Answer:
The prokaryotes uses organ called Pilus during conjugation process.
Explanation:
Pilus is a long thread like appendages which seen in the capsules of the bacteria. During conjugation process, the pilus from the donor bacteria extends and gets attached to the recipient bacteria.
The shared pilus acts as the bridge between the donor as well as the recipient bacteria through which the exchange of genetic information occurs. Thus it can be inferred that during conjugation prokaryotes uses pilus.
Answer:
Fluorescent labeling of cells helps in ensuring more visibility of the properties of the cell.
The equipment used in studying fluorescence-labelled cells include epi-fluorescence microscope which helps in providing a more dimensional view of the cells. The spectrophotometers is also used to determine the chemical properties of the cells through the intensity of light measured with this equipment. The flow cytometer is also used in this process.
