Teaching children the anatomy of a rose can be not only educational, but fun and artistic as well. The study of plants, called horticulture, is a big part of early biology courses. As one of the most prevalent flowers in the world, the rose is a popular source of learning plant biology. While studying the parts of the flower, art projects, drawings and other fun activities can assist in memorisation. Older students can pick their own rose and spend time dissecting and labelling each part, while younger children can simple colour a diagram of each part.
A protective outer layer, sepals are leaves that are present before the rose blooms. As the flower opens, the sepals spread and make room for the flower to open. The sepals serve as protection while the flower is maturing, protecting it from elements like wind, rain and harsh sunlight. Depending on the species of rose, sepals number either four or five.
The most familiar aspect of the rose, its petals are modified leaves. As the main part of the rose, the petals are given additional nutrients, which make it possible to develop the rose's signature colours and smell. The petals are designed to be attractive to bees and other wildlife to aid in pollination.
Found at the centre of the petals, the stigma is the portion of the rose that accepts pollination. It is usually covered in powdery yellow pollen, a substance that contains male sex cells. The stigma is a small lump in the centre of the flower. It sits at the end of a hollow tube that leads down the centre of the rose.
Attached to the stigma, the style is the tubular piece on which the stigma sits. It provides an opening through which pollen makes its way to the ovaries. There are normally between 10 and 12 styles per flower, each of which descend to its own ovary.
Rare amongst flowers, the rose features multiple ovaries. The ovaries sit within the rose hips at the base of the bud. The cavity itself is hollow and filled with ovules. The ovules are the structures that produce the female sex cell, the egg. They are arranged in several lines within the rose.
