Heredity Unit 1
Term | Definition |
---|---|
Angiosperm | flowering plant |
Petal | attract pollinators; protects inner structure |
Sepal | protects and supports flower; keeps from dying out |
Stem | provides support; transport water and nutrients; stores water and food |
Anther | produces pollen (sperm) |
Filament | stalk holds anther up |
Stamen | filament and stock (male part) |
Stigma | sticky part where pollen sticks |
Style | Stalk that supports the stigma |
Ovary | where fertilization occurs, seeds are formed, turns into fruit |
Pistil | female parts |
Pollination | the transfer of pollen to the stigma, ovule, flower, or plant to allow fertilization |
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 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 occurs within the female |
External fertilization | fertilization occurs outside the female in a watery medium |
