Photosynthetic Rates of Plants Under Light Wavelengths

Very Hard Research Summaries Interpreting Results

A study was conducted to investigate the effects of different light wavelengths on the photosynthetic rate of two plant species: Plant A, a typical green plant, and Plant B, a species that thrives in shaded environments. The researchers exposed samples of each plant to red, blue, and green light for a duration of 24 hours. The photosynthetic rate was measured in terms of oxygen output (milliliters per hour) at the end of the exposure period.

The following results were obtained:

Light Wavelength	Plant A (ml O₂/hr)	Plant B (ml O₂/hr)
Red	15	5
Blue	25	10
Green	10	7

Based on these results, which conclusion can be drawn regarding the photosynthetic efficiency of Plant A and Plant B under different light wavelengths?

Plant A exhibits a higher photosynthetic rate under all light wavelengths compared to Plant B.

Plant B shows a maximum photosynthetic rate in blue light, outperforming Plant A in this wavelength.

Both plants have similar photosynthetic rates under green light conditions.

Plant A's photosynthetic efficiency decreases more than Plant B's as the light wavelength changes from red to blue.
