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 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 that holds anther up |
stamen | filament and stalk |
stigma | sticky part where pollen sticks |
style | stalk that supports female part |
ovary | where fertilization occurs (pollen + egg = seed), seeds are formed, turned into fruit |
pistil | stigma, style, and ovary |
pollination | hummingbirds, birds, bees, and bats pollinators are attracted by nectar pollen attaches to pollinator and brushes the sticky stigma |
