Organelle

• Organelle


  Is a membrane-bound organelle structure within its cell. Its membrane is similar with the cell's lipid membrane that holds all the cells components. Each organelle in the cells perform a specific task wherein the combination of these task expresses the overall function of the cell.
• Prokaryotic Cell

  • Do not have structures surrounded by membranes
  • Few internal structures
  • One-celled organisms, Bacteria
• Eukaryotic


  Contain organelles surrounded by membranes

  Most living organisms
• Animal Cell


  The eukaryotes constitute the domain of life Eukarya, organisms whose cells have a membrane-bound nucleus. All animals, plants, fungi, and many un-cellular organisms are eukaryotes.

  
• Cell Membrane


  The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting
• Cell Wall

  • Most commonly found in plant cells and bacteria
  • Supports and protect the cells
• Nucleus

  • Directs cell activities
  • Separated from cytoplasm by nuclear membrane
  • Contains genetic material - DNA
• Nuclear Membrane

  • Surrounds nucleus
  • Openings allow material to enter and leave nucleus
• Nucleolus

  • Inside nucleus
  • Contains RNA to build proteins
• Mitochondria


  Known as the “powerhouses of the cell,” mitochondria produce the energy necessary for the cell's survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes
• Endoplasmic Reticulum

  • Moves materials around in cell
  • Smooth type: lacks ribosomes
  • Rough type: ribosomes embedded in surface
• Golgi Body


  Move materials within the cell

  Move materials out of the cell
• Lysosome

  • Transports undigested material to cell membrane for removal
  • they are also known as the “suicide bags” of the cell.
• Chloroplast

  • Usually found in plant cells
  • Contains green chlorophyll
  • Where photosynthesis takes place
• Chloroplast


  Chloroplast is the organelle responsible for Photosynthesis, a process where plants convert the energy from the sun into glucose.

  They contain chlorophyll and other pigments slacked in their thylakoid membranes.
• Cytoskeleton

  • Skeleton of the cell.
  • Maintains the cell’s shape and assist with transport.
• Cytoskeleton


  This organelle is responsible for giving the cell its shape and assisting the transfer of materials in and out of the cell

  It is composed of three main components:

  Microfilaments

  Filaments

  Microtubules
• Cytoplasm


  Cytoplasm is the gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules. Some intracellular organelles, such the nucleus and mitochondria, are enclosed by membranes that separate them from the cytoplasm.
• Ribosomes


  A ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell. The ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins.
• Vacuoles


  Vacuoles are membrane-bound organelles that can be found in both animals and plants. In a way, they're specialized lysosomes. That is to say that their function is really to handle waste products, and by handle, mean take in waste products and also get rid of waste products
