                1.        Reproduction in Plants

                Students should be able to:

                1.1.     describe  the  structure  of   Annotated   diagrams
                         the   anther   and   the   required.
                         formation of pollen grains;

                1.2.     describe  the  structure  of   Annotated   diagrams    Make  drawings  of  the
                         the ovule and the formation   required.                anther  and  embryo  sac
                         of the embryo sac;                                     from prepared slides.

                1.3.     explain  the  sequence  of   Annotated     diagrams
                         events  from  pollination  to   required.
                         fertilization;

                1.4.     explain   how      cross-   Non-synchronous
                         fertilization is promoted;   maturation  of  stamens
                                                    (protogyny)  and  carpels
                                                    (protandry),    separate
                                                    sexes   (dioecy),   insect
                                                    pollination,        self-
                                                    incompatibility     and
                                                    sterility.

                1.5.     discuss   the    genetic   Self-fertilization and cross
                         consequences  of  sexual   fertilization.
                         reproduction;

                1.6.     explain  the  significance  of
                         double  fertilization  in  the
                         embryo sac;
