Which scientific question did Jan Ingenhousz seek to answer through his experiments with plants?
A
Do plants produce oxygen in the presence of light?
B
Do plants absorb carbon dioxide at night?
C
Can plants grow without soil?
D

Verified step by step guidance1
Step 1: Begin by understanding the historical context of Jan Ingenhousz's experiments. He was a scientist who conducted groundbreaking research on photosynthesis in the late 18th century.
Step 2: Recognize that Ingenhousz's experiments focused on the role of light in plant processes. He observed that plants produce bubbles (oxygen) when exposed to sunlight, but not in the dark.
Step 3: Analyze the options provided in the question. The correct scientific question should align with Ingenhousz's focus on light and oxygen production during photosynthesis.
Step 4: Eliminate options that do not pertain to light or oxygen production. For example, questions about carbon dioxide absorption at night or soil requirements are unrelated to his experiments.
Step 5: Conclude that the scientific question Ingenhousz sought to answer was: 'Do plants produce oxygen in the presence of light?' This aligns with his observations and findings about photosynthesis.
