Lesson 3
| Question | Answer |
|---|---|
| 1. During fertilization, the tip of the ___ enters the ovule. | Pollen tube |
| 2. The mature ovary, with its ___ is called a fruit. | Seeds |
| 3. After ___, the ovule develops into a seed. | Fertilization |
| 4. Female reproductive cells (ovules) are contained in the ___. | Ovary |
| 5. Movement of pollen from the anther of a plant to the pistil of a different plant is called ___. | Cross-Pollination |
| 6. This is the male reproductive cell of a plant. | Pollen |
| 7. Movement of pollen from the anther of a plant to the pistil of the same plant is called ___. | Self-Pollination |
| 8. This structure connects the stigma to the ovary. | ? (Style)(not on list) |
| 9. The stalk that holds up the flower. | Peduncle |
| 10. The colorful part of the flower is called the ______. | Petals |
| 11. This flower structure produces the pollen. | Anther |
| 12. When pollinated, this structure will host a ___ that will grow down to the eggs. | Pollen tube |
| 13. Another name for the seed eggs of a flower. | Ovules |
| 14. What flower parts are considered to be part of the female structure? | Stigma, style, ovary, ovule |
| 15. What flower parts are included in the male structure of the flower? | Filament, anther |
| 16. The job of the ____ is to protect the internal parts of the flower. | Sepals |
| 17. When all the sepals are put together as one unit we call it a ___. | Calyx |
| 18. Another name given for the pistil is ___. | Carpel |
| 19. The part of the flower that holds up the anther is called the ____. | Filament |
| 20. The slimy, sweet, aromatic liquid stuff secreted by the petals and stored and stored at the base of each flower is called ____. | Nectar (not on list) |
| 21. The term given to describe when all the petals are put together as one unit. | Corolla |
| 22. Bean shaped structure located atop the filament is called ____. | Anther |
| 23. The sticky head atop the style of the flower is called the ___. | Stigma |
| 24. Swollen cavity that contains the ovules is called the ___. | Ovary |
| 25. The outermost covering of an unopened bud is called the ___. | Sepals |
| 26. ___ is an undeveloped plant or animal. | Embryo |
| 27. What is the difference between a composite flower and a simple flower. | A composite flower is a mass of hundreds of flowers on one stalk. A simple flower is just one flower. |
| 28. Describe in great detail the pollination and fertilzation process. | Whenever pollen grains are carried from an anther to a stigma, pollination occurs. Wind, insects, birds, water, and man can cause pollination. Wind and insects, especially bees and butterflies are the most important agent of pollination. |
| 28-1. Bees and butterflies crawl into the flowers seeking nectar and pick up pollen on their hary bodies and legs. They carry and deposit pollen grains from flower to flower. | When a grain of pollen falls on the sticky stigma, it soon begins to form a pollen tube. This tube, containing sperm, grows down through the style to the ovary. Fertilization will begin when the sperm fuses with the ovule. |
| 28-2. This will cause the ovary to swell and the fertilized eggs will begin to form seeds. The ripened ovary becomes a fruit protecting the seeds within. |
