Scientists Have Various Methods of Investigating Reproductive Methods in Plants

Scientists have various methods of investigating reproductive methods in plants. One way is to examine pollen to ovule ratios (P/O) . This ratio indicates the likelihood of a pollen grain reaching the female component of the same species of plant. Species A plant releases approximately 10,000 pollen grains per 100 ovules, whereas species B plant releases approximately 1,000,000 pollen grains per 100 ovules. What is the pollen to ovule ratio for species B?

A) 100
B) 10,000
C) 100,000
D) 100,000,000
