The structure of the flower
The purpose of this lesson: Flower knowledge construction, understanding dust
Parts of the flower
- There are two main types of pollination: self - pollination (when the plant is pollinated with its own pollen) and cross-pollination. If cross - pollination plants can produce two basic types of plants: monoecious and dioecious. Biotic pollination (with the help of living organisms) Entomophily — pollination by insects; as a rule, bees, wasps and sometimes ants (Hymenoptera), beetles (Coleoptera), butterflies (Lepidoptera) and flies (Diptera). Zoophilia pollination by vertebrates: birds (ornithophily, agents of pollination are birds such as hummingbirds, sunbirds, medonosy), bats (chiropterophily), rodents, some marsupials (in Australia), lemurs (in Madagascar). Artificial pollination — the transfer of pollen from stamens to pistils of the flowers through the human.
Questions on for size: 1. What are the main sections of the flower? 2. What is pollination ? 3. How many types of pollination of flowers you know? 4. Give an example
