Plant Reproduction Essay

In the late 1800s scientist, Herbert John Webber introduced the uncertain topic of cloning. He suggested that “clons[sic]” were the groups of plants that were created with any form of vegetative process, in which all of the offspring came from the same individual. This term was viewed as fact and was later adopted into the word “clone” by Charles Louis Pollard.

Asexual Propagation is the process of using plant materials such as the stems, leaves, and roots to multiply the number of plants. These plants eventually grow to be a brand new plant that is genetically identical to the parent plant it came from. In several types of plants, asexual propagation is the fastest means of new plant growth. Asexual propagation is also a good way to maintain a plant species because they are genetically identical. In this process, adventitious roots are seen in the growing cycle. Adventitious roots are those that grow form parts of the plant that they normally would not grow from. The cuttings must do

The flower dissection will allow students to learn the flower reproductive parts and their functions. By actually seeing a real life model, students should be engaged and remember this lab on future tests. Students will be able to view flower parts under a microscope so they can grasp the picture of the real life model of a plant’s ovules. This is an engaging lab for students because they get to use lab instruments to dissect and gain practice using a microscope. Learning goal 5 is practiced throughout the lab activity.

Thesis: “The Chrysanthemums” points out the flaws society has concerning gender inequality, specifically the oppression and underestimating of women. This is clear in the characterization of Elisa, Henry, and the Tinker, the symbolism of the chrysanthemums, and the motif of clothing.

This experiment, which was used to explore the Theory of Evolution created by Charles Darwin. The use of natural selection was apparent in the artificial modification of an organism's traits which aided in this investigation. Through this experiment the Wisconsin Fast Plant was used. It is a fast-growing organism developed to improve the resistance to disease in cruciferous plants. This plant aids scientist in the exploration of environmental effects on population due to the speed to which is matures and reproduces. Artificial selection was stimulated by the selection against plants with few hairs(trichomes). Trichomes create a wider variation which means it is polygenic. The plants that had only a few trichomes were

To solve this problem our group placed stakes next to each plant in the pots and used wire to provide the plants with support to grow upright and stay in place. Furthermore, to prevent crosspollination with another groups plants all of our plants where covered with pollination bags. In addition, our plants were given 1-2 inches of water constant for 29 days and place in a room that provided fluorescent light for 24 hours a day to get our plants to grow at their full potential. After a couple weeks of plant growth the flowers where then able to pollinate to perform this procedure we used a tool called a chenille rod or “bee stick” where we would lightly touch the anthers of the flowers with the bee stick and transfer the pollen on the stick between the P1 and P2 plants. During weeks 7 and 8 watering of our plants stopped to allow our plants to dry under light before the seeds can be collected from the pods. Once the seeds were ready to be collected they were harvested in dry pods over a petri dish and allowed to germinate in a filer paper within the petri dish. Once our seeds where settled in neat rows we kept it well light and moist at all times and recorded our findings (CSUF,

Fertilization in animals is similar to that in plants because its first cellcell change occurs after gamete fusion rises in the cytoplasmic Ca2+ levels as it does in animal gamete fusion. Also, the plants make a block to polyspermy, which is the fertilization of an egg by more than one sperm cell, as do the animal’s cell’s eggs.

John Steinbeck’s, The Chrysanthemums, was published in 1938 in a book of short stories, entitled The Long Valley. The Chrysanthemums has been a rather powerful draw for scholars because of its wide gap for interpretations and analysis of its main protagonist character, Elisa Allen and also the unique descriptions used to portray the deeper meaning behind the setting of the story. Themes of sexuality, oppression of women, as well as other numerous types of conflict portrayed in this rather somber short story have made it a popular study among scholars and students alike. Steinbeck also uses literary elements including a dramatic tone, rich symbolism, and personification which increase the stories feeling and value exponentially. Steinbeck

     The short story “The Chrysanthemums” shows how extraordinarily forward thinking the author, John Steinbeck, was in his understanding of the pressures that women dealt with in his time. Through the exploration and illustration of women’s emotions, Steinbeck gives us a view into the struggle of women in the early 20th century to find a place for themselves in society as well as establishing their own sexuality(Charters, 502).

A letter written by Allegra L. Fishel in 2010, this article was sent to the editor of the New York Times and is composed of comments and opinions on a previous unknown article (The New York Times).

According to The Editors of Encyclopædia Britannica, flowers, regardless of their diversity, all have a sole function; to reproduce (2017). There are two main organs that are involved in reproduction: the stamens and pistils. The stamen has spore cases (microsporangia) in which numerous microspores (potential pollen grains) can be developed. Fertilization can only occur through pollination; when the pollen grains from the anther is transferred to the stigma of a pistil. The two main types of pollination are self pollination and cross pollination. Self pollination also referred to as autogamy, is when a flower can fertilize itself because it has both female and male reproductive system. The most common type of pollination, however, is cross pollination. In cross pollination, a flower is

The monarchs brush some pollen on the underside of their body when they try to feed of the nectar producing plants. When they feed again on another plant on their journey, some of the pollen get transferred to a new plant (“Butterfly Pollination”). In this manner, pollen from the north can fertilize a flower in the south, and vice versa. This cross-pollinating phenomenon help create the natural crossbred plants. Since pollen gets transferred from and to a lot of different species of plants, it makes the possibility of new genetic mutations, and evolution of a species. It also increases the availability of essential plants across the

The short story "The Chrysanthemums" gives insight into the life of its author. John Steinbeck was born on February 27, 1902, in Salinas, California. The locale of the story is of key resemblance to the Salinas in which Steinbeck was born and bread. "Salinas was a typical American small town, [differing] only in location and a few distinctive features" (McCarthy 3). The protagonist of this story, Elisa Allen, also resembles Steinbeck's first wife. "Steinbeck probably based the character of Elisa Allen on his own first wife, Carol Henning Steinbeck. Like Elisa, Carol was a woman of considerable talent and energy who wore 'masculine clothes' and was 'strong, large-boned' and 'handsome rather than

In this process, plants are made by taking the gene trait from one plant, intentionally copying and applying it to another plant. The cells of the new plant are able to make a new protein or modify the genetic structure and function of an existing protein. This creates properties or "traits" which are not naturally occurring. The purpose of this is to increase resistance to weeds, pesticides and adverse weather conditions, such as drought, in order to amplify crop yields and mass produce fruits and vegetables which ripen and can be harvested at the same time. Farmers and industrial food companies are thriving and certainly more people are being fed, and this is a good

Humans depend on plants in numerous ways. One reason we depend on plants is for consumption. Plants have the unique ability of producing their own food through a process called photosynthesis. In this process, plants are able to produce macromolecules such as carbohydrates that cannot be produced in animals or humans. In humans, the only to gain these macromolecules is to consume plant matter, or consume plant-eating animals (herbivores).
