Cell-surface receptors are involved in most of the signaling in multicellular organisms. There are three general categories of cell-surface receptors: ion channel-linked receptors, G-protein-linked receptors, and enzyme-linked receptors.
Even though both organelles are found in eukaryotic cells<span>, both </span>mitochondria and chloroplast<span> have characteristics often found in </span>prokaryotic cells<span>. These </span>prokaryotic cell<span> characteristics include: an enclosed double membrane, circular DNA, and bacteria-</span>like<span> ribosomes.</span>
They are all used to measure volume
both having gravity, you can touch and see both of it. It also possible if microorganisms can live on both of them.
They both have shape also.
