Heredity Unit 1

Reviews asexual reproduction, sexual reproduction, and plant reproduction.

TermDefinition
Asexual Reproduction offspring are created from a single organism (parent) and are exact copies of that parent
Binary Fission single-celled organisms 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 the 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 and sperm) occurs within the female
External Fertilization fertilization occurs outside the female in a watery medium
Angiosperms flowering plant
Petals attract pollinators, protect inner structures
Sepal to protect and support flower from dying out
Stem to provide support, transport water and nutrients, and store water and food
Anther produces pollen (sperm)
Filament stalk holds anther up
Stamen filament and stalk (male part)
Stigma the sticky part where pollen sticks
Style the stalk that supports stigma
Ovary where fertilization occurs (pollen + egg = seed), seeds are formed, turned into fruit
Pistil female parts
Pollination the transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization, pollinators are attracted by nectar, pollen attaches to pollinator and brushes the sticky stigma
