Secondary Wall Formation in Plant Cells Explained

Practice question

Question

Which statement correctly describes the formation of the secondary wall in a plant cell?

Options

Choose one · Correct answer highlighted

It is formed on the inner side of the primary wall as the cell matures. Correct It is formed outside the middle lamella in a young, actively growing cell. It replaces the plasma membrane when the cell stops growing. It is formed only between two neighbouring plant cells.
