Deep inside plant cells there are microtubules which may be useful for regulation of precognitive pathways implicated in vision processing!Microtubules are universal across all the kingdoms of life on Earth, carrying out essential functions in the cell such as:
- Skeleton: Maintain the shape of the cell
- Muscles: The basis of cell movement
- Circulatory system: Moves nutrients around inside the cell
- Reproduction: Microtubules guide chromosome division
Two items missing from this extensive list is "vision" and "cognition".
- At the cellular level, cognition means detecting external stimuli (chemical, electrical, optical, etc), and responding to them (chemical, electrical, movement, etc). The cognitive aspects are managed by triggering gene expression in the nucleus. This then triggers changes in the cell, which may include lengthening or shortening microtubules.
- Light detection is managed by chloroplasts in plants, and specialist rod/cone cells in mammals. But image detection requires the coordination of light detection across many cells, which is handled in a central brain in animals, but appears to have no central coordination in plants - it is a distributed system.
