**Lab 2. Cellular Anatomy and Cell Division** **Introduction:** Most of the material for this lab should be review for you, but despite having previously studied this material, students often struggle with the concepts and skills presented here. Don\'t worry, that\'s normal! You will also be introduced to models and illustrations depicting cellular anatomy and cell division, but you will need to be able to do much more than merely recognize the structures. To prepare for this lab, read Chapter 3 in your text (we\'ll come back to Chapter 2 later), paying special attention to cell division and protein synthesis. **During this lab, you will review the following topics:** *Generalized Animal Cell Model (see also Color Plate 6 and your text):* Identify the following structures and understand their functions: Plasma (cell) membrane, free ribosomes, smooth and rough endoplasmic reticulum, Golgi apparatus/complex/body, lysosome, centrosome, nucleus (with nuclear envelope and pores, chromatin (includes DNA), and nucleolus), cytoplasm (contains cytosol and organelles), mitochondria, flagella, microvilli, cilia, cytoskeleton. C:\\Users\\ah006\\Downloads\\IMG\_0050.jpg *The cell cycle:* Be able to recognize phases of the cell cycle using the models, the illustrations in the coloring book and text book, and understand the events of the following phases of the cell cycle: Interphase (G1, S, and G2); mitosis (prophase, metaphase anaphase and telophase); cytokinesis. *Mitosis vs. Meiosis:* We will study meiosis again when we study gametogenesis, the formation of gametes (eggs and sperm). At this point, you need to understand the differences between meiosis and mitosis, and why those differences exist. Please refer to the textbook and lecture materials.

Cytokinesis (right). Cytokinesis is not part of mitosis per se, but usually occurs following mitosis.
