Question | Answer |
---|---|
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 parents body. Not an equal dividing like binary fission |
Fragmentation/Regeneration | Offspring form out of broken of 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 |
External fertilization | Fertilization occurs outside the female in a watery medium |
Angiosperms | Flowering Plants |
Anther | produces pollen (sperm) |
Filament | stalk holds anther up |
Stamen | Filament & stalk (male part) |
Stigma | Sticky part where pollen sticks |
Style | Stalk that supports |
Ovary | Where fertilization occurs (pollen + egg = seed), seeds are formed, turning into fruit |
Pistil | The female organs of a flower, comprising the stigma, style, and ovary |
Pollination | The transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization |
