Sketch what you observe when examining the onion root tip using the low-power lens and the high-power lens. label the sketches or write a brief description of your observations.

The "power" of a lens refers to its resolving power, which is the ability to differentiate between two closely spaced points. Because the power of the second lens is higher, you will be able to view more details and make a more detailed sketch. This new sketch will more accurately show structures such as root hairs and other parts of the root tip which were initially indistinguishable from one another when the low power lens was being used.

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.
