  • The diagram is of a plant cell and its organelles.
  • The nucleus houses the genetic material and controls all life processes.
  • 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.

Suppose that a person takes a fall while hiking and develops tetanus when the pathogen enters through an open wound in their arm
qaws [65]

The tetanus infection is considered to be a Droplet infection.

<h3>What is Tetanus?</h3>

Tetanus is a neurological disease which is characterized by the occurrence of spasms in the muscle.

Tetanus can be caused if initial care does not take place after the wound occurs and therefore, it is very important to immediately take care of the wound.

To treat the wound tetanus immunoglobulin and tetanus toxoids are given to the person, however, it is necessary to give the two injections using different syringes and at different sites, because the immunoglobulin can cause neutralization fo the toxoid.

Thus, this could be the answer.
