What adaptation found in tundra plants would BEST help them maximize the available sunlight?

Tundra plants have adapted to maximize available sunlight primarily through their low growth form, which allows them to stay close to the ground and receive sunlight while minimizing exposure to harsh winds. Additionally, many tundra plants have dark-colored leaves that can absorb more sunlight, and some exhibit a growth habit that orients their leaves towards the sun to optimize light capture. These adaptations help them thrive in the short growing season of the tundra.
