                                   Cell
 There are two types of cell.One is Animal Cell & 2nd is Plant Cell
You can see in the picture the diagram of Animal &  Plant cell
                      Now the ORGANELLES of Cells
1. ENDOPLASMIC RETICULUM (ER)



















2.GOLGI APPARATUS
   

  1. The Golgi apparatus or Golgi complex is found in most cells. It is another packaging organelle like the endoplasmic reticulum (ER). It was named after Camillo Golgi, an Italian biologist.
  2. 3.LYSOSOMES

    1. An organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
      1. Lysosomes are cellular organelles that contain acid hydrolase enzymes that break down waste materials and cellular debris. They can be described as the stomach of the cell. Lysosomes digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria.

      2. 4.MITOCHONDRIA

        1. An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner part being folded inwards to form layers (cristae).
          1. Mitochondria are a part of eukaryotic cells. The main job ofmitochondria is to perform cellular respiration. This means it takes in nutrients from the cell, breaks it down, and turns it into energy. This energy is then in turn used by the cell to carry out various functions.

      3. 5.PLASTIDS
        1. Plastids are major organelles found in the cells of plants and algae. Plastids are the site of manufacture and storage of important chemical compounds used by the cell. Plastids often contain pigments used in photosynthesis, and the types of pigments present can change or determine the cell's color.
        2. Two more types of cell
        3. 1.Prokaryotic Cells
        4. 2.Eukaryotic Cells
