8. The Science Behind Calathea’s Prayer Movement

The unique nyctinastic movement of Calathea leaves, often referred to as “prayer movement,” is a fascinating adaptation that has intrigued scientists for years. Understanding the science behind this phenomenon can deepen your appreciation for these plants.

8.1 The Role of Pulvini

The key to Calathea’s leaf movement lies in specialized structures called pulvini. These are swollen nodes located at the base of the leaf stalk (petiole). Pulvini are composed of motor cells that can change their turgor pressure (internal water pressure) in response to environmental cues like light and darkness.

8.2 Mechanism of Movement

When the motor cells in the upper part of the pulvinus gain turgor pressure, they swell and elongate, causing the leaf to rise. Conversely, when the motor cells in the lower part of the pulvinus gain turgor pressure, they swell and elongate, causing the leaf to lower.

This process is regulated by the plant’s internal circadian clock, which controls the rhythmic changes in ion concentrations (such as potassium and chloride) within the motor cells. These ion fluxes drive the movement of water into and out of the cells, thereby changing their turgor pressure and causing the leaf to move.

8.3 Benefits of Nyctinasty

While the exact reasons for nyctinasty are still debated, several hypotheses have been proposed:

Light Capture: By adjusting their leaf angles, Calatheas may optimize light capture throughout the day, maximizing photosynthesis.
Water Conservation: Closing their leaves at night may help reduce water loss through transpiration.
Defense Against Herbivores: Leaf movement may startle or deter potential herbivores.

9. Calathea and Air Purification

Like many houseplants, Calatheas contribute to indoor air quality by removing common pollutants and releasing oxygen.

9.1 Removing Toxins

Studies conducted by NASA have shown that houseplants can effectively remove volatile organic compounds (VOCs) from indoor air. VOCs are emitted by common household items like furniture, carpets, paints, and cleaning products, and they can contribute to health problems like headaches, respiratory irritation, and allergies.

Calatheas can absorb VOCs like formaldehyde, benzene, xylene, and toluene through their leaves and roots. The plants then break down these pollutants into harmless substances or store them in their tissues.

9.2 Increasing Humidity

Calatheas also help increase indoor humidity levels, which can be especially beneficial during dry winter months. Plants release water vapor into the air through transpiration, which can help alleviate dry skin, coughs, and sore throats.

9.3 Improving Overall Well-being

In addition to their air-purifying and humidity-boosting benefits, Calatheas can also improve overall well-being by reducing stress and promoting relaxation. Studies have shown that being around plants can lower blood pressure, heart rate, and cortisol levels, and it can also increase feelings of happiness and contentment.
