Answer
Enzymes involved in photosynthesis are disrupted at temperatures above
, which slows down the rate of photosynthesis.
Solution
To determine which statement explains the effect of temperature on the rate of photosynthesis, let’s analyze each option:
(A) Oxygen molecules break down at temperatures above
: This statement is incorrect. Oxygen does not break down due to temperature; rather, it is a product of photosynthesis.
(B) The rate of photosynthesis is unaffected by the temperature of the water: This statement is misleading. Temperature can significantly affect the rate of photosynthesis, as it influences enzyme activity and metabolic processes.
© The number of chloroplasts in the cell decreases as temperature increases: This statement is not accurate. The number of chloroplasts is generally stable and does not decrease simply due to temperature increases.
(D) Enzymes involved with plant photosynthesis are disrupted at temperatures above
: This statement is correct. Enzymes are sensitive to temperature, and high temperatures can lead to denaturation, disrupting their function and thus affecting the rate of photosynthesis.
Based on this analysis, the correct answer is:
(D) Enzymes involved with plant photosynthesis are disrupted at temperatures above
.

The Deep Dive
Photosynthesis, the process by which plants convert light energy into chemical energy, is heavily influenced by temperature due to the enzymes that facilitate these reactions. When temperatures exceed optimal levels, typically around
, these enzymes can become denatured, leading to a decrease in the efficiency of photosynthesis and thereby affecting plant health and growth.
High temperatures can also affect the availability of water for plants, which is crucial for photosynthesis. When plants lose too much water through transpiration, they can close their stomata to avoid dehydration, leading to reduced carbon dioxide uptake and a subsequent decline in photosynthesis. This can create a tricky balance where plants must manage both temperature and water availability effectively to maintain optimal photosynthetic rates.
