Why can water pass through the semipermeable membrane, but not salt or sugar? There’s no answers it’s just space to write but I don’t know what to write can someone please help?

due to large size of salt and sugar

Explanation:

Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose and other sugars) cannot. First, imagine a semipermeable membrane, one that will allow water to pass through but keeps in dissolved molecules
