Question

An ecologist examining the leaves of a diseased plant wonders if the fungus found on its roots is the pathogenic organism. Which step would be least necessary in order for the scientist to confirm that the fungus is responsible for the disease

Answer 1

See the answer below

Step-by-step explanation:

It seems like you forgot to include the available options in order to answer the question.

However, according to plant pathologists, in order to establish that a particular organism is responsible for a certain observable disease, certain conditions have to be fulfilled. These conditions include:

• All plants showing the symptoms of the disease must have the organisms on their bodies.
• The organisms must be able to cause healthy plants to be diseased with the same symptoms as the original disease.
• Manually infected plants must show the presence of the organism

Any other condition that is short of the above-listed conditions can be considered to be least necessary in order for scientists to confirm if an organism is responsible for a particular disease.
