Which type of plant group needs help from birds or insects?

Flowering plants, or angiOSperms, often rely on birds and insects for pollination. These animals transfer pollen from one flower to another, facilitating fertilization and seed production. Many flowering plants have evolved specific traits, such as bright colors, sweet nectar, or appealing scents, to attract these pollinators. This mutualistic relationship is crucial for the reproductive success of many plant species.
