Profitability control is a mechanism of monitoring the sales made, profits earned and expenditure incurred by a company. The relative profit earning capacity of a firm’s products and consumer groups can be determined via profitability control. Sometimes surpisingly, it may be found out by companies how a small proportion of their products and even customers actually account for a significant percentage of the company’s profits. This can be achieved through profitability control. At times when the companies earn surplus profits, then such profits may even be ploughed back or reinvested.

While plant cells have chloroplasts to photosynthesize, they also require ATP for cellular functions, and do use oxygen to break down some of the sugar they produce in order to generate that ATP. They need mitochondria for this.

In particular, at night when there is no light, plants undergo cellular respiration since there is no sunlight to photosynthesize.

They do, however, produce far more sugar and oxygen through photosynthesis than they use up in respiration.
