  • Life In A Cell

    1. 2. Content <ul><li>Function of a cell </li></ul><ul><li>Types of cell </li></ul><ul><li>Cell functions </li></ul><ul><li>Cell division </li></ul><ul><li>Structure of cells </li></ul><ul><li>Manufacturing and transport of cells </li></ul><ul><li>Amount of cells and its effect </li></ul><ul><li>Conclusion </li></ul>
    2. 3. Types of cell <ul><li>Prokaryotic cells </li></ul><ul><li>have small loops of DNA called plasmids which can be transferred to other cells. </li></ul><ul><li>lack a nuclear membrane and a cell nucleus. </li></ul><ul><li>usually a circular molecule. </li></ul><ul><li>Eukaryotic cells </li></ul><ul><li>larger and more complex. </li></ul><ul><li>true nucleus containing the DNA. </li></ul><ul><li>one or more linear molecules. </li></ul><ul><li>membrane-bound compartments in which specific metabolic activities take place. </li></ul>
    3. 4. Cell functions <ul><li>Cell growth and metabolism </li></ul><ul><li>Cell metabolism is the process by which individual cells process nutrient molecules . </li></ul><ul><li>Creation of new cells </li></ul><ul><li>Cell division involves a single cell (called a mother cell ) dividing into two daughter cells. </li></ul><ul><li>Protein synthesis </li></ul><ul><li>essential for the modulation and maintenance of cellular activities </li></ul><ul><li>involves the formation of new protein molecules from amino acid building blocks based on information encoded in DNA. </li></ul>
    4. 5. Cell division
    5. 7. Function of cell <ul><li>Communication </li></ul><ul><li>Raw materials </li></ul><ul><li>Exchange of materials </li></ul><ul><li>Energy </li></ul><ul><li>Reproduce </li></ul>
    6. 8. Cell structure <ul><li>Mitochondrion(Energy generator) </li></ul><ul><li>Rough endoplasmic reticulum (Transporter) </li></ul><ul><li>Exocytosis (Secrete protein) </li></ul><ul><li>Cytosol ( Receptor) </li></ul><ul><li>Microtubule ( Mitosis ) </li></ul><ul><li>Centriole (Mitosis) </li></ul><ul><li>Vacuole ( Exporting waste products) </li></ul>
    7. 9. Manufacturing and transport of cells <ul><li>Why we need cells? </li></ul><ul><li>building block of life </li></ul><ul><li>need new cells to replace the dead cells. </li></ul><ul><li>Common materials made by cells </li></ul><ul><li>tissue, bacteria, hormones and viruses. </li></ul>
    8. 10. Conclusion <ul><li>Living things reproduce. </li></ul><ul><li>The cells need raw materials. </li></ul><ul><li>There are different components inside a cell. </li></ul><ul><li>Mitochondria is present in ATP where energy is produced. </li></ul><ul><li>There are two types of cell division. </li></ul><ul><li>In the cell, it has many processers e.g. it receives raw materials. </li></ul>
