Both are induced by molecules produced by female gametes. Pollen tube growth in plant pollen, acrosomal reaction in animal sperm. Pollen contains a tube nucleus and a generative cell that will divide to form two sperm cells. The sperm cells travel through the pollen tube to the embryo sac of the ovule. Acrosomal reaction occurs after sperm interacts with egg VE glycoproteins.
Acrosomal vesicle is released and digestive enzymes degrade egg surface molecules.
Bindin protein is then exposed to interact directly with egg surface glycoproteins in order to intitate fusion. Please define the following terms. Each is worth 5 points. Differentiation Specialization of cells. This creates cell type diversity in the developing embryo and results in cell types with specific functions.
