Structure
The majority of genetic material is contained in this very long molecule.
What is the DNA / a chromosome?
The reproduction process of bacteria.
What is binary fission?
The process of extracting energy from food when oxygen is present.
What is aerobic respiration?
Bacteria secrete these to break down food outside the cell.
What are digestive enzymes?
Some bacteria have this tail-like structure to move.
What is a flagellum?
Under ideal conditions bacterial cells split every ____ minutes.
15-20
The process through which glucose is broken down into waste products like ethanol, lactic acid or hydrogen.
What is fermentation?
The feeding process of most bacteria where food is broken down outside the cell.
What is extracellular digestion?
A small ring that contains some of the bacterial DNA.
What is a plasmid?
The result of bacterial reproduction. They are identical to the mother cell.
What is a daughter cell / are 2 daughter cells?
What is missing?
C6H12O6 + ______ --> CO2 + H2O + energy
What is O2 / oxygen?
Bacteria that make their own food (via photosynthesis or chemosynthesis).
What are autotrophs?
The outermost layer of bacteria.
What is a capsule / slime layer?
During this phase, toxic waste builds up. Conditions become unfavourable for maintaining life.
What is the death phase?
What is missing?
Glucose --> ethanol + _____________
What is carbon dioxide / CO2?
Digested food moves into the bacterial cell through this process.
What is diffusion?
These round bacteria form chains making them look like a string of pearls.
What is a streptococcus?
During this phase, growth conditions are ideal. Bacteria grow rapidly.
What is the exponential phase?
What is lactic acid?
These bacteria live on dead matter, cause decomposition and decay. They spoil food.
What are saprotrophic bacteria?
