Скачать или смотреть Flowers Lab: Ovule & Pollen Development

In this video, you’ll examine the microscopic structures involved in plant reproduction by observing ovule and pollen development in Lilium. Using prepared slides, you’ll investigate where the female and male gametophytes develop and how meiosis leads to the formation of reproductive cells. You’ll compare the protected development of ovules with the mass production of pollen.

In this activity, you will:
✅ Locate ovules within a cross-section of a flower ovary
✅ Identify the megasporangium and funiculus in ovule development
✅ Observe microspore formation within an anther
✅ Compare female and male reproductive strategies in flowering plants

Key takeaway: Angiosperms balance reproductive success by protecting ovule development while producing large quantities of pollen to increase fertilization probability.
