What is biotechnology
Biotechnology is the use of living organisms, cells, or biological processes to create useful products and solve problems.
What type of cells do bacteria have?
Bacteria are prokaryotes, meaning they do not have a nucleus.
What is fermentation?
Fermentation is a process in which cells break down sugars to release energy without using oxygen.
What is the difference between prokaryotic and eukaryotic cells?
Prokaryotic cells do not have a nucleus, while eukaryotic cells have a nucleus that contains their DNA.
How do bacteria reproduce?
Bacteria usually reproduce through binary fission, a process in which one cell divides into two cells.
What organisms commonly carry out fermentation?
Yeast, certain bacteria, and muscle cells can carry out fermentation.
What is the purpose of DNA in a cell?
DNA stores the genetic information that tells cells how to function, grow, and reproduce.
What is the difference between Gram-positive and Gram-negative bacteria?
Gram-positive bacteria have a thick peptidoglycan cell wall and stain purple, while Gram-negative bacteria have a thinner peptidoglycan layer and stain pink or red during Gram staining.
What are the two main types of fermentation?
he two main types are lactic acid fermentation and alcoholic fermentation.
How are microorganisms used in biotechnology?
Microorganisms are used to make products such as yogurt, cheese, antibiotics, and insulin.
What do bacteria need to grow?
Bacteria need nutrients, water, and suitable environmental conditions, such as the right temperature and pH, to grow.
What is alcoholic fermentation?
Alcoholic fermentation is a process in which yeast converts sugar into ethanol (alcohol) and carbon dioxide.
What is genetic engineering?
Genetic engineering is the process of changing an organism’s DNA to give it specific traits or make it produce useful substances.
What is the role of bacteria in the environment?
Bacteria help decompose dead organisms, recycle nutrients, and maintain healthy ecosystems.
What gas is produced during alcoholic fermentation?
Carbon dioxide is produced during alcoholic fermentation.
