Can People in Vegetative States Photosynthesize?

[Plant People]

1. Humans in a special state. Plant People retain only basic reflexes and metabolism, with no consciousness or ability to think, like plants.

2. Humans who have become plantlike. Plant People do not need to eat or drink. They can survive on sunlight and soil alone, like plants.

Most people are grateful for this evolution, but Feng Minglang isn't convinced.

Is becoming plantlike really a beneficial evolutionary path for humanity? With no pressure to survive, Plant People spend their days basking in the sun, doing nothing and indulging in pleasure. Books and knowledge have been abandoned. Can this really be good for humanity?

More importantly, what exactly do Plant People consume when they convert energy? And are humanoid plants friend or foe? Feng Minglang can't help feeling that there's more to all this than meets the eye.
