Taxol’s Effect on Rates of Tip Growth and Nuclei Position in Neurospora Crassa

In this experiment we are testing the effect of fertilizer on the speed of plant growth. We prepared a 4 quad cell, 1 control group and 3 experimental groups. So, we had one with no fertilizer, one with three seeds of fertilizer, one with six seeds of fertilizer, and lastly, one with nine seeds of fertilizer. The plants that we grew were called Wisconsin Fast Plants, members of the crucifer family. These plants are small and easy to grow, but for optimal growth they require continuous fertilizer, water, fluorescent light, and temperature between 18 degrees Celsius and 26 degrees Celsius 24 hours a day. Fertilizers are substances that are put into soils to increase the growth of the plant. There are two different types of fertilizers, synthetic

In this experiment first the stages of an onion cell undergoing mitosis are going to be observed and every stage is going to be detected and drawn on paper. A brief description to what is going on should be attached to the pictures. This is important to understand the basics of cell division which is necessary growth,repair and asexual reproduction. Second the number of cells undergoing each phase is going to be counted to figure out in which phase the cell remains the most. If interphase is the stage in which the cell grows and prepares for cell division then the

On average the caffeine had a bigger effect on the head portion of the planaria compared to the tail. However these results are not constant throughout, as there were major fluctuations in the rate of growth. This might have happened due to the amount of food the planaria were eating compared the caffeine uptake. Also it could be due to a mistake in the recording of the planaria length. This is due to the planaria curling up in size for them to save their energy so they could continue to live. Due to the data being recorded before feeding them, there is the possibility that the planaria were not stretched out to their full size. These results were not expected and do not support the hypothesis as it was hypothesised that the 0.00001M solution would have the greatest effect on the planarian’s rate of growth. In comparison to other similar experiments, these results are slightly different. The other experiment had a major increase over the first few days, however it started to level out after the last few days the planaria were given caffeine. This is similar in this experiment however there was a decrease on the fourth day on the head and on the third day for the tail. This might be due to the other experiment having more planaria to test on. Possible limitations for this experiment are the amount of food the planaria had

This paper explores a regional issue of White-Nose Syndrome in bats throughout Missouri. Left untreated this fungus could cause several endangered bat species to become extinct. There are several new experiments to see if we can control the spread of White-Nose Syndrome including exposing bats to a bacterium, creating man made hibernation stations or other changes within the bats makeup. The best results we have seen so far must go back to the preservation of a banana. This bacterium may be the best way to preserve our current way of life without hopefully changing to world around us greatly as well.

Using the microscope provided to analyze the different size of the different cells and organisms

Describe the process of germination and plant growth you observed in the lab activity for a dicot plant.

The mysterious phenomenon known as white nose syndrome has only been around for 11 years, yet it has had a devastating effect on the bat population. White nose syndrome is a disease which kills hibernating bats, named because of the white fungus coating the muzzle of its victims. Of the over 1,000 bat species in the world, only 7 species seem to be affected by white nose syndrome. This disease can wipe out 89 to 99 percent of a colony, and has already killed more than 5.7 million bats in eastern North America; it shows no signs of slowing down or stopping. The Richmond guarantee would be the perfect opportunity to help contribute to research for white nose syndrome.

To start new laws and community would need to be put forth to ensure that the Indiana bat is not disturbed during their hibernation in caves. One way to complete this is by working with the local government to install gates to block access to the caves when the Indiana bat is hibernating. Another way to help ensure the survival of this species would be to put forth community education to help raise funds and awareness in finding cure for the white-nose syndrome (Animals-Moms.me 2016). I do not believe that these change would not require that much sacrifice from us humans in order to ensure the survival of this species. I do not believe the extinction of this species would have a large negative affect on humans, but seeing as it is one of many species of bat’s currently affected by the white-nose syndrome. With this issue in mind the extinction of this species could cause a large misbalance within their

Fieldwork was done within or on the periphery of Fort Collins, Colorado. The elevation in Fort Collins is 1,525M. The climate is temperature and semiarid with a 4-season cycle, averaging 300 days of sunshine. During the winter month, temperature are -2 °C. Summertime it is 22 °C. The big difference can affect the hibernation of the bats. The ArcView was used to survey and analyze the different areas used in the study. A fragmented forest was used in the experiment because it is a big brown bats most preferred habitat. The fragmented forested area was development free that has a least 20-30% of fires. In fragmented areas, it is in a stage that contains decent number of pine snags

Repeat steps 1-5 with 5% concentration of sodium chloride (use mass balance to find 5%)

It is caused by a white fungus that grows on their nose and wings.White Nose affects hibernating bats. It’s named after the fungus that grows on the bat’s nose. White nose has been spreading like wildfire through Eastern North America and Canada since the first record of it in 2006-2007 in New York. White Nose causes the bat to fly around in winter when they should be hibernating. There has been 5/7 million deaths of bats caused by White Nose. There are many organizations that looking for a way to stop White Nose. One is White Nose syndrome (WNS). They take many tests to try to find out more about White

Observation of phenotypic appearance was taken using a dissecting microscope at 50x magnification and a

Making the onion tip root cell slide was successful. Our results supported the hypothesis because we saw cells in the onion root tip in prophase, metaphase, and anaphase. As we went up in power objectives, each phase of the cell became more definitive. The cell root was a great indicator of the structures of the different cycles of the cell. This is important because we will be prepared for future labs working with the microscopes and can now adjust it for the best view of the slide. We practiced working with the compound light microscopes and different phases of the cell cycle. Onion root tips are useful to observe mitosis because the cells are frequently diving as the root grows. So when we stained the cell, we caught many cells in different phases. The significance of this lab was to better understand the process and stages of mitosis and meiosis and compare and contrast the mitotic process in plants and animals. We grasped the concepts of what the chromosomes look like, and what they look like in each step of the processes. Having read much about mitosis and meiosis, seeing these cells was the real application of describing and understanding the stages.

Effect of Carica papaya seed extract on the cell wall of A. flavus under transmission electron microscope: In this experiment, transmission electron microscope was applied to detect the effect of papaya seed extract in the conidia cell wall and mycelia of A. flavus at concentration 100 & 200 mg/ml compared with control (without papaw seed extract). A small portion of the fungal mat was fixed at room temperature in 2% (v/v) glutaraldehyde mixed with potassium in 2% (w/v) osmium tetraoxide buffered in 0.005 M sodium cacodylate at pH 6.5 for 40 min. After fixation, the material was washed overnight in the appropriate buffer, dehydrated at room temperature in acetone, and embedded overnight at 65°C in low viscosity epoxy resin (Spuur, 1969). At these conditions, the material was polymerized; ultrathin sections were cut by glass knives of an ULKD ultramicrotome.
