Dry Phaseolus Vulgaris In Navy Beans

508 Words3 Pages

Methods
Dry Phaseolus vulgaris (Navy beans) were purchased from the local grocery store. A handle full of beans were sifted through to remove any beans that were damaged or halved. The beans were then filtered by size to remove beans smaller or larger than 1.5 cm. Removing the abnormal beans lessened the possibilities of variation in plant growth. The remaining beans were soaked in room temperature mineral water for 1 hour to accelerate germination. We soaked over 15 beans with the knowledge that the beans could split again after being soaked. After the soaking process was complete six beans were chosen for planting.
In preparation for planting, two 8 oz. plastic cups were utilized for the control and experimental groups. For adequate drainage the bottom of the each cup was punctured three times. The cups were then filled with approximately 4 oz. of the soil provided to us for this experiment. Three beans were placed in each cup of soil 1 in. deep and 1 in. apart. After planting and gently covering the seeds, the soil was moistened with 1 oz. of distilled water. We printed a 27 cm ruler and taped it to the inside of each cup for accurate measuring. The cups were placed in a window sill with sufficient access to sunlight. The window is fitted with a …show more content…

Previous experiments on the subject carried out this procedure once or twice a day. We conducted this process once a day at 9 a.m. to observe how the smallest amount of stress altered the plant’s development. Nitrile gloves were worn during the encounters to reduce any chemical exchange between the hands and the plant surfaces. After measurements were recorded, each plant was watered at the base of the shoot with 0.5 oz. of distilled water. None of the leaves came in contact with the water to ensure that the plant’s responses would only be affected by touch. The plants were then returned to the window

Douglas-fir and red alder have seeds that use wings, signifying the use of the wind as a method of seed dispersal. Both trees have seeds than are covered in a seed coat and have nutrient reserves. Gymnosperms, however, have a large megagametophye, which is the haploid nutritional tissue. Angiosperms typically have a smaller megagametophye, that later develops into an endosperm (red alder, however, does not have an endosperm). When seeds germinate, general 4 steps usually occur first: 1) Imbibition, when seeds swells with water and the seed coat ruptures 2) Metabolism increases.

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.

The data observed and recorded in this lab shows that the concentration of miracle gro’ does affect the growth rate and germination speed of black eyed peas. The data is shown through two graphs and two data tables. The control group in this experiment is the seeds with a 0% concentration of miracle gro’, therefore the seeds with just water. The experimental groups are different concentrations of miracle gro’ including a 10%, 15%, 20%, 25%, and 30% concentration. The variable in this experiment is the amount/concentration of miracle gro’.

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.

The beans that were selected must have been completely whole with no dents or abrasions. Five beans were placed in each section of the plastic container which means there were 20 beans in the two plastic containers. Then 12 female Callosobruchus maculatuss were sucked out of the main plastic container using an aspirator which was designed to suck in each Callosobruchus maculatus. The females were then separated into two groups of six and a group of six female Callosobruchus maculatuss was inserted into each plastic container. The same process was then repeated but for six male Callosobruchus maculatuss.

Even though there’s very little mention of windows, they still represent her ignorance to the situation. She says “but Louie’s cousin said he was gonna make us walk home if we didn’t stop playing with the windows (24).” This is kind of ironic seeing as they did end up walking home but it was because he ended getting arrested. Later it says that the waved at him goodbye through the cop car.

Today, most homeowners prefer using Impact Resistant Single Hung Windows for their homes because they can easily fit any opening. They are rectangle shape windows that are set vertically in a home. These windows have a movable lower sash and a fixed upper sash. To allow free air to enter the rooms, you can raise the lower sash. Also, the sash can be tilted to clean the windows from the inside.

As Geyh argues in her essay, the window is the boundary of the house, which simultaneously separates and connects the inside and the outside (111). By turning the light on, it goes dark; “[f]unctioning as a mirror, it creates a circle of inwardness” (111). It sustains the illusion that what is inside is the only reality that exists, since the outside is no longer visible. The window then emerges as a separation tool from nature outside rather than a means of

Although there were no major set changes, the piece created to mimic a house in Indiana seemed quite accurate. In this show, it's incredible how such a simple set piece functioned in so many different ways. As the characters moved from the living room to the ¨kitchen¨, functioning doors and sound effects created a realistic environment for the characters to perform in. Furthermore, the window in the house was a necessary component when cottage cheese rained down on William´s potential boss in one of the final scenes. Without the window in the set, this scene would become impossible and unrealistic.

In the sixth step you will want to fill the graduated cylinder again, but this time with 23 mL and evenly water the pot labeled experimental group. Once both pots are watered for step seven you will want to go place both plants on the same window ledge so they have exposure to the same amount of sunlight. Everyday you will continue to water your plants in the same order as steps five through seven. Once you begin to have growth in your bean plant you will then conclude step eight which will be, take a ruler using the centimeters measurements, measure the growth of your plant, the height. Step nine will occur when you are done collecting data then at that point you will record your data in your notebook, computer or where you are recording your

After this encounter, she looks out of the window to attempt to see who was knocking at the door. Cieraad (1999) describes the importance of the window, and what the window represents to the home. Windows can be portrayed as a transparent border that separates the inside and outside realms, disconnecting the private home to the public world. She notes how houses in the 18th Century had large sash windows. These act as a visible barrier between the home and the outside world.

Because Esperanza is capable of finding love as she says, the window acts as a device that she can direct her hope through. While fantasizing about a different life, “away from Mango Street”, Esperanza describes a house that she would find nice, a house with “flowers and big windows … [that] would swing open, all the sky [coming] in” (Cisneros 82). Esperanza isn’t content with her current life and wishes for a life with something more, a life with a house to call home. The windows that bring in the sky in Esperanza’s dream home act as a symbol for significance in life, the windows are big because they are part of Esperanza’s hopes that she has been dreaming of through windows and the sky coming in represents Esperanza being wild and free from the bounds of her current unsatisfactory environment. Windows symbolize the novel’s theme of struggling to attain a gratifying life by acting as an object for the characters to direct their hope
