Explanation:
if you were trying to find the function of something it you would mainly think of roles, jobs, responsibilities, chores etc, where as if you were trying to find the structure it would be how something is made up or its form.
for example the srtucture of a plant, meaning its form or how it grew, its function depends on what type of plant, if it were just a regular plant or leaf, the stomata, cell wall, cell membrane, nucleus, chloroplasts, chlorophyll inside the chloroplasts, mitochondria, cytoplasm, would be requied to do their funtions i.e their jobs to keep the plant/leaf alive
The cell membrane functions as a selective barrier. We call these kind of membranes as differentially permeable or semi permeable membrane. It can decide what substances can pass in and out. Therefore it can surround the cytoplasm (which is the inside of a cell) to separate the cell's content from the surroundings.
