Which organelles can be found in both plant and animal cells? A)cell membrane, nucleus, and chloroplasts B)cell wall, cell membrane, and nucleus C)endoplasmic reticulum, cell membrane, and nucleus D) chloroplasts, cell wall, and endoplasmic reticulum

Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal element.

not too sure maybe olecranon process
