  • A fixed joint is like the sutures of the skull. The joints hardly move.
  • The hinge joint is those that have 90 degrees freedom of movement such as the elbow joint.
  • Gliding joint occurs where one bone glides over the other's flat or nearly flat articular surfaces. Examples are those of the ankles.
  • The ball-and-socket joint allows for 180-degree freedom of movement. An example is the joint at the hip bone.

  • A plant cell contains one large vacuole in the center that stores water and nutrients.
  • Chloroplast is the site for photosynthesis. It captures light and utilizes it and carbondioxide to produce glucose.
  • Mitochondria are called the power house of the cell. Through a process called cellular respiration, they break down the glucose produced in photosynthesis into energy compounds such as ATP as well as oxygen and water.
  • The endoplasmic reticulum is the site for protein sysnthesis. It contains two parts: the rough endoplasmic reticulum (RER) which contains ribosomes that synthesize proteins and the smooth endoplasmic reticulum (SER) which packages the proteins into transport vesicles.
  • The nucleus contains the nucleolus that is the site for ribosome assembly.
  • The cell membrane is a semi-permeable membrane that covers the cell and controls cellular transport.
  • The cell wall is a hard, outer covering that protects the cell and maintains its structure and shape.
