Answer:
Channelrhodopsin-2 (ChR2), an algal protein from Chlamydomonas reinhardtii, is a light-activated cation channel capable of inducing depolarization and action potentials in neurons. Channelrhodopsins are light-gated ion channels that, via regulation of flagellar function, enable single-celled motile algae to seek ambient light conditions suitable for photosynthesis and survival. These plant behavioral responses were initially investigated more than 150 years ago
