Which organelles would be present in large numbers in cells that require manufacture proteins?

Cells that require the manufacture of proteins would have a high number of ribosomes and endoplasmic reticulum. Ribosomes are responsible for protein synthesis, while the endoplasmic reticulum is involved in protein folding and processing. Additionally, Golgi apparatus and mitochondria may also be present to help with further protein processing and energy production for cellular activities involving protein synthesis.
