Cell structure

• Organelles


  Basic cell parts that perform the physiological activities of the cell.
• Cell Envelope


  Covers and protects the cell, gives shape to the cell
• Cytoplasm


  Living substance of the cell. 70% cytosol
• Endoplasmic Reticulum


  Circulatory system of the cell.
• Rough ER


  Lined with ribosomes, for protein synthesis and transport
• Smooth ER


  No ribosomes, transport other materials other than protein
• Ribosomes


  Site for protein synthesis
• Mitochondria


  Manufactures energy in the form of ATP
• Cristae


  Infoldings in the Mitochondria
• Golgi Apparatus


  Processing and packaging plant and secretory vesicle
• Cisternae


  Fused flattened sacs or folds, also called dictyosome
• Centrioles


  Organizing centers for microtubules
• Lysosome


  tiny sac produced by golgi body.
• Lysozyme


  The digestive enzyme of the lysosome
• Peroxisome


  Contains enzymes that oxidizes fatty acids and amino acids
• Hydrogen Peroxide


  Byproduct of peroxisome
• Vacuole


  Membrane bound fluid sacs. Stores large amount of various materials like organic and inorganic molecules
• Cytoskeleton


  Interlinking filaments or tubules
• Microfilaments


  Made of actin, for cell movement and cytokinesis
• Microtubules


  Rigid hollow tubes made up of tubulin, maintains the cell shape. Forms the centrioles (spindle fibers)
• intermediate Filaments


  Provide strength and support
• Chloroplasts


  Site of photosynthesis
• Thylakoids


  Flattened membranous sacs containing chlorophyll
• Grana


  Pile of thylakoids
• Stroma 


  Spaces in the grana
• Flagella


  Long and thread like for cell movement
• Nucleus


  Brain of the cell.
• Nuclear Envelope


  Double membrane with many pores, controls the movement of material in and out of the nucleus
• Nucleolus


  Spherical body in the nucleus for the synthesis of protein
• Chromosomes


  Houses the genes
