Flowering Plants: Early Growth and Development - 1 Following the double fertilization in the flowering plants, the zygote develops into the embryo, the endosperm nucleus into the endosperm tissue, the embryo sac wall and integuments of the ovule into the seed coat and the ovary and accessory tissue into the fruit. In this section we will discuss the development of the embryo, seed and fruit maturation, dispersal and germination. Embryo Development The first division of the zygote produces a small proembryo cell and a larger basal cell that develops the stalked suspensor, which elevates the developing proembryo into the endosperm tissue. Zygote (within the embryo sac) | First Division | | | Upper cell Lower cell Proembryo Basal cell of the Suspensor | | Mass of cells Suspensor Stalk (surrounded by endosperm) Suspends embryo into endosperm | Proembryo, divided into 3 layers Protoderm ---> Surface Tissues Procambium ---> Vascular Tissues Ground Meristem ---> Ground Tissues | The embryo takes on the shape of an axis with meristems at both ends.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
