Auxin the is the primary growth hormone that is also known as Indoleacetic acid ( IAA). It promotes primary growth in plants by promoting cell elongation through inducing the rate of cell division, and by doing so increasers apical dominance. Apical Dominance which means the apex of the plant is dominant over the other parts of the plant, therefore majority of the growth is in the tip of the plant.
The concentration of Auxin in the plant is dependant of the response to directional stimuli. The concentration of auxin in different parts of the plant cause different reactions. In shoots, when auxin concentrations are high, it promotes cell elongation, which mean the he darker side of the shoot elongates and grow towards the light while In roots,when auxin concentrations are high, it inhibits cell elongation which means the darker side of the root becomes shorter and the roots grow away from the light.The response of plant due to the change in auxin based on directional stimuli is called tropism. Tropism in plants is categorized into three major categories; Phototropism, Geotropism, hydrotropism.

Cytokinins promotes cell division by utilizing the stage cytokinesis in cell division to promote equal growth of both the root and the shoot. The growth of the shoot and root is dependent of the ratio of cytokinins to auxin. If there is an increase in cytokinins then the shoot forms and if there is a decrease in the cytokinins then the root.Cytokinins also promote secondary growth in plants. Secondary growth plants is seen in the increase in the vertical growth of the plant by the diameter or the branching of new branches. A commonly used function in the real world of cytokinins is that it delays the aging of plants, by increasing the amount of new proteins in the plant. Thus cytokinins is sprayed on flowers to keep the flowers fresh and alive for
Lima bean number 1 germinated but did not thrive. My plant was a yellow color with few leaves. Though my plant was very tall it was weak and could be broken easily. The plants in uv light were of a dark green color whereas my plant was yellow. In addition the leaves of my plant were very small.
As a result, plants have adapted ways to protect themselves against their natural predators by implementing “defense mechanisms”. Such adaptations may be structural or chemical, where structural mechanisms are simply parts of plant structural arrangement, such as thorns. Chemical defense mechanisms are more complex, and involve production of retarding chemical compounds and toxins. These volatile compounds are often released when the plant is damaged, and have physical effects on the predator.
Something I learned about in Herbology 301 is healing. Healing is an important part of our life, which is why i wanted to write about it. Healing spells are needed in everyday life, and if we were to ask someone how many healing spells they 've used in their lifetime, the number would probably be too high to remember. I also learned that mental illnesses are not one-spell-cure-all diseases, which is very helpful to know.
In Yellow Wallpaper,The Chrysanthemums and Boys and Girls women/girls role in society is often limited. In yellow wallpaper John’s wife is suffering from postpartum depression. John does not let her do anything even write in her diary or read. In chrysanthemums Elisa is the best at what she does which is planting chrysanthemums. A guy came to Elisa in a wagon and told her i travel and fix pots for a living.
Doriana Spurrell What different frequencies and types of light would prompt the Spinach leaves to go through the process of photosynthesis effectively? Purpose: The purpose of this experiment was to see which of the four lights that range across the light spectrum would properly and most efficiently help the spinach leaf perform photosynthesis. Background Information: Photosynthesis is the process in which plants use light energy to transform into chemical energy.
In John Steinbacks “The Chrysanthemums,” the shift of the setting from the ranch to the road plays an important role in the development of the main character, Elisa. Therefore, in the first setting, Elisa is in her garden attending to her the chrysanthemums, which she loves and cares for. Immediately, we’re placed in a rural setting, where women happen to live in isolation and man is manly. Elisa sneaks quick glances towards the men by the tractor shed, who is talking to her husband, waiting for them to leave, so she can throw aside her gloves and work her fingers into the soil of the garden. However, Elisa shows her fearless side by quickly digging in the garden, with her eagerness to grow her chrysanthemums, right after the men leave.
In The Bean Trees by Barbara Kingsolver, Missy, The novel’s main character changes. Said changes are what defines Missy as a whole.

Such obstacles drive on these changes through either fear or just a lack of will, suppressing her mind and then being confronted with a need for change The reader can see Missy’s first transition when she has a change of heart in the people of Pittman County.
The Sign of the Chrysanthemum- Katherine Paterson The novel The Sign of the Chrysanthemum by Katherine Paterson is a story a sef boy named Muna who runs away from his manor to the capital city of 12th century feudal Japan, Kyoto, in search of his samurai father. I will discuss the primes of social structure and politics. Katherine Paterson’s The Sign of the Chrysanthemum accurately portrays the Heiji Disturbance and the status of craftsmen and ronins.
There are many symbols in A Raisin in the Sun worth describing, but one that particularly stands out is Mama’s plant. It is old and barely a substantial piece of nature, yet it makes many vital appearances in the play. The small plant seems to personify Mama’s stubborn nature in its intent on survival despite its close to death appearance. It also represents Mama’s dream that seems close to being crushed, yet never dies. As a whole, the plant is an extension of Mama’s character and an important symbol in the play.
The setting shapes the mood and tone of a story and has a great affect on what happens in a story. The setting influences the events that take place, how the characters interact and even how they behave. Settings show where and how the character lives, what they do, and what they value. Characters have a relationship with the setting just as much as they do with other characters in the story. This is seen in the effects the setting has on the development of the Character Elisa in the story “The Chrysanthemums.”
This root tip was choosen because of its rapid growth and it can be easily avaliable and grown in large numbers. The rapid root growth proved advantageous as it allowed the observation of multiple cells in each mitotic stage within a small sample. It was expected that the majority of the cells found would be in interphase as a large proportion of the cell division cycle is spent with the cell performing its normal cellular functions. Materials: The Materials required for this experiment include; a
The answer- plants have developed many important behavioural and physiological methods not shared
Research Question: How does the presence of light impact the rate of transpiration in plants? Aim: The aim of this experiment was to investigate how the presence of light affects the rate of transpiration in plants. Hypothesis: As light intensity increases, the rate of transpiration (water uptake) in a plant increases.
This experiment is an attempt to investigate the amount of water potential across root storage plant species. The root storage plant species that shall be used are the carrot and the potato and the method that shall be used is known as Chardakov’s method. Water potential is the tendency of water to enter or leave a cell. Water moves from an area or region of low water potential to an area of high water potential. It is important to note that the highest water potential is 0(the water potential of pure water) and the other water potential values are in negative numbers .
Introduction Plants are a major necessity in the balance of nature, people’s lives, and our terrain. We may not realize it, but plants are the ultimate source of food for almost 95% of the world population so says the National Group of Food. It’s a fact that over 7,000 species of plants are being consumed today. Plants are one of the reasons that we get clean water; as they help regulate the water cycle.
