Yes, sunflowers exhibit a behavior called heliotropism, where they track the movement of the sun across the sky during the day. This movement helps them maximize their exposure to sunlight for photosynthesis.
Sunflowers are named so because they look like sun (If one draws
a sun) .Sunflowers have yellow petals coming from center towards
the edge forming a circular flower like shape and also representing
sun rays.
Growing Sunflowers (Young) follow the sun during the day time
and always try to face it. More movement is seen with leaves as
they try to get more of the sunlight for photosynthesis and grow
fast.
