Can plants count from 1 to 10 using their root tendrils? No. However, researchers have discovered that some plants possess the fascinating ability to detect insect intruders and monitor their own food supply, allowing them to perform basic counting and mathematics.

Take, for instance, Venus flytraps, which are renowned for snapping shut when they detect movement from an insect or other triggers. Interestingly, this is only activated if the object moves twice within a time frame of approximately 15-20 seconds.

These movements are captured by delicate “trigger” hairs on the leaves, which convert the sensory input into electrical signals that travel through the plant as waves of charged atoms (ions). The leaves then close upon receiving two triggering electrical signals.

Additionally, a group of international scientists noted in a 2016 exhibition that Venus flytraps can tally multiple counts before reacting.

They wait to receive a minimum of three electrical signals before producing the necessary enzymes to digest their prey, potentially to avoid wasting energy on false alarms.

Even prior to this finding, scientists had proposed that the mustard plant (Arabidopsis), a common research subject, exhibits behaviors akin to division.

During daylight hours, plants harness sunlight to accumulate food stores (starches) through photosynthesis.

To sustain themselves overnight, they must establish a balanced starch consumption rate (starch divided by time) by gauging the starch stored in their leaves alongside their circadian rhythms.

Experts caution against labeling these unique counting abilities as “intelligent” or indicative of a primitive brain structure; instead, they are vital survival mechanisms that demonstrate remarkable sophistication.
