Reproduction
Term | Definition |
---|---|
Asexual reproduction | One parent Identical DNA Types Binary Fission Budding Fragmentation/ Regeneration |
Binary fission | Under ideal conditions, bacteria grow very rapidly: some double in number every 20 minutes. Usually some nutrient runs short, or waste material builds up, and growth ceases. |
Budding | an offspring grows out of the parents body. Not an equal dividing like binary fission |
Fragmentation/Regeneration | offspring form out of broken off pieces of the parent |
Sexual reproduction | he 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 | A Flowering Plant |
Petals | Attract pollinators, protect inner structures |
Sepal | To protect & support flower, keep from drying out |
Stem | provide support; transport water & nutrients, store water and food |
Anther | produces pollen (sperm) |
Filament | stalk holds anther up |
Stamen | Filament & stalk (male part) |
Stigma | sticky part where pollen sticks |
Style | Stalk that supports the stigma |
Ovary | Grows fruit out of |
Pistil | Female parts |
Pollination | The transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization. |
