Within the microsporangium, the microspore mother cell divides by meiosis to give how many microspores?

1. Pollen develops in the microsporangia, the usually bi-lobed pollen sacs found in the anther. 2. Inside a microsporangium the microspore mother cell divides by meiosis. 3. That division gives rise to four microspores. 4. Each microspore will ultimately form a pollen grain, so one mother cell yields four grains. 5. Any other count would break the standard result of a meiotic division producing four products. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 32 "Plant Reproduction", section 32.1 Reproductive Development and Structure_
