To analyze:
The effect of damage to the control leaf.
Introduction:
Infectious diseases or infections are caused by pathogens like
Explanation of Solution
A viral infection is either localized or systemic depending on if it is limited to the affected area only or spreads throughout the body of the host, respectively.
While studying the effect of viral infections on plants, some leaves are kept as control (not affected) to compare the changes in the virally infected leaves.
If control leaves are damaged initially, the virus may also enter the control leaves and thus can affect it. This results in loss of control of the experiment and the changes due to viral infection cannot be studied.
If the control leaf was damaged, the viral particle may also infect the control leaf and consequently, the effect of a viral infection cannot be compared with uninfected control.
