Heliophytes or sunstroke plants are adapted to a habitat with a very intensive insolation by their structure and metabolism.
They are common in open terrain, rocks, meadows, as well as at the mountain pastures and grasslands and other long sunny exposures.
[1][2] Special features of such plants include coarse tiny leaves with hairy and waxy protection against excessive light radiation and water loss.
Chloroplasts have a protective element such as carotenoid and the enzymes, and accumulation of ROS to avoid toxic effects.
[3][4] Unlike shade-preferring plants (sciophytes), heliophytes have a high light compensation point, and for this they need a higher illumination intensity for effective adoption of carbon dioxide.
