Answer:

Grow the seedlings of oats for Avena coleoptile test in a petri plate and let them germinate in light, so that the coleoptile forms with leaves.Cut the coleoptile stem and add agar block of auxin with different concentrations in all different oat seedlings and expose them to sunlight.Then observe the amount of bending of coleoptile stem towards the light in different samples added with different amount of auxin in the agar slab.

Cultivate oat saplings in a petri dish for the Avena cotyledon experiment and let them germination in light until the coleoptile develops with branches.

Cut the coleoptile stems and place an agar blocks with varying quantities of auxin in each of the oat saplings before exposing them to sunlight.

Next, in separate samples with varied amounts of auxin inside the agar slab, examine the degree of bending of the coleoptile branch more toward the sunlight.
