Explore the fascinating world of cells, the structural and functional units of life. Learn about their components, functions, and significance in the survival of living organisms.

This course covers: Definition, structure, and components of the cell Differences between unicellular and multicellular organisms Functions of cell organelles Transport mechanisms: diffusion, osmosis, and active transport Cell theory and its significance Practical applications and biological insights

By the end of this course, learners will: Understand the structure and functions of the cell. Differentiate between unicellular and multicellular organisms. Comprehend the significance of cell organelles. Gain insights into cellular transport and division.

Module 1: Introduction to the Cell Definition: The structural and functional unit of life Discovery of the cell by Robert Hooke Overview of cell theory (Schleiden, Schwann, and Virchow) Why the cell is considered the basic unit of life Module 2: Types of Organisms Unicellular Organisms: Characteristics and examples (e.g., bacteria, protozoa, amoeba) Importance and limitations of single-celled life Multicellular Organisms: Characteristics and examples (e.g., humans, plants, animals) Advantages of multicellularity (division of labor, specialization) Module 3: Cell Structure and Shape Components of a cell: Plasma membrane, cytoplasm, and nucleus Shape and size variations: Amoeba and white blood cells Nerve cells, muscle cells, and red blood cells Differences in plant and animal cells Module 4: Cell Organelles Functions and features of key organelles: Nucleus: The control center of the cell Mitochondria: The powerhouse of the cell Endoplasmic reticulum: Smooth and rough ER Golgi apparatus: Packaging and distribution Lysosomes: The digestive system of the cell Vacuoles: Storage units Chloroplasts: Photosynthesis in plants Prokaryotic vs. eukaryotic cells Module 5: Plasma Membrane Structure and composition Selectively permeable nature: Diffusion and osmosis Active and passive transport What happens when the plasma membrane ruptures? Module 6: Cell Theory Applications Relationship between cells, tissues, organs, and organ systems Division of labor in multicellular organisms The role of cells in growth and repair Module 7: Advanced Topics Cell division: Mitosis and meiosis The impact of solutions on plant cells: Hypertonic, hypotonic, and isotonic environments Special functions of cell components
