Entomology: The Study of Insects and their Relatives Insects and their terrestrial relatives belong to the phylum called Arthropoda and have inhabited the earth for an extensive time. Paleontologists show that the earliest fossils‚ most primitive forms of arthropods date back to the Devonian Period over 350 million years ago (Henning 1981). By the Age of Dinosaurs‚ 300 million years ago‚ insects were abundant in number and diversity. Like the dinosaurs‚ some pre-historic forms of insects were

PRACTICAL 6 Seed Plants (Gymnosperms and Angiosperms) OBJECTIVES: 1. To describe the features of seed plant life cycle and the concept of the dominant generation. 2. To describe the life histories and related reproductive structures of gymnosperms and angiosperms. 3. To summarize the features that distinguish gymnosperms and angiosperms. 4. To discuss the advantages of seed plants to dominate land and their evolutionary adaptations on land. EXPERIMENT 1: Gymnosperms INTRODUCTION: Gymnosperms

Since commercial beekeepers have came into the picture the queens are only allowed to mate with male drones that are producing offspring that are better pollinators. This process as produced a sort of inbreeding‚ where the queen does not have

carry the pollen to seeds. Since the neighbor sprayed insecticide because the Japanese beetles attacked their rose garden‚ there are no insects there to carry the pollen. Fruits won’t form unless the flowers are pollinated. Insects are considered pollinators for plants‚ without them the pollen would not go around. Pollination is needed to produce new seeds and create a wide variety of plants. 4. Table 16.7 Uses of Seeds Plants: Angiosperms and Gymnosperms Uses of Plants Example Angiosperm/Gymnosperm

Individual members of the corolla are called petals‚ which are often conspicuously colored to attract insects or birds that serve as pollinators. Plants that are wind-pollinated or that self-pollinated do not have colorful petals‚ such as the model plant Arabidopsis. Fig. 1.
