Which of the statements about plant cell walls is true? Select all that apply.

The primary cell wall is thin and flexible, formed while the cells are still growing.

In the late stages of cell division, the middle lamella is the first cell wall layer to be formed, serving to attach the daughter cells to each other.

The secondary cell wall contains complex components such as lignin that are rigid.

The cell wall has three layers: the middle lamella, the primary cell wall, and the secondary cell wall.

Like the extracellular matrix formed by animal cells, the cell wall polymers are formed in the cytoplasm and secreted to the outside of the cell.
