Final answer:
The cell body or soma of a neuron contains the organelles responsible for its basic metabolic processes, including the nucleus and mitochondria.
Step-by-step explanation:
The part of a neuron that contains the organelles responsible for basic metabolic processes of the cell is known as the cell body or soma.
This area houses the nucleus, which is the control center for the cell, as well as important organelles such as smooth and rough endoplasmic reticulum, Golgi apparatus, mitochondria, and others. The soma is essential for maintaining the neuron's health, as it is the site for crucial cellular processes.
