In a bisexual flower, the different parts of the flower serve specific functions:
1. Petals: The petals attract pollinators such as bees, butterflies, and birds. Their bright color and fragrance help in the process of pollination.
2. Anther: The anther produces pollen, which contains male gametes (sperm cells). This pollen is transferred to the stigma for fertilization to occur.
3. Style: The style is the long tube that connects the stigma to the ovary. It provides a passage for the pollen tube to travel down to the ovary during fertilization.
4. Ovary: The ovary contains ovules, which are female gametes (eggs). After fertilization, the ovary develops into a fruit that contains the seeds.
