COMMON MISCONCEPTIONS
1. FLOWERS PRODUCE FRUITS which then Produce Seeds.
· The union of the female gamete in the ovule with the male gamete in the pollen form seeds. Fruits develop after to protect and in some cases disperse seeds.
2. FRUITS SOMETIMES DEVELOP without pollination and fertilization (parthenocarpy).
· It is of substantial economic importance because of the popularity of seedless fruits such as bananas and pineapples.
3. Plants CAN NOT reproduce sexually.
· Any process where 2 gametes fuse is sexual reproduction. Pollination is a common form of reproduction. In pollination the male gamete (pollen) is carried by a vector (wind, insects, birds, etc.) until it reaches the stigma of another plant. Once the pollen reaches the stigma, the female and male gametes fuse. Through the process of sexual reproduction genetically unique offspring are produced. This is a result of confusion between the terms mating and reproduction.
4. Asexual and vegetative reproduction are SYNONYMOUS TERMS.
· Asexual reproduction and vegetative reproduction are not synonymous. Vegetative reproduction involves plant parts—stems, leaves, or roots—not involved in sexual reproduction.
5. Pollen is the MALE GAMETE.
· Pollen is a multi-cellular male gametophyte.
6. POLLINATION IS NOT SIMPLY transferring pollen from anther to stigma.
· That definition inaccurately excludes gymnosperms, which have pollination but lack anthers and stigmas. In gymnosperms, pollination is the transfer of pollen from a microsporangiate, or “male,” cone to the micropyle of a megasporangiate, or “female,” cone.
7. The importance of ANIMAL POLLINATION is OVERESTIMATED.
· Our most important food crops are wind pollinated, including corn, wheat, and rice.19 Other staples in our diet are asexually propagated or self-propagated, such as potatoes, sweet potatoes, and cassavas, peanuts, soybeans, and beans
8. Pollination is NOT THE SAME as fertilization NOR DOES pollination ensure fertilization.
9. The angiosperm life cycle is often GENERALIZED to show SEXUAL SEEDS.
· In some species, such as dandelion, most seeds are asexual (apomexis).
10. Seedless fruit crops are NOT ALWAYS vegetative propagated.
· Seedless tomatoes, seedless cucumbers, and seedless watermelons are grown from seed
· The union of the female gamete in the ovule with the male gamete in the pollen form seeds. Fruits develop after to protect and in some cases disperse seeds.
