1. The Flower - Structure 1. Stamen – male organ of the plant
Two parts of the Stamen
1. Anther – produces the pollen (male gametes)
2. Filament – stalk that holds the anther
anther
Filament

2. 2. Pistil – The female organs of the plant Three Parts of the Pistil
Stigma – located on the top of the pistil; sticky to collect pollen
Style – tube-like structure that holds up the stigma and leads down to the ovary
Ovary – contains ovules; turns into fruit
Ovules – contain eggs; become seeds of the plant ;

5. Petal – Brightly colored parts of the stem to attract pollinators
Sepal – leaves at the base of the flower; provide protection to the flower before it blossoms

7. Pollination - transfer of pollen from anther (male) to stigma (female) of plant; accomplished by birds, insects, and wind
Two types of pollination
Self-pollination - transfer of pollen to stigma on the same plant
Cross-pollination - transfer of pollen to stigma in a different plant

10. Pollinators – organism that carries pollen from the anther of one plant to the stigma of another

11. Steps to make a plant embryo
Pollen lands on the stigma
The pollen tube travels down the style to the ovary
The nuclei of the pollen unite with the nuclei of the egg
The flower withers away
The ovary becomes the fruit and the ovule becomes the seed

13. D. Seed
Protected by a coat that lets the embryo survive tough conditions
Fruits help to disperse seeds away from parent plants
Seed germination – early growth stage of a plant embryo

14. Seed Germination Requires: Water Oxygen Proper Temperature
Seeds remain dormant or inactive until conditions are right for germination

17. Epicotyl – becomes the stem and leaves of the plant
Hypocotyl – becomes the roots of the plant
Cotyledon – food source for the growing plant
