How Do Flowers Know When to Bloom?

The video explores how plants in the northern hemisphere know when to bloom in spring. It explains that plants respond to environmental cues like daylight and temperature, which stimulate flowering. Scientists have discovered that a special type of RNA, once thought to be a hormone called florigen, is responsible for signaling plants to flower. This RNA travels from leaves to meristems, activating genes that switch from leaf production to flower production. However, climate change is disrupting this process, causing plants to flower earlier, which can affect their synchronization with pollinators and the ecosystem. The video concludes with acknowledgments to supporters and encourages viewers to subscribe.
