Q. After their experiment, the Darwins concluded that grass stems bend toward light because:


The epidermis senses light and absicisic acid builds up on the dark side of the stem.
The vascular bundles sense light and abscisic acid builds up on the side of the stem facing the light.
The tip of the coleoptile senses light and auxin builds up on the dark side of the stem.
The palisade parenchyma sense light and auxin builds up on the dark side of the stem.
The base of the coleoptile senses light and abscisic acid builds up on the side of the stem facing the light.
