Catkins
Catkins are slender, cylindrical flower clusters that appear on certain trees and shrubs, primarily in the spring. They are often found on species like willows, birches, and oaks. Catkins are typically unisexual, meaning they can produce either male or female flowers, and they do not have petals. Instead, they are made up of small, scale-like structures that help in the reproduction process.
The male catkins release pollen into the air, which is carried by the wind to fertilize the female flowers. After pollination, the female catkins develop into seeds or fruits. Catkins play a crucial role in the life cycle of these plants, contributing to their reproduction and the overall ecosystem.
