Most important test question
Solution:
The correct option is Cell membrane.
Plant cells have a cell wall as their outermost barrier while animal cells have cell membrane as their outermost boundary. Cell wall is dead while cell membrane is living in nature.
The middle lamella is a pectin layer of cell wall present between the cell walls of two adjacent cells. It provides stability to the plant and helps in forming plasmodesmata between them. Nuclear membrane is present around nucleus.
