If you seal a house plant in a transparent glass container, the scenario that would most likely lead to the plant’s death is "a lack of oxygen."
Here's why: While a plant can photosynthesize and produce oxygen during the day if provided with light, it still requires oxygen for respiration, especially at night when photosynthesis is not occurring. If the container is sealed, the plant may eventually deplete the available oxygen in the container, leading to its death.
Although the plant will have access to light and will produce sugars through photosynthesis, the lack of available oxygen would be critical over time.
