Study Notes
Bacteria
- Exist in diverse shapes, sizes, and functions, and can be found in almost every environment on Earth, including extreme conditions.
- Play crucial roles in ecosystems, including decomposing organic matter, nitrogen fixation, and symbiotic relationships with plants and animals.
- Some bacteria are harmful to humans, causing diseases such as tuberculosis, cholera, and pneumonia.
Fungi
- Are eukaryotic organisms, distinct from plants, animals, and bacteria, characterized by their ability to digest organic matter, produce enzymes, and form complex structures like mycelia and fruiting bodies.
- Can be found in almost every habitat, including soil, water, and air.
- Play essential roles in nutrient cycling, decomposition, and as symbionts with plants.
- Some fungi are harmful to humans, causing diseases like athlete's foot and yeast infections.
Viruses
- Are the smallest known infectious agents, consisting of a piece of genetic material (DNA or RNA) surrounded by a protein coat.
- Cannot replicate on their own and rely on host cells to reproduce.
- Infect all types of living organisms, including bacteria, archaea, plants, and animals.
- Can cause diseases ranging from the common cold to more severe illnesses like HIV/AIDS and Ebola.
- The diversity of viruses is vast, with new ones being discovered regularly.
