GENERAL BIOLOGY LAB EXPERIMENT 7: MITOSIS AND MEIOSIS . ... pulling through onion root tip cell’s poles .In 1842, C. Nägeli first saw chromosomes and in 1888 W. Waldeyer named them. Walther Flemming studied and named the process of cell division as mitosis. Cell division occurs rapidly in growing root tips of sprouting seeds or bulbs. The most commonly used root tips in labs to study mitosis are onion, wheat, lentil, barley and alfalfa.

(Mitosis) Introduction: In this lab, you will examine the dividing root-tip cells of an onion. You will examine the. specimen to identify the various phases of the cell cycle, to see which …Describe Prophase. This is the first step of mitosis. The nucleus is still present. (It will go away later.) The chromosomes are condensing. (thickening and visible) Describe Metaphase. The chromosomes line up in the middle of the cell. The nucleus has been disassembled, and is no longer there, and is waiting. (M for Middle.)

Terms in this set (15) DNA is all spread out as chromatin and nuclear membrane is visible. DNA scrunches up and chromosomes are first visible. Chromosomes line up in the middle of the cell. DNA is copied and cell prepares to divide. Chromatid arms separate and move to opposite ends of the cell. Nuclear membrane and nucleolus disappear.The Cell Cycle The cell cycle is a series of stages that occurs when a new cells makes the division from the parent cell to two daughter cells. This is a stage in cellular reproduction. The cell cycle consists of three phases, interphase, mitosis, and cytokinesis. During Interphase, a cell will continue to perform its functions as usual.

During telophase, the chromosomes condense and the cell prepares for cytokinesis, in which the cell splits into two identical daughter cells. Interphase and the stages of mitosis are seen in Figure 1 below.
