to perform any of its functions."
Is there truth behind this claim? explain
