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. |
