male
How does corn pollinate?
Corn bearing unisexual flowers pollinate by wind. The male flowers are produced at the top of the plant and the female flowers in leaf axil, somewhere at midlength of the plant. Male flowers of the plant mature first followed by female flowers. Thus cross pollination is ensured.
How is pollen transferred in marijuana plants?
Pollen is transferred in marijuana plants by the female and male plants. The female plant flowers first and then the male plant matures. When the male flower opens it sprays pollen into the female flower.
Is a plant pollinated before it is planted?
No, plants are not usually pollinated before they are planted. They survive transplantation best when they are dormant, not when they are in flower. The purpose of pollination is to produce seeds, and this is not the purpose of transplantations.
When is raccoons first heat?
Female raccoons are sexually mature at 1 year.
What result did mendel get when he allowed the first-generation plants to self-pollinate?
Gregor Mendel developed the model of heredity that now bears his name by experiments on various charactersitics of pea plants: height (tall vs. Short); seed color (yellow vs. Green); seat coat (smooth vs. wrinkled), etc. The following explanation uses the tall/short trait. The other traits Mendel studied can be substituted for tall and short.Mendel started out with plants that "bred true". That is, when tall plants were self-pollinated (or cross-pollinated with others like them), plants in following generations were all tall; when the short plants were self-pollinated (or cross- pollinated with others like them) the plants in following generations were all short.Mendel found that if true breeding Tall [T] plants are crossed (bred) with true breeding short [t] plants, all the next generation of plants, called F1, are all tall.Next, he showed that self-pollinated F1 plants (or cross- pollinated with other F1 plants) produce an F2 generation with 3/4 of the plants tall and 1/4 short.A. 1/4 of the F2 generation are short plants, which produce only short plants in the F3 generation, if they are self- pollinated (or crossed with other short F2 plants;) these F2 plants breed true.B, 1/4 of the F2 generation (1/3 of the tall plants) are tall plants that produce only tall plants in the F3 generation, if they are self-pollinated; these tall F2 plants breed true.C. 1/2 of the F2 generation (2/3 of the tall plants) are tall plants that produce 1/4 short plants and 3/4 tall plants in the next [F3] generation, if they are self-pollinated. This is the same proportion of tall to short that F1 plants produce.
In some plants the pistils don't form until a few days after the stamens do how might this plant keep a plant from self-pollinating?
For a flower to be pollinated, pollen from an anther (which is located at the top of the stamen) needs to reach a stigma (at the top of the pistle.) Some plants are genetically capable of pollinating themselves if their own pollen reaches their own stigma; some plants are not capable of self pollination under any circumstances. For plants that can genetically self pollinate, but would prefer not to, they can avoid this by having their pistil and pollen/stames mature at different times. If the stamens mature first, the pollen will be dispersed by animals or wind or whatever dispersal mechanism it relies on. Then by the time the pistil is ready to be pollinated, there is no pollen left in that flower to land on the stigma.

Why doesn't my zucchini plant grow zucchinis?
To grow zuchinis, your plant must first have male and female flowers, then the female flowers must get pollinated by the male flowers and then the baby zuchinis should start to grow. your plants are @#$%ed up or you bought the wrong plants in case you bought the right plants.... there are some natural resources your plant needs. you can take a look at the article i added in the "related links" section. I'm sure you will know how to make zucchini grow from your plant after reading this.
