The movement of a tip of a vine
|
The elongating vine looks for something to wind itself around, and it moves around.
The lower photograph, which was taken by exposing the film again and again at 10-minute intervals, shows how the vine changes (from left to right) when it rotates counter-clockwise (sinistral).

A point of observation
Let's examine what parts grow well and which parts grow poorly in the day or the night by moving our attention to the upper part of a vine.
Let's examine another liana and compare them with the morning glory.
According to the overview, the vine of the morning glory turns counter-clockwise as it grows.
