In the radish seed experiment, what is happening in the number 3 Petri dish with seeds that received water, but no sunlight?

Question

BlackTom AI · Accepted Answer

The question asks about what is happening in the number 3 Petri dish where seeds received water but no sunlight during a radish seed experiment.
Option 1: 'the seeds germinated in the presence of water, and produced CO2 using cellular respiration' This is correct because in darkness, seeds cannot perform photosynthesis. They rely on stored reserves and cellular respiration to convert those reserves into energy, releasing CO2 as a byproduct. The description aligns with the expected metabolic process during germination without light.
Option 2: 'the seeds germinated in the presence of water, and fixed CO2 using photosynthesis' Photosynthesis requires light and chloroplasts; in the absence of sunlight, photosynthesis cannot occur, so CO2 cannot be fixed. This makes the statement incorrect for a dark germination scenario.
Option 3: 'the seeds germinated in the presence of water, and produced O2 using photosynthesis' Producing O2 is a hallmark of photosynthesis, which does not happen without light. In darkness, photosynthetic O2 generation is not occurring, so this option describes an impossible process under these conditions.
Option 4: 'the seeds germinated in the presence of water, and fixed CO2 using cellular respiration' Cellular respiration releases CO2, not fixes it. Fixing CO2 is a photosynthetic process, which would not be happening here due to the lack of light. This option mixes up the direction of the carbon transfer and is therefore inaccurate.
In summary, only the first option properly describes germination with water in the dark, where respiration releases CO2, while the others misattribute the processes or rely on light-dependent steps that aren’t present in this setup.
