If a long-day plant has a critical night length of 9 hours, a 24 -hour cycle of 14 hours light / 10 hours dark would prevent flowering.
Flowering plants are plants that bear flowers and fruits and form clade angiosperms, commonly called angiosperms.
The term “angiosperm” is derived from the Greek angeion (“vessel”) and sperma (“seed”) and refers to plants that produce seeds that are encased in fruit.
By far the most diverse group of land plants, with 64 orders, 416 families, about 13,000 known genera, and 300,000 known species. In earlier days, angiosperms were also called Magnoliophyta.
Many flowers have bright colors, strong scents and sweet nectar to attract pollinators. It can attract insects, birds, mammals and even reptiles.
When visiting flowers, pollinators pick up pollen from the anthers. When pollinators visit the next flower, some of the pollen sheds the stigma. This allows for cross-pollination and increases genetic diversity.
