Quick Summary

A spore mother cell is a biological cell found in spore-bearing plants. Its final divisions produce spores, typically in a group of four called a tetrad. These spore mother cells are located within structures called sporangia.123

Spores are reproductive cells that can develop into new individuals without fusing with another reproductive cell, unlike gametes. They are a form of asexual reproduction found in bacteria, fungi, algae, and plants. In plants, spores are produced by the sporophyte generation and give rise to the gametophyte generation. Meiosis is the cell division process that produces these spores from spore mother cells.425

…vascular plants produce cells called spore mother cells—since they will give rise to spores—in spore cases (sporangia). Spore mother cells are usually surrounded, during development, by a special nutritive tissue. In the more primitive groups, each sporangium holds many mother cells. This is true also in the pollen-producing sporangia of…
