10^6 cell but it varies species to species bacterial cell..

The relationship between optical density and bacterial cell count can vary depending on the species, growth phase, and experimental conditions. Therefore, it is not possible to directly equate one optical density reading to a specific number of bacterial cells without calibration against a known standard or a standard curve.

What is the density of bacteria?
The density of bacteria can vary widely depending on the type of bacteria and the environment they are in. However, on average, bacterial density in natural environments like soil or water can range from hundreds to billions of cells per gram or milliliter. In laboratory cultures, bacterial density can be much higher, reaching trillions of cells per milliliter under optimal growth conditions.
How is turbidity of a bacterial culture measured?
The density of the bacterial cells in the liquid suspension. It's an indirect measure of number of cells. Using a spectrophotometer, light is passed through a sample and the light that passes through is measured by a receiver. The idea is that the less light passing through (because of the cloudiness) the more cells there are. The level of turbidity can be called the 'absorbance' or 'optical density (OD)', as measured by a spectrophotometer.
What main parts do bacterial cells have?
The main parts of all bacterial cells are the cytoplasm and the cell envelope.
What main parts do all bacterial cells have?
The main parts of all bacterial cells are the cytoplasm and the cell envelope.
Why do bacterial cells do not undergo meiosis?
Bacterial cell is not eukaryotes... It does not have the defined nucleus.
Does the number of bacteria recorded by the standard plate count method accurately reflect the total bacterial count from the sample?
No, the standard plate count method only measures viable bacteria that can grow under the specific conditions used in the assay. It does not account for non-viable bacteria or those that may not grow under the conditions provided, so it may not provide an accurate reflection of the total bacterial count in the sample.

How is photosynthesis possible in bacterial cells when there are no chloroplast in the cell?
it not possible, because it has no chloroplast. So no chloroplast equals no photosynthesis.
Bacterial cells do not have a genetic material?
no, bacterial cells do not have genetic material

Do bacterial cells have a nuclues?
Bacterial cells are not eukaryotic cells, which means they do not have a nucleus. They do, however, have chromosome.
Is endoplasmic reticulum in bacterial cells?
Bacterial cells lack membrane-bound organelles, including the endoplasmic reticulum, which is a characteristic feature of eukaryotic cells. However, bacteria do have a simpler version of the endoplasmic reticulum called the endoplasmic reticulum-like structure, which helps with protein secretion and membrane biogenesis.
Does the human body have more bacterial or human cells?
it has more human cells actually the human body has more bacterial cells. Although it may seem more likely that the human body would have more human cells than bacterial cells. -Vasillisa
Do bacterial plant and animal cells have walls?
only plant and bacterial cells have walls
How is bacterial cell different from onion cell?
Bacterial cells are prokaryotic and the cells of an onion are eukaryotic.
What named the cells cells?
The 2 are bacterial cells and protists cells
What main parts do bacterial cells have?
The main parts of all bacterial cells are the cytoplasm and the cell envelope.
