Question 6

Agrobacterium infects plants and causes them to form tumors. Tumor formation requires a large amount of the plant's energy for tissue formation. What could be the possible impact of tumor formation on plant reproduction? And why?

Accepted Answer

A)  The number of offspring should increase because in general, illness increases the reproductive output of organisms. 
B)  The number of offspring should increase because the bacteria will provide energy for the plant. 
C)  The number of offspring should decrease because the plant will divert energy from reproduction to tumor formation. 
D)  There should be no effect of infection on offspring production because energy for reproduction is independent of infection. 
A)  The number of offspring should increase because in general, illness increases the reproductive output of organisms. 
B)  The number of offspring should increase because the bacteria will provide energy for the plant. 
C)  The number of offspring should decrease because the plant will divert energy from reproduction to tumor formation.
