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 |
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. |
external fertilization | Fertilization occurs outside the female in a watery medium |
Angiosperms | Flowering plant |
Anther | Produces pollen (sperm) |
Filament | Stalk holds anther up |
Stamen | Sticky part where pollen sticks |
Stigma | The part of the pistil where pollen germinates. |
Style | Stalk that supports |
Ovary | Where fertilization occurs (pollen + egg = seed), seeds are formed, turned into fruit |
Pistil | The female reproductive part of a flower |
Pollination | when bugs take pollen between flowering plants of the same type. The pollen fertilizes egg cells to make seeds. |
