Cell Cycle & Mitosis
INTRODUCTION The purpose of this lab is to have a better understanding of cellular reproduction. When complete you will be able to identify animal and plant cells in the different mitotic stages.
METHODS & MATERIALS • Part I: Mitotic Stages. Recognizing the principle stages of mitosis in representative cells using an onion root tip, compound light microscope, and pre-prepared slides. • Part II: Estimating the duration of the respective stages of mitosis in an onion root tip.
Interphase Stages of the cycle during which growth and DNA synthesis occur when the nucleus is not actively dividing. Plant Cell
Prophase Chromosomes condense; nuclear membrane prepares for division. Animal Cell Plant Cell
Metaphase Chromosomes line-up independently in the center. Animal Cell Plant Cell
Anaphase Chromosomes separate and move towards the poles. Animal Cell Plant Cell
Telophase Daughter cells have 1 chromosome from each homologous pair. The animal cell begins to form a cleavage furrow while plant cells construct a new cell wall to divide the new daughter cells . Plant Cell Animal Cell
Cytokinesis Division of cytoplasm after Mitosis . This step only occurs in animal cells. Animal Cell
