Pronunciation: [kəɹˈə͡ʊləz] (IPA) 
The word "corollas" is spelled with two L's despite the pronunciation being "ko-roh-uhz" with only one L sound. This is because the word is derived from the Latin word "corolla" which has two L's. In English, words borrowed from Latin often keep their original spelling even if the pronunciation changes. So, when encountering the word "corollas," remember to use two L's even though you only hear one "L" sound.
Corollas, in botany, refer to the floral whorls that surround the central reproductive organs, known as the pistil and stamen, in flowering plants. More specifically, they are the structure formed by the collection of petals, which are the colorful, often petal-like, modified leaves of the flower. Corollas play a crucial role in attracting pollinators, such as bees, birds, or insects, by providing a visually appealing display and sometimes emitting enticing scents.
The corolla is usually positioned between the outermost whorl of green sepals, called the calyx, and the innermost reproductive structures. Together with the sepals, the corolla helps protect the developing flower bud during its initial stages. As the flower matures, the sepals and corolla may separate, and the corolla's main function becomes promoting pollination. Its bright colors and distinctive patterns, often along with nectar-producing glands, serve as visual and olfactory signals to attract specific pollinators.
Corollas can exhibit great variation in size, shape, color, and structure across different plant species. They can be tubular, bell-shaped, trumpet-shaped, or have multiple lobes. Some flowers may have separate corollas that consist of individual petals, while others may have a fused corolla forming a single tube or structure. The corolla is an important feature used in plant taxonomy and classification to differentiate various plant families and species.
In summary, corollas are the collection of petals in a flower, serving both protective and reproductive functions. They are crucial in attracting pollinators, promoting successful pollination, and exhibit considerable diversity in their appearance across the vast world of flowering plants.
The word "corollas" is the plural form of "corolla". The etymology of "corolla" is from the Latin word "corolla", which means "little crown" or "garland". In botany, the "corolla" refers to the innermost whorl of a flower, consisting of the petals. The term "corolla" describes the crown-like appearance of these petals, which surround the reproductive structures of the flower.
