Kingdom Plantae - Gymnosperms

Gymnosperms are seed-bearing, non-flowering plants with exposed seeds. They include conifers, cycads, Gnetales, and Ginkgo. Gymnosperms have taproots with symbiotic associations, and their leaves are adapted to reduce water loss. The main plant body is a sporophyte, and they produce microspores and megaspores on cones. The reproductive process involves pollen grains contacting ovules, leading to fertilization and embryo development.

What is the role of the megaspore mother cell in gymnosperms?
