In this organelle, it possesses a photosynthetic pigment known as chlorophyll, which uses light as a source of energy and converts simple molecules into complex molecules. For the photosynthesis, the chloroplasts are the main sites and in this process the CO2 and H2O that convert glucose molecules in the presence of light energy. Each chloroplast is green in color, double layer membrane organelle. This organelle posses…

Structure and Function of Cytoskeleton and Its Role in Motility

  • A cytoskeleton is the cellular skeleton contained within a cell՚s cytoplasm which is made out of protein. In 1903, Nikolai proposed that the shape of cells was determined by a network of tubules which is termed as the cytoskeleton. This cytoskeleton is present in both prokaryotic and eukaryotic cells.
  • The skeletal system of the eukaryotic cell supports in providing mechanical support to the soft tissues for their functional movements and such system is known as cytoskeleton. It helps the eukaryotic cell adapt to any shape. It is also known as cytomusculature due to the diversified flexible functions it performs. This cytoskel…
