Learning ObjectivesYou should be able to:
(a) define asexual reproduction as the process resulting in the production of genetically identical offspring from one parent (b) define sexual reproduction as the process involving the fusion of nuclei to form a zygote and the production of genetically dissimilar offspring (c) identify and draw, using a hand lens if necessary, the sepals, petals, stamens and carpels of one, locally available, named, insect-pollinated, dicotyledonous flower, and examine the pollen grains under a microscope (d) state the functions of the sepals, petals, anthers and carpels (e) use a hand lens to identify and describe the stamens and stigmas of one, locally available, named, wind-pollinated flower, and examine the pollen grains under a microscope (f) outline the process of pollination and distinguish between self-pollination and cross-pollination (g) compare, using fresh specimens, an insect-pollinated and a wind-pollinated flower (h) describe the growth of the pollen tube and its entry into the ovule followed by fertilisation. (production of endosperm and details of development are not required) |
