- How does plant cytokinesis differ from animal cytokinesis? Opposing forces distribute the cell contents to opposite poles of the cell. a cell plate forms from which the new cell wall will be formed. A cleavage furrow, made possible by contractile rings, form during cytokinesis. O Kinetochore microtubules pull the cell apart.Discuss the special features of cytokinesis in a higher plant cell.VISUAL SKILLS The light micrograph shows dividing cells nearthe tip of an onion root. Identify a cell in each of the followingstages: prophase, prometaphase, metaphase, anaphase, andtelophase. Describe the major events occurring at each stage.
- Which of the following are stages in the cytokinesis of animal cells? Select all that apply. After telophase, the contractile ring constricts the plasma membrane and forms a cleavage furrow. A contractile ring of microfilaments and motor proteins forms under the plasma membrane during anaphase. The cell plate expands along the plane of division, and when the plate fuses with the plasma membrane, the cytoplasm is partitioned into two new cells. The contractile ring reaches its smallest diameter, and the spindle microtubules are cut as vesicles form the new membranes that separate the two new cells.Cytokinesis takes place after telophase. True False Both aerobic and anaerobic respiration produce ATP True False Which of the following events does not take place during prophase? Movement of chromosome to the mid zone of the nucleus. Construction of spindle fibre. Chromosomes are separated as chromatids. O The chromosomes condense into compact structures.TELOPHASE This stage shows the end of Telophase AFTER cytokinesis has occurred • Nuclear membrane reformed in each cell • Nucleolus reformed in each cell • Centrioles present in cells at one end Two new daughter cells with same # of chromosomes: 46 single stranded chromosomes in each nucleus Daughter Cell Diploid cell 2n = Daughter cell Diploid cell 2n =
