Is it towards the Sun at morning, evening or midday?
What direction is “towards the Sun”?
Heliotropism is the turning of the leaves, like little solar panels, so that they are perpendicular to the incoming sunlight. This is caused by hydraulic pressure in the stems.
A sunflower faces east in the morning and west in the evening; which direction is it growing?
If you go back to my original comment, you will see I said:
“It will bend to keep growing towards the maximum source of sunlight.”
That is, in a shorter form, exactly what you keep stating to me, and yet you say I am wrong.
If you put a source of sunlight (or artificial light) say, to the side of a plant, it will turn and grow in that direction.
Is this not true?
