The spores that produce microgametophytes are called microspores.
The dots on a fern plant's leaves are called sori. Sori are clusters of sporangia, which are structures that contain and release spores for reproduction.
Plant leaves have tiny spores called stomata through which air enters and water exits the plant.Stomata is plural (stoma is singular)

One great example for a plant the produces spores are Ferns.
There new plants are called gametophtes
Plants produce spores during the gametophyte, or haploid, stages. Spores are the sex cells for the plant. The spores will then germinate and produce new plants.
Your pepper plant leaves may be turning white due to a fungal disease called powdery mildew, which is common in plants grown in humid conditions. This disease appears as a white powdery substance on the leaves and can be treated with fungicides or by improving air circulation around the plant.
