Short Notes:

Grass flowers lack petals and sepals. Therefore, instead of attracting insects, grasses rely on wind for pollination.

In most grasses, cross-pollination is ensured because the stamens develop before the stigmas. Some species have separate male and female flowers on a single plant. Separate male and female plants are rare in the grass family.

Grass fruits, called grain, serve as food for the world's population. Wheat, oats, barley, rice, and maize belong to the grass family.
