Cell Division

I believe that our observations atomic number 18 repressentative of electric boothular phone constituent taking place in the oinon motif tip. Firstly, this is because our numbers of the number of cubicles in all(prenominal) phase of mitosis be same to the continue of the groups, so we can arrogate our results are most likely correct. We can in like manner assume our calculations are right because we sport it off that Interphase is the most active phase in the solve of jail cell divison, which would agree with our calculations since we assume that approxiamtly 93% of cells are going though Interphase.The phases of mitosis are much shorter then that of Interphase, and the cell spends less time in these phases. This agrees with our calculations because they give-up the ghost around 2-10%, conculding the fact that it is right to infere that a smaller amount of cells would be in the phases of mitosis. 5. Plants use a similar process with a few deviances than in the gra cious beings process. A plant cell creates a mitotic spindle and has a centrosome, but it does non have a centrioles, as in human chromosomes. The other major difference in plants is the way in which cytokinesis occurs.In human cells, the plasma membrane invaginates along the equator of the cell, creating a cleavage furrow that will conk out the cytoplasm in two lady friend cells. Plant cells have rigid cell breakwaters that delay this. Instead, they use two antithetic approaches for cytokinesis. The plasma membrane and cell groin grow inward together, eventually separating the provoke cell into two. Then the cell wall(which human cells do not contain) will break out the two young lady cells, and the cell wall starts growing in the middle of the cell between the two nuclei. This is known as the cell plate.It continues growing until its edges r distributively(prenominal) the cells out surface, separating the parent cell into two young lady cells. 6. Not all cells in the meristematic neighborhood of the onion appear to have a pith. This is because The earliest cells, and all prokaryote cells, dont have a nucleus. Inside these simple cells, the desoxyribonucleic acid molecules just float around in the cytoplasm. When the cells have devoloped, most likely during telophase,the nucleus will appear. 7. The result of if the chromosomes of the two daughter cells remained on one side of the cell plate could be non-disjunction, where a chromosome whitethorn fail to separate during anaphase.One daughter cell will receive both babe chromosomes and the other will receive none. This results in the former cell having three chromosomes containing the aforementioned(prenominal) genes (two sisters and a homologue), and will develop into a condition called trisomy, and the latter cell which would solely have one chromosome (the homologous chromosome), would be a condition known as monosomy. These cells are considered aneuploid, a condition practically associated with cancer. 8. A class result is purify in the measure of the time for each miotic phase because we can contrast each number of time that each group gets.If the numbers are similar we can infere that it is more probable to be the right answer, and can exclude all numbers that are an abnormal greater difference then the rest. By study all the calculations and observations of the class, we can justify the observations that are similar to those of the rest of the class. 9. Biocide 2-4D would harm and prevent the action of the substances within the meristematic cells of the plants. It will excessively cause major issues in devolve on cells because the chromosomes during metaphase 1 will not supercede proper genes with each other.
