Garlic Root Tip Lab Report
Observation of Mitosis in Garlic Root Tips:
Abstract:
This practical examined garlic root tip cells for the observation of the five stages of mitosis.Mitotic division consists of five significant stages which were identified and recorded. The results revealed that the garlic root tip cells are in the interphase stage of the cell division cycle for majority of the time.
Introduction:
This lab report outlines an experiment on the observation of mitosis in the cells of garlic root tips. Mitosis simply put is the division of a nucleus producing two daughter cells with the same number of chromosomes as the parent cell. Miotic cell division consists of five stages: Interphase, Prophase, Metaphase, Anaphase and Telophase. The purpose of this experimet was to identify and observe cells within each stage of mitosis using garlic root tip cells. 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

Telophase:the chormatids are now called chormosomes. The nuclear envelope reforms arounds the two sets of chromosomes to form two new nuclei and in each nucleus the nucleolus reforms. The spindle fibres disappear and the chromosomes become uncoiled, elongated and are no longer visible.
Unknown Culture Lab Report
1054 Words | 5 PagesIdentification of bacteria within Unknown Culture #21 In this experiment, an unknown culture of two different types of bacteria was assigned to each person, a number of tests were performed to isolate and identify these bacterial cells. Based on knowledge from the previous experiments completed in lab, a basic understanding of each type of bacteria was used to create a flow chart that would aid the process of identifying the unknown bacteria within the culture. A gram stain that is performed initially will narrow down the types of tests certain bacteria will and will not respond to. In addition to the gram stain, some of the tests that were used include, a catalase test, an Eosin methylene blue (EMB) agar test, a bile esculin test, and a 6.5% sodium chloride (NaCl) test.

549 Words | 3 Pagesthree phases G1, where the cells grows up to double it’s original size, S phase, where the dan is replicated , and G2 ,where the cells finishes it growing and prepares to go into prophase. Prophase is where the cell’s nuclear membrane dissolves. Chromatin tightly coils and condenses into chromosomes. Spindle fiber begins to appear and then the cell goes on to metaphase. During metaphase, the cell’s spindle fibers attach to the chromosomes and the chromosome aline in the middle of the cell.

Materials and Methods: Tests: Lactose fermentation: Fermentation makes energy available for use by microorganisms by anaerobic breakdown of carbohydrates. The product can either be an acid or gas. When it is positive, the broth will turn from red to yellow and if gas is present a bubble is formed.

To fix this issue, three scientists had to determine the contaminants that were present in the samples. One sample was from the school sink and the second sample was from an unknown source. The scientists conducted many tests to figure out what pollutants were present in the water.

Throughout the two week observation period, the “tail” segment did not grow at all and showed very few signs of vitality, but by the second week, a new head had started to form on the “tail” segment. Comparing the results of the experiment to my initial hypothesis, I was incorrect, the “head” segment grew more than the “tail” segment, although not by much. There could have been some error with the measurements because the tail segment did not really move at all and tended to shrink up

In telophase II, the sister chromatids reach their respective poles. Cytokinesis takes place, and the nuclear envelope becomes visible, resulting in four haploid

Gametophyte is small in size and can photosynthesize. In order for the fertilization to take place, enough water should be available so that the sperm may swim to archegonia and fertilize the eggs.

An example of a organism who has multicellular cells are plants, animals, and humans. The main reason of why scientists have a hard time finding a good set of existing organisms to compare. Is neither the first set of organisms which is being compared is dying as fast as the second specimen is being examined or they just can’t find the right species.

Translocation is another method were segments of the chromosomes rearrange itself which moves either to another part of the chromosome or to the same chromosome. The balanced translocation is when DNA is equally provided between both chromosomes nothing is added or taken away.

Ans: This lab has given me methods to extrct DNA from both plant cells and animal cells. The main steps that are followed in both methods made me understand the reasons behind them. In order to extract DNA we need break the barriers(cell wall and cellmembrane), remove water, protiens and other unwanted material, make sure that the chemical we used should not damage DNA that we need and add flouroscent material to visualize the DNA.

Gene mapping is the relationship between the frequency of second division segregation and distance (map units) between the genes involved. Recombinant ascospores have chromosomes that were altered by the crossover in metaphase of meiosis. They phenotypically do not represent the parental chromosomes. When spores resemble the parental chromosomes, they are called non-recombinants and they result from being unaffected by the crossover.
