Curriculum
Module 1: Foundations of Cell Biology
This module lays the groundwork for understanding cells, starting with an introduction to cell theory and its historical development. You will explore the key differences between prokaryotic and eukaryotic cells, learn to identify various cell structures, and examine the functions of shared cellular components. Lectures cover the discovery of cells, the evolution of cell theory, visualizing cells, and a detailed overview of the structures common to all cells and the distinctions between prokaryotic and eukaryotic cells, followed by an in-depth look at various cell organelles and their specific functions within the cell.
Module 2: Cell Membrane & Transport
This module delves into the dynamic nature of the plasma membrane, its selective permeability, and the mechanisms that govern the movement of substances across it. You'll explore the fluid mosaic model, the roles of membrane proteins and phospholipid bilayers, and the different types of cellular transport, including passive transport (diffusion, osmosis, facilitated diffusion) and active transport (exocytosis, endocytosis). Lectures explain membrane function, selective permeability, the intricacies of the fluid mosaic model, membrane component details, and a comprehensive analysis of diverse transport mechanisms crucial for cellular processes.
Module 3: Cellular Organelles: Structure & Function
This module provides a detailed exploration of major organelles and their roles in cellular functions. Starting with the nucleus and genetic material (DNA and RNA), you will investigate the structure and function of mitochondria, chloroplasts, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes. Lectures analyze the nucleus, genetic material, nucleotides, DNA structure, RNA types, mitochondrial function, chloroplast function and structure, endoplasmic reticulum function, Golgi apparatus function, lysosome properties and functions, and a detailed examination of peroxisomes and their functions within the cell.
Module 4: Cytoskeleton & Cell Architecture
This module examines the cytoskeleton – a dynamic network of protein filaments that provides structural support and facilitates intracellular transport. Lectures explore the structure and function of microtubules, microfilaments, and intermediate filaments, and their contribution to cell shape, movement, and intracellular transport. Lectures further explain the role of the cytoskeleton, its filament types, and its functions in structural support and intracellular transport. The role of motor molecules, cilia, flagella are also examined in detail.
Module 5: Cell Junctions & Extracellular Matrix
This module focuses on how cells interact with each other and their surroundings. You will learn about cell walls in plants, the extracellular matrix (ECM) in animals, and various types of cell junctions (tight junctions, desmosomes, gap junctions, plasmodesmata). Lectures delve into plant cell walls, their layers and composition, ECM structure and function, types of cell junctions, plasmodesmata in plants and their function, cell adhesion molecules (CAMs) and their diverse types, and a detailed exploration of the ECM and its constituents: collagens, fibronectin, proteoglycans, and hyaluronan.
