Answer:
Leaves and flowers serve important functions for plants:
Leaves are the primary sites of photosynthesis, where plants use sunlight, carbon dioxide, and water to produce glucose, the plant's food source. Leaves also have structures that allow for gas exchange - pores called stomata that facilitate the intake of carbon dioxide and release of oxygen and water vapor. Additionally, leaves play a role in transpiration, the evaporation of water from the plant.
Flowers are the reproductive structures of plants. Their main function is to facilitate pollination, the transfer of pollen from the male parts (stamens) to the female parts (pistils) of the flower. Once pollination occurs, the flower can develop into fruit containing seeds. Flowers also often serve an attractive function, using colorful petals, scents, and nectar to lure pollinators like bees, butterflies, and hummingbirds to enable pollination.
