Is(are) present in both plant and animal cells. cellular respiration cell walls cell membranes cellular breathing

I think the correct answer would be the third option. Cell membranes are present in both plant and animal cells. Both cells are eukaryotic cells so that they both contain membrane-bound organelles like the mitochondria, nucleus, lysosomes and the endoplasmic reticulum. Also, Both cells have the same processes for reproduction including mitosis and meiosis. For plant cells, additional structures can be found namely the chloroplasts, vacuoles and the cell wall. Another difference of the two would be the size. Animal cells are smaller than plant cells. Animal cells would have sizes ranging from 10 to 30 micrometers while the plant cells would be 10 to 100 micrometers.
