Producers, like this plant, take in oxygen and release carbon dioxide during , just like animals and other living things

During the process of cellular respiration, the cells use oxygen and give up carbon dioxide as their by product.

Some plants also take in oxygen and release carbon dioxide during the process of cellular respiration. The cellular respiration in the plant is similar to the cellular respiration, which occur in animals.

Hence, the given blank can be filled with cellular respiration.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
