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. Based on the pollen to ovule ratios, which statement appears to be true?

Species B, with a much higher pollen to ovule ratio, likely relies on wind distribution, which is less efficient and requires producing a large amount of pollen to ensure that some reaches the female parts of plants.
