Yes, roses absolutely need photosynthesis.
Photosynthesis is the fundamental process by which roses, like all plants, convert light energy into chemical energy in the form of sugars. These sugars are then used as fuel for growth, development, and all other metabolic processes. Without photosynthesis, roses cannot produce their own food and therefore cannot survive.
The reference highlights that even under specific light conditions, such as predominantly blue light, roses can still perform photosynthesis to sustain normal growth. This underscores the essential role of photosynthesis, regardless of light spectrum variations. Although the assimilation rate might be lower under blue light compared to other wavelengths, it still provides sufficient energy for the rose.
In essence, photosynthesis provides the energy for roses to:
- Grow new stems, leaves, and roots.
- Produce beautiful flowers.
- Resist diseases and pests.
- Carry out all their life processes.
Therefore, photosynthesis is indispensable for the survival and thriving of roses.
