Write-up The plant displayed negative Gravitropism . I know this because the stem sprouted upwards against the force of gravity. On the other hand, the roots exhibited positive Gravitropism — it grew downwards in the direction of Earth’s gravitational pull. I noticed that positive Phototropism . took place within the plant. The picture on the previous slide doesn’t do it justice (I didn’t take a pic of the side profile), but the taller stem is slightly bending towards the direction of sunlight. Contrastingly, the roots were negatively Phototropic because it grew away from sunlight.
