Here is a clean Python solution:

def is_palindrome(text: str) -> bool: cleaned = ''.join(c.lower() for c in text if c.isalnum()) return cleaned == cleaned[::-1]

Photosynthesis converts solar energy into chemical energy in plants:

Light-Dependent Reactions: Chlorophyll absorbs photon energy in thylakoids, splitting water molecules (H2O) into oxygen (O2) and creating ATP.
Light-Independent Reactions (Calvin Cycle): Carbon dioxide (CO2) from the air is fixed into glucose (C6H12O6) using ATP.

Overall equation: 6CO2 + 6H2O + Light -> C6H12O6 + 6O2.
