The nucleus, chloroplast, and mitochondria have in common is that they are membrane-bound organelles in a cell.
1. Chloroplast contains thylakoid membranes and pigment molecules, whereas the mitochondria membranes contain respiratory enzymes not found in chloroplast membranes. 2.Chloroplasts are found in plants only while mitochondria are found in both plants and animals.3. Chloroplasts help in photosynthesis.itochondria on the other hand are found in both animal and plant cells and are engaged in the production of ATP. To use simple layman language, mitochondria in animal cells changes energy into forms that animals can use, while chloroplasts in plant cells convert sunlight into energy that plants can use.
