The body of E. viridis is partially translucent to allow light energy to reach intestinal cells.
Explanation:
According to the table, control E. viridis gained mass and maintained their length over the study period. Both light-starved and dark-starved E. viridis lost weight over the study, but the light-starved E. viridis lost less weight than the dark-starved E. viridis. Light-starved E. viridis also grew longer, while dark-starved E. viridis grew shorter. These findings suggest that in the presence of light, E. viridis can produce some of the materials they need to survive through photosynthesis in the chloroplasts.
Photosynthesis requires an input of energy from light. So, it is likely that the body of E. viridis is partially translucent to allow light energy to reach intestinal cells.
