Question

why do we need to label the membrane? click the view theory button in case you doubt which one is the correct answer. a) to check whether the synthetic cells have a membrane b) to visualize the transport proteins using the fluorescent microscope c) to visualize the cell membrane using the fluorescent microscope d) to visualize the cargo molecules using the fluorescent microscope

Explanation:

Labeling the membrane with fluorescent markers allows it to be seen under a fluorescent microscope. It's not about checking if synthetic cells have a membrane (usually known beforehand), nor about visualizing transport or cargo molecules specifically in this context of membrane - labeling.

Answer:

c) To visualize the cell membrane using the fluorescent microscope
