Sexual • Sexual Reproduction--One organism is produced by two organisms with sex cells. • The off-spring is genetically different from the parents.
Male Parts of the Flower Stamen--The male reproductive organ of a plant. Filament-holds up the anther Anther-where pollen is produced
Female Parts of the Flower • Pistil- female part of the flower • Stigma- sticky part that collects pollen • Style- carries pollen from the stigma to the ovaries • Ovaries- where fertilization takes place and where egg develop.
Haploid Cells • Haploid Cells- Cells that have half of the number of chromosomes • Pollen- sperm of the plant • Ovule- egg of the plant
Pollination • Pollination- transfer of pollen to the female part of the plant • Pollen can be transported by gravity, wind, water currents, or animals.
Sexual Reproduction • Fertilization—when sperm and egg unite. • Diploid- cells with the full number of chromosomes • Zygote--the first cell of a new organism.
The zygote form into a seed with 3 parts. • Embryo-Baby Plant (also called a cotyledon) • Stored Food-food for the baby plant • Protective Coat- Protects the embryo and its food
Seed dispersal-the way seeds get from place to place. • Ex.-Dandelion-blown by air • Ex. Berries-eaten by animals. • Ex. Burrs-cling to animals. • Germination--Series of events that result in the growth of a plant from a seed. Germination time varies for all plants.
