Monstera deliciosa, commonly known as the Swiss cheese plant, is renowned for its striking foliage and ease of care, making it a popular choice among indoor plant enthusiasts.
A common query among plant owners is whether Monstera deliciosa releases oxygen or carbon dioxide during the night.
To address this question, we need to explore the fundamental processes of plant respiration and photosynthesis and how they apply to Monstera deliciosa.

Photosynthesis and Respiration: Understanding Plant Processes

Plants, including Monstera deliciosa, engage in two fundamental biological processes: photosynthesis and respiration. Photosynthesis, which primarily occurs during daylight, involves converting carbon dioxide (CO₂) and water into glucose and oxygen (O₂) using sunlight. During this process, plants absorb CO₂ from the atmosphere and release O₂, a critical component for human and animal respiration.
Respiration, in contrast, is a continuous process that occurs both day and night. During respiration, plants take in O₂ and release CO₂ as they break down stored glucose to generate energy for growth and maintenance. Unlike photosynthesis, respiration does not rely on sunlight and occurs in the mitochondria of plant cells. This energy production is vital for the plant’s survival and functionality.

Nighttime Plant Activity: Monstera Deliciosa's Role

At night, Monstera deliciosa, like all plants, ceases photosynthesis due to the absence of sunlight. Instead, it continues to respire, consuming O₂ and releasing CO₂. The amount of CO₂ released is relatively small compared to the room’s total air volume and typically has a negligible effect on indoor air quality.
It’s important to note that the CO₂ produced by Monstera deliciosa during nighttime respiration is significantly outweighed by the oxygen generated through photosynthesis during the day. This makes the overall contribution of indoor plants to air quality beneficial, reinforcing their value in creating healthier and more vibrant living spaces.

Impact on Indoor Air Quality

When considering indoor air quality, the impact of Monstera deliciosa and other houseplants is minimal yet positive. While plants release small amounts of CO₂ at night as part of their natural respiration process, they provide numerous benefits, such as improving humidity levels, reducing airborne dust, and potentially enhancing overall well-being.
Research indicates that indoor plants contribute to creating a more pleasant and inviting living environment by adding aesthetic value and fostering a sense of tranquility. Concerns about nighttime CO₂ emissions can often be put into perspective, as the amount released by a single plant is negligible compared to the CO₂ generated by humans and animals in the same space.
To mitigate any concerns, proper ventilation in indoor areas is highly recommended. Ventilation ensures a continuous exchange of air, maintaining healthy indoor air quality while allowing plants to thrive.
Monstera deliciosa may release carbon dioxide at night, but its primary function remains its ability to absorb CO₂ and release oxygen during the day through photosynthesis. The numerous benefits of houseplants, including their contribution to a calm and vibrant atmosphere, far outweigh any minimal nighttime emissions.
