* Chose a female parent; chooses a male parent; pollen is collected from the stamens and dusted onto the female parent stigma; pollen fertilizes the eggs. The ovary develops into the pod and eggs develop into the peas; when peas are planted they develop into pea plants.…
To begin the fast plants experiment, each group received the F1 generation seeds for their designated phenotypes. After receiving the seeds, the seeds were then planted into Styrofoam “quads” allowing the seeds to germinate. The seeds were then allowed to grow under a fluorescent light bank for 5 weeks. Throughout the growing of the seeds, each plant was continuously watered and adjusted the light bank to help the plant grow more efficiently. After letting the seeds germinate for approximately 14 days, after two or three flowers had opened, a bee stick was used to transfer pollen from one plant to another. Each group then used the bee stick again 2 and 4 days after the initial pollination. Once all of the transferring was complete, each unopened bud on the plants were pinched off. Approximately 21 days after pollination, the seeds were ready to be harvested. Each quad was removed from the watering tray and allowed to dry for 5 days. After the plants were dry, each group removed the dry seedpods from the plant. We then removed the seeds from the pod. To start the germination process, a moistened piece of filter paper was placed into a petri dish. 40 seeds were neatly placed into each petri dish until there were no seeds remaining. Once all the seeds were placed in the petri dish, the petri dishes were placed in a plastic bag and set to germinate for approximately 48 to 96 hours in the window at room temperatures.…
Plants don’t produce nectar and delicious fruit just to be nice. As you will learn, bees and other pollinators play a critical role in helping plants to reproduce. Fruits play a role in allowing plants to spread to new locations.…
Plants reproduce by pollination, also called fertilization, which is the transfer of pollen from an anther to a stigma. A pollen grand produces a pollen tube. Eventually sperm will be discharged near the embryo sac and pollen develops. Products are seeds and fruits. Another way to reproduce is self-fertilization, which unfortunately is difficult for most plants due to…

Plea bargaining is a very familiar process in our criminal justice system. Usually, the defense is allowed to bargain with a prosecutor to have a defendant plead guilty to a criminal accusation with the hope of getting a lighter punishment. The problem with this immediate approach is that dangerous offenders are pleading guilty to small misbehavior charges and they are keeping a cleaner record than they should have and getting reduced sentence. Plea bargaining is needed on the other hand defendants tried on felony charges should not be able to appeal down to small misbehavior charges.…

Honey bees has been considered a beneficial introduction; it distributes as a pollinator and the provider of the hive products. Some scientist has questioned the environment role of bees outside of their natural state or range. Majority of plant species are used by honey bees, which set some high potential disturbance for pollinator relationships. Honey bees do not necessarily harm plants: they are also unlikely to enlarge hybridization of native flora. Honey bees usually use a small proportion of plant species. Honey bees are more likely effective pollinators of native plants than other bees. Many plant species are used by honey bees, which means that there is a high potential for disturbance of pollinator/native relationships. Negative…
A potato plant starts as a lateral bud (seed) under the soil. In favorable conditions, a shoot grows out from the bud vertically, which then becomes the stem of the plant above…
Gardenia's roots go back to Singapore where, in 1978, it began as a humble in-store bakery. Increasing demand led to the opening of Gardenia's first-commercial bakery at Pandan Loop in March 1983. Gardenia has since been the market leader in Singapore and has expanded its operations in Asia to countries such as Malaysia and Thailand with the latest in the Gardenia chain of bakeries here in the Philippines.…

Seeds evolved between the vascular plants and provided a means to protect young individuals. Flowers, which are the most obvious characteristic of angiosperms, guide the activities of insects and other pollinators so that pollen is dispersed rapidly and precisely from one flower to another of The same species, thus promoting out crossing. Many angiosperms display other modes of pollination, including self-pollination.…
