In eukaryotic cell architecture, what is the rigid outer layer of a plant cell that provides structural support and protection?
A
Nuclear envelope
B
Glycocalyx
C
Cell wall
D
Plasma membrane
Verified step by step guidance1
Identify the key components of eukaryotic cells, focusing on plant cells specifically.
Recall that plant cells have a unique rigid outer layer that is not present in animal cells.
Understand that the nuclear envelope surrounds the nucleus, the glycocalyx is a carbohydrate-rich layer found in some animal cells, and the plasma membrane is a flexible boundary of the cell.
Recognize that the rigid outer layer providing structural support and protection in plant cells is called the cell wall.
Conclude that among the options given, the cell wall is the correct answer as it is the characteristic rigid outer layer of plant cells.
