what does it mean if a membrane is semi-permeable or selectively permeable (these mean the same thing).

• All substances can pass through the membrane.

• No substances can pass through the membrane.

• Some substances can pass through the membrane.

In the image shown, Sugar cannot pass through the membrane. Why is the sugar unable to pass through the membrane.

• Not enough information is given

• It's too large to pass through the membrane.

• Chemical properties prevent it from passing through the membrane.
