The nucleus, chloroplast, and mitochondria have in common is that they are membrane-bound organelles in a cell.
Hi! Both organelles have DNA (mitochondria and chloroplast), so that is a similarity. One difference is that chloroplasts are usually found in plants. The main role of chloroplasts is to produce energy (in the form of ATP and NADH) using the light energy of the sun.i! Both organelles have DNA (mitochondria and chloroplast), so that is a similarity.
