1 The electron micrograph shows onion root cells prepared using a freeze-fracture technique. The cells were quickly frozen and then physically broken apart. Freeze fracture breaks apart cells along weak areas, such as membranes and the surfaces of organelles.
Which statement best explains the appearance of the electron micrograph?
1 )
The cells were broken apart at the endoplasmic reticulum; structure X is a ribosome.
The cells were broken apart at the nuclear envelope; structure X is a nuclear pore.
3 )
The cells were broken apart at the nuclear envelope; structure X is a ribosome.
4 )
The cells were broken apart at the tonoplast; structure X is a plasmodesma.
