Reading Time: < 1 minuteWe have never seen plants communicate among each other. Plants seem to be more sensitive than they might seem. Plants communicate with each other in wildly complex and remarkable ways. Even though plants stay in one spot, plants are observing and responding to the world around them. A research has shown that when a plant’s […]
How does brain perceive colour?
Reading Time: < 1 minuteHave you wondered why the red apple looks red but not blue or green?
