    Do plants stop making use of nutrients in seed leaves once it develop its first leaves and leave them to die?

    Thanks in advance.

    Depends on the specific plant. Often in dicots like mammoth sunflower sprouts the two cotyledons (seed leaves) are used up and soon fall off, as the stem outgrows their width. I bet there exists a plant who keeps its seed leaves though.
