Hey, it's me, do you ever think about plants thinking? We humans, as well as animals, think before doing something so does that means plants think too
First, we need to know do they really need the ability to think. We know that plants are immobile so they can`t move. What do you do when a lion is coming you`re way you run but plants can`t run when they meet hungry cattle. They can think but not as advanced as we can.
PROPRIOCEPTION Proprioception is the ability to sense direction. plants have this that's why the roots don`t grow upwards and shoots don`t grow downwards. A plant knows in which direction to grow. They have cells called statoliths which lie at the tip of the root. They can sense gravity so the root grows below the ground.
SMELLING: Have you ever seen you`re mother putting a ripe banana with unripened ones in a bag. After a few days the all the bananas will be ripe. This is because plants can smell. The ethylene gas is the ripening Hormone for fruits. When one fruit ripens the other fruits sense the ethylene gas and ripe faster.
WARNING SIGNALS When there is an insect invasion the plants warn others. When an insect chews on one leaf. That leaf lets out chemicals the other leaves sniff out those chemicals and produce toxins that are harmful to the insects.
TOUCH When a vine touches a tree it starts winding around it. This sense of touch is incredibly sensitive that even rubbing a bristle of a brush could activate it.
MEMORY When you drop a touch me not plant it closes. this response is to scare away insects. In a research, they dropped the leaf of the plant. After weeks of throwing the plant from the same height about 5 cm, it stopped closing. It is because it realized the stimulus was not harmful.
