In the scenario of sealing a house plant in a transparent glass container, the most likely factor that could lead to the plant's death would be a lack of carbon dioxide.
While the plant will initially be able to use the carbon dioxide present in the container for photosynthesis, over time this supply will diminish, and the plant requires carbon dioxide to produce sugars through photosynthesis. Although light is available in a transparent container, and the plant produces oxygen during the day, eventually, the depletion of carbon dioxide will hinder the plant's ability to carry out photosynthesis, which is essential for its survival.
