Life Cycle of a Plant, Dominant and Recessive Traits

In a plant’s life cycle, there are a few key details such as germination, growth, egg or sperm production, pollination, seed production and dispersal, and finally death. In the germination phase the seed sprouts after a certain exposure to light, temperature, and moisture (Pima Community College). In the growth stage the sprout turns into a mature plant, this is followed by the production of an egg or sperm and then pollinated by other pollen transferred by the wind or an animal. Next is the seed production when the embryo and endosperm get a seed coat to form a new seed, the dispersal of the seed occurs it is transferred from the parent by interaction with an animal. Finally death, it’s pretty obvious, death is when the plant dies.

In the novel, The Botany of Desire, Michael Pollan tells the intriguing story of how plants are domesticated from the perspective of the plant with regards to four specific plants.. The four plants he chose for discussion are the apple, the tulip, marijuana, and the potato. As he discusses the domestication of these plants, his overall focus is the desire that each of these plants have to us as humans. Pollan has written books and magazine articles among other pieces of literature that discuss the relationship between plants and humans. Throughout this informational text, Pollan tries to keep the perspective from the “plant’s-eye view of the world,” but he often slips into Pollan’s eye view of the world. As he talks about experiences that he has had with each of these plants and gives a little bit of their history, it was often hard to stay focused on the topic that he was trying to convey. However, I found that the perspectives that Pollan brings up are interesting to think about. The Botany of Desire was an interesting journal type informational novel that didn’t quite live up to my expectations of what it could have been.

The germination process begins when water and oxygen are pulled into the seed by the seed’s coating. The embryo’s cells grow bigger as water and air

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

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

At about day 14, two or three flowers open on most plants in which one begins pollinating as followed. Simply use a small fine tipped paintbrush and cross-pollinate all four plants with each other. Repeat the same step, in four days going. After the third pollination carefully remove all unopened buds by pinching them. Take away all new buds for the next two weeks or as necessary. Seeds are now ready to harvest after about 21 days after pollination. Carry the quads with plants away from the watering try while letting them dry for five days. Remove dried seedpods from the quads and roll them between your fingers to free the seeds from the pod. Count and store seeds in an envelope, labeled with your name and

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,

Stage eight occurs on days eighteen through twenty. During this time, seed pods will develop. The final stage is stage nine, which occurs on days twenty-one to forty. This will be when the Fast Plant begins to wilt and die, and its seed pods will begin to become dry and eventually and await planting. Then the entire life cycle will begin all over again.

In general terms, explain how the basic plant life cycle with alternation of generations is modified in angiosperms.

Human cells carry two copies of each chromosome they have two versions of each gene and the different versions are called alleles. Alleles can be either dominant or recessive. Dominant alleles means you have one copy of the gene or your heterozygous. Recessive alleles means you have two copies of the gene or your homozygous.

The cycle works in a very basic way. First, carbon is taken from carbon dioxide found in the air. Plants take in carbon dioxide from the atmosphere. Plants absorb carbon dioxide from the atmosphere and use it, combined with water they get from the soil, to make substances they need for growth. The carbon is then mixed with water. Carbon dioxide is then formed into sugar (glucose). The process of photosynthesis incorporates the carbon atoms

Just like everybody else in the novel Benjamin Rand’s takes the words of Chance when he talks about the garden and uses that as a huge metaphor about being a productive businessman. Ben Rand being the very best businessman that he is interprets what chance is saying to exactly what a productive businessman would need to do but the meaning to what Chance was saying has a little different meaning to what Ben thought. Chance is saying that when plants are like people, he really means that they start as a sprout and they grow to either become a flower and plant or a tree, and when they times comes from the sprout to die it will die peacefully after it has done all of its duties to why it was made. The sprout cannot do it on its own though. The

They sprouted, then opened out in a studied and careful program of increments. Now that was astonishing, all those compressed unfoldings and burstings, but no one said so. No one made a fuss when the seeds actually performed: sprouts, leaves, the long rivery stems, and finally the intricacy of blossoms. I liked to tear the silk of the petals between my fingers, rubbing the pollen into my hands. But that isn’t nice, Reta, my mother said.

     Photosynthesis is a reproductive system that occurs in plants. The main components required for photosynthesizing are sunlight, energy, water and mineral from soil, and carbon dioxide from the air. Once these components are combined they
