Thale cress seedlings
Videonummer 11930699
| Timelapse footage of gravitropism and phototropism in thale cress (Arabidopsis thaliana) seedlings. This shows competition between negative gravitropism and phototropism. Negative gravitropism is the plant's tendency to grow upwards, against the force of gravity. Phototropism is the habit of plants to grow towards light, which here is coming from below, setting the two forces in unnatural opposition. | |
