What are the 11 functions of a cell?

Cells must perform 11 main functions in order to support and maintain life: absorption, digestion, respiration, biosynthesis, excretion, egestion, secretion, movement, irritably, homeostasis, and reproduction.

What is the main function of the cell body?

The main cell body function is to store the organelles of the cell and regulate production of proteins and lipids needed by the rest of the neuron. The cell body contains the nucleus and thus regulates gene expression. The proteins synthesized in the cell body can be transported to other parts of the neuron.
