Seeded Plant Reproduction

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.
