Ans: All the above options are correct.
Cellular Respiration: It is nothing but a process of making energy. It is a process in which ADP is converted into ATP and it happens in the mitochondria present in the cell. The cell uses oxygen and glucose to make ATP or cellular energy releasing water and carbon dioxide as well.
Protein Synthesis: This process occurs both in plants and animals. The proteins are synthesized by every individual cells necessary for cell structure and function. In plants it primary occurs in three main compartments: mitochondria, platsids and cytoplasm. The process of protein synthesis involves two main process viz: transcription of DNA to produce premature mRNA which gets processed into matured mRNA after which it gets translated into proteins. Both the process involves several enzymes and factors taking part.
DNA replication: A process in which a single DNA molecule is copied that results in the formation of two identical molecules before cell division occurs. It involves lots of enzymes and physical factors. This process plays an important aspect to the continuity of plants and other forms of life. The order in which the information of sequences are arranged in the DNA determine which part of the plant will be formed.
Photosynthesis: A process unique to autotrophs that make their own nutrients and does not depend on others. This process helps plants to convert light energy into chemical energy. It is a primary source of energy in plants and is an endothermic chemical process. In plants it occurs in green leaves and stems that has a chloroplasts present in it. Carbon dioxide and water is absorbed by plants which by a photosynthesis gets converted into glucose and oxygen.
