Heredity Unit 2
Everything about heredity ranging from eye colours to plant organisms.
| Term | Definition |
|---|---|
| Asexual reproduction | Offspring are created from a single organism (parent) and are exact copies of that parent. |
| Binary fission | Divide into two identical cells. |
| Budding | An offspring grows out of the body. Not an equal dividing like binary fission. |
| Fragmentation/Regeneration | Offspring form out of broken off pieces of the parent. |
| Sexual reproduction | The genetic information from two parents is combined to create offspring with unique genetic traits. |
| Internal fertilization | Fertilization (egg + sperm) occurs within the female. *except for seahorses. |
| External fertilization | Fertilization occurs outside the female in a watery medium. |
| Angiosperms | Flowering plant |
| Anther | Produces pollen(sperm) |
| Filament | Stalk holds anther up |
| Stamen | Filament and stalk(male part) |
| Stigma | Sticky part that pollen sticks to |
| Style | Stalk that supports |
| Ovary | Where fertilization occurs(pollen + egg = seed) seeds are formed/turned into fruit |
| Pistil | Female part |
| Pollination | When animals pick up pollen from a male plant and carry it over to a female plant. |
