उत्तर

This statement is false.

Explanation:

Photosynthesis does not instantly stop above 35°C; rather, its rate begins to decline for most temperate plants because high heat degrades critical enzymes like RuBisCO. However, many tropical plants reach their maximum photosynthetic efficiency between 35°C and 40°C, and heat-tolerant desert species can carry out the process effectively at even higher temperatures. Total cessation occurs only when extreme heat permanently denatures proteins and completely disrupts chloroplast membranes.
