A student sets up an investigation by placing a plastic bag over a plant. she secures the plastic bag so that it is completely sealed and nothing can enter. she observes the plant daily to see if it remains green and healthy. which two questions is this investigation designed to answer?

Respuesta :

When a plant is wrapped in and tied to a plastic bag, it eventually dies due to starch depletion.  The plant requires carbon dioxide and water to produce food in the presence of sunlight via the photosynthesis process aided by chlorophyll.

Plants protected by plastic bags retain moisture and even capture what transpiration produces. However, don't use plastic bags as a greenhouse for succulents because they can tolerate neglect but not this level of moisture.

Plastics such as vinyl and traditional camping tarps are not breathable, allowing moisture to accumulate inside. The plastic can actually stick to the leaves depending on its thickness.
