Plants are grown in glasshouses to protect them from the weather or extend the growing season. Plants make food by photosynthesis.

In winter, when days are shorter, glasshouses are heated to keep the enzyme reactions in plants at optimum rates.
What else should a grower do to make sure that the plants are photosynthesising at the optimum rate? Give a reason for your answer.

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.

Iwould say overuse ( but not 100% sure ) in the u.s. we tend to overuse water by leaving it running, throwing it away, taking long showers, etc.
