Open and Close

Have you ever wonder how a plant protects itself? Well, a plant respond by activating a defense programs that scares or kills the attacker. This defensive system of the plant uses a lot of energy and stops the growth of the plant. Hormones play an important role in this. Plants produce them when they are in a stressed condition. When jasmonates is presence, the breakdown of JAZ proteins begins. This frees a protein call MYC2 which signals for the defensive system and stops the plants growth. Three proteins: NINJA, JAZ, and TPL works together to activate the defensive system. When those three is together, MYC2 remains inactive. But when JAZ protein disappears, MYC2 becomes active.

This relates to the biology concept by that this is the function of the plant. This is how the plants work when diseases try to get in. A plant is pretty much like a human. Only we have white blood cells to help fight diseases. But when MYC2 is activated, the plant stops growing due to the extra energy needed to fight the disease.

This is important because there is still a lot we do not know about other organisms and how they function. There is organisms that might not even been discovered. All organisms need each other to survive. With too much or too less of something will harm the environment and we are already doing it.
