It would be more accurate to say that each pgr controls specific cellular processes because they do not controldevelopment of specific organs (which actually is unknown how organ formation is controlled) they simply influence it. Also, by influencing development they must control specific cellular processes to cause differentiation and development.
A nucleus in a plant and animal cell controls all of the activities in a cell.
In short, an embryo undergoes both cellular division and cellular differentiation to become a fetus. This is achieved by the genetic program present in the cell(s) which controls both mentioned processes. It is the stage of developing mammal.After 9th week of fertilisation,the embryo can be called foetus.
DNA controls no processes, organs or organs systems in the body. Deoxyribo Nucleic Acid works are the celluler level.
Nucleus is the commanding center . It controls cellular activities.
The cerebrum controls the higher processes and senses of the body.
Nucleus
Nucleus controls most of the cell process. It also contains the hereditary information called DNA.
The endocrine system controls many body processes. Among these are growth and development, metabolism, reproduction and body defense.
