Question
What are some examples of the different types of membranes? Explain why they are different.
Answer
Examples of different types of membranes include cell membranes, nuclear membranes, and endoplasmic reticulum membranes. Cell membranes are selectively permeable, allowing certain molecules to pass through while blocking others. Nuclear membranes are double-layered and contain nuclear pores that allow for the exchange of molecules between the nucleus and the cytoplasm. Endoplasmic reticulum membranes are composed of a lipid bilayer and are involved in the synthesis and transport of proteins. They are different because they have different structures and functions.
