That is vegetative growth:

Vegetative growth means that the roots of plants grow from the radicle of seeds. When seeds germinate, meristem cells of radicle divide and grow, which makes roots grow continuously, and the fastest growth is the elongation area of roots.

Note: when the green plants grow nutritionally for a certain time, they begin to form flower buds, then bloom, bear fruit and form seeds. The growth of reproductive organs such as flowers, fruits and seeds of plants is called reproductive growth.
