What is the role of lateral meristems such as vascular cambium and cork-cambium in dicotyledonous plants and gymnosperms?

They are responsible for the primary growth and increase in length of the plant.

They contribute to the plant's ability to absorb water and nutrients from the soil.

They cause the increase in girth of the organs in which they are active, known as secondary growth.

They primarily function to promote the flowering and fruit production in plants.
