We then obsevered the two slides for number of cells as well as for food vacuoles inside a cell using a microscope at times of 0,5,10,20, and 30 minutes. Results The following graphs show the results of this experiment. The tetrahymena sample that was introduced to concentrated tobacco had a lower cell/vacuole ratio than the tetrahymena sample that was not exposed to
This is the same number of intercellular moves reported by Yin and Yasuda (2002) [14]. A total of 30 intercellular moves are resulted by Gupta (1993) [12]. The best routes of proposed approach is P1(1), P2(1), P3(2), P4(2), P5(1), P6(1) and P7(1). Table 6 shows the solutions of cell formation by different approach.
elegans with two petri dishes. One Petri dish contains homozygous hermaphrodites and homozygous dpy-3 -/-, his-8 -/- C. elegans. The second dish contains dpy-3 +/, his-8 -/- male. We had another dish with only E. coli which we used to transfer C. elegans from one Petri dish to another. The materials that we used when conducting this experiment are: dissecting microscope, 3 petri dishes, C. elegans (male, female, and hermaphrodites), worm pick tool, agar, Bunsen burner, Parafilm, incubator, and flint spark lighter.
The hypothesis for this experiment was that transformed bacterial cells would grow on ampicillin plates and glow green when exposed to UV light. The rationale for this hypothesis was because the plasmid would code for ampicillin resistance and a green fluorescent protein, we would have the outcome explained in the hypothesis. 4. Our predictions were that for the standard protocol plates with agar and ampicillin, there would be growth and the colonies would glow under UV light. On the modified protocol on plates with agar and ampicillin where we changed the time of the heat shock, we expected less growth but the colonies would still glow.
Transformation was successful in the plates where the bacteria consumed the pGLO plasmid. In the first plate that the bacterium was plated on it included the LB broth and of ampicillin antibiotic (amp), 2 colonies were present. The second plate of bacteria was grown with the presence of LB broth, ampicillin, arabinose sugar (ara), and 22 colonies were observed. But a green fluorescent glow of the colonies was only present in plate 2. Plates 3 and 4 were the control plates.
The structure of the cell was very visible when using the anti-tubulin. When observing the anti-actin the microfilaments were visible. The actin filaments were much thinner than those of the microtubules. The actin filaments were best observed in the periphery of the cell compared to those of the tubulin, which are spread throughout the cell because they help stabilize the cell. The TRITC dyed cells depict better the whole structure of the cell, the nucleus is more visible than those that are dyed with FITC.
Long ago, there lived a slime mold named Stemonitis Fusca who lived in Scotland. Stemonitis was new to his home in the Caledonian Forest. He found a nice, cozy spot in a deciduous tree’s trunk. Slime molds usually live on forest floors or tree trunks just like Stemonitis. Anyways, when our furry slime mold friend moved into his new tree trunk home he was in his haploid state of the slime mold cycle.
Methods Four experiments were conducted to determine how fast snails would move in 1 minute at different temperatures based on their population size. In this experiment each member of the group (4 members) received 3 groups of snails. The groups consisted of 1 snail, 5
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
At this point the two halfs seperate marking the end of cytokinesis and the end of cell replicaton. Cell plate structure formed during plant cell cytokinesis by Golgi vesicles, forming a temporary structure (phragmoplast) and fusing at the metaphase plate; ultimately leads to the formation of Cell walls that separate the two daughter cell cytokinesis division of the cytoplasm following mitosis that forms two daughter cells FtsZ tubulin-like protein component of the prokaryotic cytoskeleton that is important in prokaryotic cytokinesis (name origin: Filamenting temperature-sensitive mutant Z) Learning Journal Entries Reading Material
When you choose to ignore moisture that is building up in your home, it is not surprising to see mold. After all, mold is a microorganism that loves to take shelter in damp, humid, and dark places. Most of the time, you’d brush off the existence of mold on your wall, floor, or ceiling. But we, at Dreyer’s DKI, strongly suggest that you address mold issues with great concern. What Makes Black Mold Dangerous?
How are fungi related to mold. Molds are a group of fungi called, Hyphomycetes which are characterized with having, filamentous hyphae Filamentous hyphae means that they have long and visible chains of hyphae. When growth of hyphae happens, mold forms. They have a fuzzy appearance ,they appear mostly on food. .
In this practical agar jelly cubes will be used to represent a cell. AIM: To model diffusion in a practical form and investigate the effect of surface area to volume ratio. HYPOTHESIS: It is hypothesised the smaller the cube the quicker and bigger the rate of diffusion will be and with a larger cube there will be a smaller percentage of diffusion due to its bigger volume.
The cells are put together by a slime they secrete. This is because single cells could be deserted of to some area where else they can not survive. Cyanobacteria also lack flagella, making it
The process itself begins with vapor diffusion, a way to grow
