What is Life? This perennial question the answer to which has somehow eluded the most brilliant minds. For while scientists have identified many years ago the right mix of the atoms and molecules that constitute cellular material‚ they have not succeeded in ‘switching it on’ to make it alive‚ or ‘breathing life’ into it (Rabago et.al‚2006) In this module you will: a. Explain the concepts of the cell theory b. Identify the parts of a cell c. Describe the function of each cell part d. Differentiate

Premium Cell Organelle
Cytoplasm: All organelles inside the cell are suspended in the cytoplasm. The cytoplasm is mostly water which allows the organelle to move around. It fills the interior of the cell. Vacuole: Are storage bubbles they store food‚ nutrients and waste. They also maintain internal fluid pressure within the cell. Lysosomes: Contain digestive enzymes and break down nutrients‚ they digest excess or worn-out organelles‚ food particles‚ and engulfed viruses or bacteria. Rough ER: Are very important in the

Premium Cell DNA Protein
antigen-presenting cell. During phagocytosis‚ macrophages are activated to destroy (consume) the bacteria devouring many times their own body mass in bacteria‚ essentially killing them with the macrophage’s acid-filled vacuoles. The ingested pathogen becomes trapped in a phagosome‚ which fuses with lysosome; from this enzymes and toxic peroxides digest and kill the pathogen. However‚ some advance pathogens such as Mycobacterium Tuberculosis have become resistant to the immune-defence mechanisms of the macrophage
