Pathogens and Diseases (P2)
Virus
Description (unique structural features)
The viruses can have DNA or RNA and a protein coat called capsid that protect the nucleic acid which is formed of many small protein particles called capsomeres. Envelope is situated around the capsid which is composed of a membrane named bilipid layer and glycoproteins.
Some examples of diseases caused by viruses are influenza, Ebola virus, chicken pox, etc.
Describe how the disease is transmitted
This disease is easy to take because the flu viruses transportable through the air. Influenza virus can be transmitted to humans in 3 ways. Firstly by direct contact with people that are infected, secondly by contact with contaminated objects and last one by inhalation of virus.

Bacteria
Description (unique structural features)
In exterior of bacteria is a cell wall that give to it the shape. Next to this is plasma membrane that surrounds the living cells. Inside the membrane is filled with cytoplasm. Attached to cytoplasm are ribosomes, nucleoid and plasmids.
Some examples of diseases caused by bacteria are cholera disease, tuberculosis, lyme disease, etc.
Describe how the disease is transmitted
The cholera bacteria can be transmitted to humans through food and water. The contamination of them can cause infections and goes to diseases.

Fungi
Description (unique structural features)
There are organelles that help the cell to function, such as mitochondria, endoplasmic reticulum, lysosome, centrioles, Golgi apparatus, and ribosomes. As bacteria, fungi have a plasma membrane and a cell wall. Nucleus is situated inside of the cell which is a genetic material.
Some examples of diseases caused by fungi are athlete’s foot disease, fungal meningitis, fungemia, etc.
Describe how the disease is transmitted
Athlete’s foot is a contagious disease. It can be transmitted through direct contact. The infections can be taken from skin particles left it on towel, floors or shoes.
