Module 2: Cell Structures and Functions  OBJECTIVES At the end of the lesson, the students are expected to: 1. distinguish between the different structural components of the plasma membranes; 2. compare the structure and function of microfilaments, intermediate filaments, and microtubules; 3. describe the function and composition of the cell wall;  OBJECTIVES 4. describe the composition and role of nucleus and ribosomes in genetic control of the cell; 5. distinguish how the compositions and roles of organelles in the endomembrane system differ from one another; and, 6. compare the composition and role of chloroplast and mitochondria in providing energy for the cell.  TABLE OF CONTENTS Major Parts Subcellular of the Organelles Cell 01 Major Parts of the Cell Membrane-bound Organelles Organelles that are surrounded by a membrane called phospholipid bilayer. Non-membrane-bound Organelles These organelles are not contained by a membrane. UNA IMAGEN VALE MÁS QUE MIL PALABRAS STRUCTURE STRUCTURE STRUCTURE STRUCTURE STRUCTURE  Selective permeability is an important property of the lipid bilayer, in which it only allows certain molecules to move into and out of the cell. ROLES OF MEMBRANE PROTEINS ROLES OF MEMBRANE PROTEINS This consists of a network of protein fibers that gives the cell its structural framework. In addition to providing a structural framework to the cell, the cytoskeleton also serves other functions such as movement of organelles, macromolecules, and chromosomes.  TYPES OF CYTOSKELETON Microtubules consist of helically arranged globular proteins called tubulin. It radiate from the centrosomes Form spindle fibers  TYPES OF CYTOSKELETON Microfilaments They consist of They help facilitate long fibers of cell and organelle movement. actin protein, making them the They can help thinnest change the shape of cytoskeleton. the cell.  TYPES OF CYTOSKELETON Intermediate Filaments Helps maintain cell shape Anchors the nucleus  CYTOPLASM This is where all different subcellular structures are suspended. It is composed of the cytosol, a semifluid solution that consists of water and inorganic and organic molecules. CELL WALL CELL WALL CELL WALL  CHECKPOINT! 1. Give one major part of the cell and give its function. 2. Differentiate hydrophobic and hydrophilic. 3. Differentiate permeable and impermeable. 4. Give one type of cytoskeleton and give its function. 5.
