Forming Apples
• Apple blossoms form in Spring (May)• Cross pollinated by bees.• Ovules within the ovary become apple seeds.• The petals from the blossoms fall off & the ovary starts
growing.• The ovary is surrounded by a thin protective layer. This
layer eventually becomes the apple core. • The outer layer surrounding the ovary becomes the
exocarp, or the eating part of the apple. • The calyx, stamens, and pistils become the dry, hairy
part at the bottom of the apple.
