Male Reproductive Structure
The stamen consists of two parts: Anther and Filament
The filament is a stalk that supports the anther

Female Reproductive StructureThe pistil consists of
the stigma, style and ovary
The sticky stigma receives the pollen from the anther
The pollen grows a tube down through the style

Pollination
Wind, insects or other animals transfer pollen from the anther of one flower to the stigma of another
Flowers vary depending on pollination mechanism

Fertilization
After pollen lands on stigma, a pollen tube grows down through the style to ovary
![Page 8: Plant Reproduction adapted from fa/WebImages/FA_HTMLs/newitje/prepro. ppt](https://reader036.vdocuments.net/reader036/viewer/2022062810/56815bef550346895dc9e0c6/html5/thumbnails/8.jpg)
Seed and Fruit Development After fertilization,
the petals and sepals fall off flower
Ovary “ripens” into a fruit
The ovule develops into a seed

Seed Dispersal Mechanisms-Allow plants to colonize new areas and avoid
shade of parent plant
Wind Dispersal - Flight mechanisms, like parachutes, wings, etc. Ex. Dandelion, maples, birch
Animal Dispersal - Fleshy fruits which animals eat, drop undigested seeds in feces or burrs which stick to animals’ coats

Gravity Dispersal - Heavy nuts fall to ground and rollex. acorns
Water Dispersal - Plantsnear water create floating fruitsex. coconuts
