• In addition to serving as the reproductive organs of flowering plants, flowers have long been admired and used by humans, mainly to beautify their environment but also as a source of food.
• == Flower specialization and pollination ==
• == Morphology ==
• === Floral formula ===
• ∞: to represent "many"
• A floral formula would appear something like this:
• == Development ==
• === Flowering transition ===
• === Organ Development ===
• == Pollination ==
• === Attraction methods ===
• Still other flowers use mimicry to attract pollinators. Some species of orchids, for example, produce flowers resembling female bees in color, shape, and scent. Male bees move from one such flower to another in search of a mate.
• === Pollination mechanism ===
• The pollination mechanism employed by a plant depends on what method of pollination is utilized.
• Most flowers can be divided between two broad groups of pollination methods:
• Some flowers are self pollinated and use flowers that never open or are self pollinated before the flowers open, these flowers are called cleistogamous. Many Viola species and some Salvia have these types of flowers.
• === Flower-pollinator relationships ===
• == Fertilization and dispersal ==
• == Evolution ==
• == Symbolism ==
• == Usage ==
• * As tokens of love or esteem
• * For wedding flowers for the bridal party, and decorations for the hall
• * As brightening decorations within the home
• * As a gift of remembrance for bon voyage parties, welcome home parties, and "thinking of you" gifts
