Angiosperms, or flowering plants, evolved most recently (approximately 120 million years ago). However, they are also the most diverse group of plants! This is because they have co-evolved with their pollinators (insects, birds, and mammals). The specificity of their pollinators caused reproductive isolation of different groups of a single species, ultimately causing the formation of new species over time. Many flowering plants are pollinated by just a single species of pollinator (such as a species of moth or a hummingbird). You should have no trouble finding flowering plants, and remember, they don't always have their flowers present. Flowering plants include flowering trees, grasses, shrubs, and the typical types flowers you find in garden stores. Here are some examples of flowering plants, and in the top left the parts of the flower are labeled:
Angiospermas, o plantas que florecientes (tienen flores) , son los que evolucionaron lo más reciente--hace apróximadamente 120 millones de años. Son un grupo muy diverso de plantas. Las angiospermas han co-evolucionados con sus polinizadoras (incectos, mamíferos y pájaros). Aquí hay unos ejemplos de plantas que tienen flores.
