Analysis of the nucleotide sequences of genes coding for phytochrome pigments suggest that the ancestors of angiosperms were adapted for survival in ____.

Question

Quizplus · Accepted Answer

Phytochrome pigments are involved in plant responses to light, particularly in shade avoidance and photoperiodism. The suggestion that the ancestors of angiosperms were adapted for survival in shady forests comes from the observation that these pigments help plants optimize light capture in low-light environments, indicating an evolutionary adaptation to such conditions.
