Auxin hormone is responsible for elongating the cells in the shoots. It triggers the pumping of hydrogen ions across the cell membrane and altering the way gene expression occurs within the cell in a way that influences plant growth. The experiment focuses on the influence of mechanical force in influencing the direction of the plant cell elongation. Plant cells transmit mechanical force among each other. The experiment was conducted after suspecting that mechanical force guides the alignment cortical microtubules (Wayne 2010).
The experimented started by examining the non-elongated plant cells. The cells that lacked walls (protoplasts) were isolated from the tobacco plant, Nicotiana tabacum. The isolation was done through exposure of the plant cells to enzymes with the capability of destroying the cell wall. The result is a spherical plant cell. When the protoplasts were allowed to develop in the culture medium, they reformed their cell walls (Wymer & Cosgrove 1996).
To study the effects of directional forces on plant cell elongations, the tobacco protoplasts were subjected to a unidirectional force that was produced by a centrifuge. The exposure of the force was made with previous knowledge that when the centrifugation is made in low speed, it does not distort the shape or integrity of the protoplast.
The protoplasts were then immobilized ready for centrifugation. They were embedded on an agar medium that was supported by the mold. The embedded cells were spun for 15 minutes at 450 rpm in a centrifuge. After centrifugation, the already embedded cells were then cultured for 72 hours to allow the cell elongation to take place (wymer & Cosgrove 1996).
After centrifugation was over, a microtubule antibody that was fluorescently tagged was added to the protoplasts. The cells were then ...Download file to see next pagesRead More

How Do Nerve Cells Work, and Why is It Important for Psychologists to Know This
This unique attribute enables them to function as processors and transmitters of information. A typical nerve cell consists of a soma [cell body], a dendritic tree and an axon. Nerve cells connect to each other to form networks. However, it should be stated that there are variations in the structures of nerve cells in various instance.

Interspecific and Intraspecific Plant Competitions
This report aimed at determining the effects of both interspecific and intraspecific forms of competition on total yield, survival and individual growth of two plants. Several materials including plant pots, planting trays, potting soil as well as seeds from radish and wheat were used. Seeds were subjected to light and temperature controlled chambers.

Bacterial cells Quantification
Bacterial cell quantification can be done in several ways, but this experiment will be using a spectrophotometer to measure the relationship between the bacterial cell concentration and the absorbance of light. Results using known concentrations are often used to find the cell count of an unknown solution, and this is what will be achieved here.

(Ecology) Plant Competition Lab Report
Plant competition can be categorized into two types: intraspecific and interspecific. Intraspecific competition occurs when individuals of the same species compete for the same resources in a particular area (Freedman, 2011) For instance, two trees growing closely with each other or two flowers planted on the same pot will vie for the same nutrients, water, and space, reducing the amount of resources that each individual receives.

Rate of Glucose Uptake by Yeast Cells
When Benedict's reagent (Cu2+-citrate ion complex) is added to the glucose solution and then heated, a reaction occurs (Ege, 1994). In this reaction, glucose is oxidized to gluconic acid (exists as the gluconate ion in basic condition), while the Cu2+-citrate ion complex is oxidized to a red precipitate of Cu2O as shown in Equation 1.
