1. Why do you think the roots of plants are good for studying Mitosis? In my biased opinion, I believe that the roots are suitable for studying mitosis because plants always undergo mitosis. 2. Why does the root tip of the onion need to be stained? The root tips of the onion need to be stain because they provide more visibility when looking under a microscope. 3. How many phases are in the Cell Cycle? There are five stages of the cell cycle which would be Interface, Prophase, Metaphase,…

Briefly identify and describe the stages of interphase and mitosis associated with Figure 4.4 of your laboratory textbook. During the four phases of interphase synthesis known as chromatin condensation and cell preparatory phase of division. The following phases take place in this process: gap 1 phase (G1) (cells grow/synthesize proteins required for mitosis activating the cell’s metabolism to break down carbohydrates/lipids transforming food into energy, this phase chromosomes consist of only…

Cell division is essential in the life cycles of all cells. It allows living organisms to reproduce and therefore not die out. There are two major steps to cell division: nuclear division and cytokinesis. Within nuclear division are two different types: mitosis and meiosis. Mitosis is a form of asexual reproduction in which one diploid parent cell is divided into two identical diploid cells. On the other hand, meiosis is an example of sexual reproduction, in which two diploid parent cells both…

Meiosis is used when the whole organism’s time comes to reproduce. This type of cell division has two divisions, known as Meiosis I and Meiosis II. During Meiosis I, the spindle fibers attach to the kinetochore at the centromeres (OpenStax, 2013). In meiosis, the cell membrane dissolves and the chromosomes separate, which produces four daughter cells. Within this separation, the chromosomes transfer genetic material to each…

such a platter is rotation the angular acceleration could be pointing toward or away the observer, in this lab we are going to be investigating the rotational motion for which a dish undergoes. For this experiment we are going to be testing three spindles with different radius. According to the author, in this experiment we are going to be applying Newton’s second law which is Linear: Fy=T-mg=ma and Angular t=rT=Ia.( Cutnell) In this experiment the maximum mass we are going to be using…

into four stages. NREM sleep can be differentiated from rapid eye movement (REM) sleep due to its lack of muscle paralysis and bursts of eye movement typically observed in REM sleep3. Additionally, NREM sleep demonstrates characteristic waves and spindles captured on electroencephalogram (EEG) readings that differ significantly from REM sleep5. 2.1.1 Stage 1 NREM Sleep During periods of wakefulness, a frequency of greater than 13 Hz can be read on an EEG output, which is frequently denoted as a…

condenses into chromosomes, and the nuclear envelope breaks down. The centrioles near the nucleus begin to separate and move to opposite poles of the cell. Then during metaphase spindle fibers attach to the centromere of each pair of…

phase, G2 phase, & M phase. The G1 phase is where the cell is assigned to enter the process for chromosome duplication. DNA replication occurs in the S phase. The third phase, G2 phase, the process of mitosis triggering the alignment of the mitotic spindles. Mitosis and cytokinesis are two important functions that occur throughout the M phase. The three stages…

cause harm to an infant if given during pregnancy. The spindles in mitosis are very important because they help to split the newly copied DNA such that a copy goes to each of the two new cells during cell division. The drug vincristine disrupts the formation of the spindles and therefore interrupt cell division. The drugs that harm the process of mitosis are represented by microtubule binding drugs that inhibit the function of the mitotic spindle in order to halt the cell cycle in mitosis and…

In cell theory, it is known that all cells arise from pre-existing living cells, through cell division. In cell division, this involves the supplying of identical genetic material from the parent cell, DNA and protein, to two daughter cells. It results in the daughter cells having the same number of chromosomes as the parent cell. We need cell division as it is used in reproduction of new species, growth and repair of damaged cells and tissues, and to reduce the cell size. Larger cells are…
