Document Summary

Part of the information is contained in the textbook; the rest comes from lectures. Pollination of plants in the ower ovary, the nucleus of the pollen grain unites with the nucleus of the ovule. This is fertilization! transfer of pollen grains (male gametes) from anthers to stigmas pistil = innermost part of the ower, female sex organs consisting of the stigma, style & and ovary. Reproductive organs of flowering plants gametes male reproductive cells of plants anthers male reproductive organs of plants stigmas sticky organ, female. Style tube that travels down to the ovary. Types of reproduction in flowering plants (contains the eggs) Pollen grains travel down the style to fertilize ovules. Self-fertile or self-compatible: can pollinate themselves, but bene t from insect visits i. e. peaches! Self-infertile or self-incompatible: need cross-pollination (pollen is transported to a ower of a different plant of the same species)
