Characteristics of Bacteria
What is bacteria?
Microscopic prokaryotes
What is flagella?
Many bacteria have long whiplike structures.
What role do bacteria play in a cow's digestion?
Cow's get help digesting the cellulose in plants from the bacteria that live in their rumen-one of four stomach sections.
What are pathogens?
agents that cause disease.
What is a virus?
A strand of DNA and RNA surrounded by a layer of protein that can infect and replicate in the host cell.
What is the structure of bacteria?
Consists of cytoplasm and DNA surrounded by a cell membrane and a cell wall.
How does bacteria move?
Bacteria uses the flagella to move from surfaces to other surfaces.
What is decompositions?
What is the importance of antibiotics?
Medicines that stop the growth and reproduction of bacteria.
What are the 4 shapes of viruses?
Cylinder, Crystal, sphere, bacteriophage
What are the three basic shapes of bacteria?
Round or Sphere-shaped, rod shaped, spiral-shaped
What is fission?
What is nitrogen fixation?
Conversion of atmospheric into nitrogen compounds that are usable by living things.
How do bacteria develop resistance to antibiotics?
Over time bacteria will become more resistant and become more common. Which will cause bacteria to not respond to antibiotics.
Are viruses alive? Explain why or why not.
Viruses is not alive, because they do not have all the characteristics of a living organism.
How do bacteria obtain food?
Bacteria feed on dead organisms or organic waste. Bacteria makes its own food, uses light energy to make food.
What is conjugation?
Two bacteria of the same species attach to each other and combine their genetic material.
What are some ways that bacteria are beneficial to the environment?
Bacteria relys on dead material organic waste and nitrogen to make proteins.
What occurs when a virus becomes latent?
Latent viruses go through an inactive stage and does not show its symptoms until later on.
Does bacteria need oxygen to survive?
How does conjugation increase the genetic diversity of bacteria?
DNA is transferred between the bacteria. New combinations of genes, increasing genetic diversity.
What is bioremediation?
Uses organisms, such as bacteria, to clean up environmental pollution.
How does pasteurization affect human health?
Due to pasteurization food poisoning is much less common today.
What is the importance of an antibody?
