2. The grainy substances surrounding the onion cell nucleus are a) the cell wall, b) cytoplasm, c) the cell membrane, or d) chloroplasts

3. One structure in green leaf cells that you don't see in onion cells is a) a nucleus, b) a cell wall, c) chloroplasts, or d) cytoplasm

I am not from Science stream, But I guess, In onion structure one is cell wall and chloroplasts. The grainy substances surrounding the onion cell nucleus are one is cell membrane and cytoplasm. One structure in green leaf cells in onion cells is that is cell wall and chloroplasts.
