Function of nucleus, mitochondria ,endoplasmic reticulum, vacuoles

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.

A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.

Hope this helps!!
