They can bend and twist to reach the sunlight…without muscles ?
In: Biology
in addition to the previous answers, plants can move by pumping ions (specifically potassium ions) into some of their tissues. This forces water into the tissues with extra potassium which changes the pressure of the tissue and makes plants bend! That’s how plants can track the sun and open and close their petals. If you want to research further, the tissue involved is called pulvinus.
