60. a) Flowers are developed in order to reproduce and flowers help by attracting animals to pollinate. Pollen are for males, and seeds are for females. The seeds are coated with a hard outer layer to protect it and fruits are made so animals can eat them and the seeds will spread by the means of their feces. Seeds can also be dormant for a long time.…
Plant sexuality has a wide range of topics about sexual reproduction systems found across the plant kingdom. Flowers, which are the reproductive units of angiosperms, amongst all living things are physically varied the most. They also show the greatest diversity in methods of reproduction of all biological systems. The system for classifying flowering plants was proposed by Carolus Linnaeus, which is based on plant structures. Plants employ several different morphological adaptations that involve sexual reproduction. Christian Konrad Sprengel studied plant sexuality, which brought understanding to the pollination process. This process involved both biotic and abiotic…
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.…
After driven by a storm through rough seas, we discover the land of the Lotus Eaters, people who devour the lotus: fruit and flower. We dispatched onto the coast of the land and mingled with the natives. No direct threat to our men, our warriors, purely the lotus to eat. The Lotus Eaters told us of the delicacy, how fortunate we would be if we took a bite of just a little bit. Only one man did not eat the saccharine flower. We immediately forgot about our wants to return, our only thoughts being to consume the Lotus.…
Susan really wanted to see a specific orchid the Polyrrhiza lindennii, this orchid is considered a ghost orchid which is leafless and was names in honor of the Belgian plants man Jean-Jeles Linden. Susan states “If the ghost orchid was really only a phantom it was still such a bewitching one that it could seduce people to pursue it year after year and mile after miserable mile (40)”. This statement shows that although this specific plant is so hard to find people cannot resist the temptation of setting out to find…
Primary consumers (herbivores) feed directly on producers. Secondary consumers (carnivores) feed on primary consumers. Consumers that feed on both plants and animals are called omnivores.…
Michael Pollan’s film, The Botany of Desire, opened my eyes to the complicated relationship between people and plants. Pollan opened up with the following statement: “Flowers. Trees. Plants. We 've always thought that we controlled them. But what if, in fact, they have been shaping us?” (Pollan, PBS) I paused the film and took a few minutes to let this soak in. I was always under the impression that we were manipulating plants to our benefit only. I never thought that the plants were gaining something as well. The narrator explains, “The Botany of Desire examines this relationship by telling the stories of four plants that ensured their survival…
When man first saw a flower he did not understand its presence. Then as flowers grew we understood not only its beauty, but other values such as scent and aroma. It was learned through an unconscious process. The Botany of Desire examines “connecting fundamental human desires for sweetness, beauty, intoxication and control with the plants that satisfy them – the apple, the tulip, marijuana, and the potato – The Botany of Desire intends to show that we humans don 't stand outside the web of nature; we are very much a part of it” (PBS.Org). “I call this book The Botany of Desire because it is as much about the human desires that connect us to these plants as it is about the plants themselves”(Pollan,…

species have provided valuable insights into angiosperm (flowering plant) genome structure, function and evolution. For example, A. thaliana has experienced two genome duplications since its divergence from Carica, with rapid DNA sequence divergence, extensive gene loss and fractionation of ancestral gene order eroding the resemblance of A. thaliana to ancestral Brassicales1. Compared with an ancestor at just a few million years ago, A. thaliana has undergone a ~30% reduction in genome size2 and 9-10 chromosomal rearrangements3,4 that differentiate it from its sister species Arabidopsis lyrata. Whole-genome duplication has been observed in all plant genomes sequenced to date. A. thaliana has undergone three paleo-polyploidy events5: a paleohexaploidy (γ) event shared with most dicots (asterids and rosids) and two paleotetraploidy events (β then α) shared with other members of the order Brassicales. B. rapa shares this complex history but with the addition of a wholegenome triplication (WGT) thought to have occurred between 13 and 17 million years ago (MYA)6,7, making 'mesohexaploidy' a characteristic of the Brassiceae tribe of the Brassicaceae8.…
The political party of the Federalist believed in a loose interpretation of the Constitution, however, the Democratic-Republicans believed in a strict interpretation. Alexander Hamilton, the leader of the Federalist party, believed that loosely interpreting the Constitution would help our new country prosper. Thomas Jefferson and James Madison, leaders of the Democratic-Republicans, believed that strictly interpreting the Constitution would protect our nation. Both had different views of how to help America great. They may have fought over a several different matters, but they were both fighting for the same thing. The Federalists and the Democratic-Republicans had very different ideas as to how to make America thrive.…
In “The Lotus-Eaters”, Odysseus’ men show temptation. They come upon an island with lotus plants and there are consequences for eating these plants. “. . . those who ate this honeyed plant, the Lotus, never cared to report, nor to return: they longed to stay forever, browsing on that native bloom, forgetful of their homeland.” Eating the lotus plants makes the men forget about all their troubles. Previous to this event, they endure ten years of searching for a way back to Ithaca. The sweet smell of the lotus, along with forgetting about their troubles, tempts Odysseus’ men into eating the plants. Odysseus eventually retrieves all his men, but this results in frustration because the men delay his journey home.…
French broom can easily be identified by its distinct features and behaviors. It is identified by its silver haired stems and leaves arranged in a trio, and it can grow up to 16 feet tall (“Broom”). The invasive plant can live up till 15 years, making it a very long-lived plant. The most problematic part of the plant are the seeds, as they are very plentiful. These seeds are prone to spreading a great deal, which causes rapid reproduction. Modern studies show that…
Tom had always loved plants. He loved the way they would begin their lives as tiny seeds buried in their cosy little nests, and then, with all the essential ingredients a sprinkle of water, a cup of sunlight and a dash of time they would blossom into sharp Italian ballet dancers, their lively radiance beating against the cream-white window pane. Toms mother would grow these plants by the dozen, and, once a month, after harvest week, she would take all the plants away, replacing them with seemingly barren pots of soil, each containing their own hidden seed ready to grow and blossom into another magnificent dancer on the windowsill.…
