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 of the species A plant?

Question

Quizplus · Accepted Answer

The pollen to ovule ratio (P/O) for species A is calculated by dividing the number of pollen grains by the number of ovules. For species A, this is 10,000 pollen grains per 100 ovules, which simplifies to 100:1, or a ratio of 100.
