      2. (botany) The top cell of the suspensor in a dicot embryo, which will differentiate to form part of the root cap.
        • 1995 - Trevor A. Thorpe, In Vitro Embryogenesis in Plants, Springer, ISBN 0792331494, page 85
          All the cells of the suspensor, except one, are eventually crushed and obliterated by the growing embryo; this fortunate cell known as the hypophysis is the one in immediate contact with the embryo and plays an important role in the formation of the root apex.
