mitochondria
A system carries out more activities than an organ. An organ is a part of a system and it performs specific functions, while a system is made up of multiple organs working together to perform complex, coordinated functions necessary for the survival of an organism.
polyphasic activities
The things that perform necessary activities for the cell are called organelles. Each organelle has their own job to accomplish for the cell.
CHROMOSOMES! DNA consisting of nucleotides present in the chromosomes carries coded instructions for the cell's activities.
autonomic nervous system.
You will have to rephrase this. Your question is garbled.
The DNA is the hereditary material that carries the "code" to a cell's activities and structure.
metabolic activities
The structure that carries coded instructions for the cell's activities is the DNA molecule. DNA contains genetic information that codes for proteins and regulates cell processes. This information is transcribed into RNA, which then directs cellular functions.
