Do Plants Smile? Science Behind Plant Behavior!

Happy plants do smile, but not the way that you think. They express happiness by growing without any troubles when all their requirements are met!

Generally, plants can not talk or smile as they lack nervous systems or brains. However, plants respond to these external stimuli through root development, growth patterns, and gene expression.
Read on to learn more about smiling plants and their behaviors. 

Do Plants Respond To Talking?

Plants do not respond to talking the same as animals. 

In fact, plants lack nervous systems or brains, so they cannot perceive and process sounds like animals.

However, certain reactions like vibrations and sound waves are found to affect the plants.

These stimuli change plants’ root development, growth patterns, and even gene expression.

Here are some reasons why to talk to plants.

  • When we talk to the plants, they can sense vibrations of sound waves through the air, which can help the plants to secrete growth-promoting hormones.
  • Talking to the plants makes a way of communication with them, which can be helpful in promoting their growth.
  • When we talk to the plants, we give them importance, improving their growth.

However, talk to your plants calmly and soothingly, use positive words and phrases, and ultimately be friends with them.

Do Plants Respond To Music?

As plants can sense the vibrations of sound waves of music, furnish them with moderate volume kinds of music.

Moreover, some studies have revealed that placing the speakers near plants affects their growth.

But the type of music depends on the plants’ type. You can research and experiment on what type of music your plants want.

Additionally, talking to your plants nicely has a better impact on plants than talking to them rudely.

But there is no scientific evidence of this thing. 

Some people believe that when you talk to your plants nicely, they grow healthier and faster.

However, some people say that talking to plants when we are stressed transfers negative energy to the plants, which can retard the growth of plants.

Do Plants Have Feelings When Cut?

Plants do not react to cuts as animals do, but they show their reactions in a different way.

Plants defend themselves from external attacks by secreting some phenolic compounds, like polyphenols and ketones.

These chemicals defend themselves by preventing the entry of microbes into the wounds.

Furthermore, plants are able to sense injuries, and the response is similar to the pathogen attacks.

Some ways in which plants defend themselves when they are cut are mentioned below.

  • Plants secrete some phenolic compounds, like polyphenols and ketones, that prevent microbial infections in the wounds.
  • Plants initiate the rapid formation of new cells to heal the wounds.
  • They deposit callose (mass of carbohydrates) around the wounded cells to prevent the spread of pathogens.

Do Plants Smile? Let’s Find Out!

No, the plants do not smile. 

A smile is a facial expression that is caused by contractions of certain facial muscles occurring in animals.

But plants do not have those muscles. Due to this reason, plants do not smile.

However, plants can sense the vibrations of sound and the care they are receiving.

They react to the senses through their growth pattern and root development.

Furthermore, some flowers are said to be smiling, such as Sunflowers, Tulips, and Daisies.

Scientifically, there are no flowers that make you smile when you die. However, some flowers serve the symbol of death.

Similarly, some cultures consider the Jasmine flower the symbol of death.
