Special sense receptors inside their leaves
- Plants don’t have eyes to see light like animals or insects, instead they sense light through special sense receptors inside their leaves. These sense receptors can tell a plant if it’s day or night, if it’s summer or winter, and even whether the plant is out in the open or under cover.

The seeds of many plants sprout only after they are exposed to light. This response is carried out by phytochrome signalling. Plants are also able to sense the quality of light and respond appropriately. For example, in low light conditions, plants produce more photosynthetic pigments.
Jul 15, 2020 · Plants can sense light intensities, light quality, light direction, and light duration through photoreceptors that accurately detect alterations in the spectral composition (UV-B to far-red) and are located throughout the plant.
