Rose Flower Rosaceae plants grow as trees, shrubs, and perennial herbs. They also grow as climbing plants, like vines, but don’t cling or climb up. There are 5 sepals united at the base, 5 petals rising from the top of a saucer- like structure, numerous stamens and one compound ovary. The petals are a good source of Vitamin C for people.
Flower Info. • There are over 3,000 species in the rose family and about 107 genera worldwide. • They are found on all continents except Antarctica, but the majority are found in Europe, Asia, and North America. • They have been in existence for about 35 million years. • Leaves are simple and alternate. • Flowers are radially symmetrical and have male and female structures (perfect).
Fruits There are different types of fruits, like single-seeded, soft, fleshy, as well as drupes. The mature pseudocarp (pome or hip-type of fruit), the true fruit, is located in the center and has 5 distinct carpels which contain seeds. The fruits serve as sources of nutrition for many wild animals. The pomes, drupes, and aggregate fruits attract animals to eating the fruit, making the seeds ingested or disposed of. Leaves: alternate and simple with stipules Stems: changing, climbing Flowers: regular and showy.
Pollination and Structure Epicalyx is composed of 5 sepal-like structures which occur below and alternate. Anthers have two chambers, called locules, holding thousands of pollen grains. Most species have large, white, pink, or red petals which are designed to attract pollinating insects.
