Stroma vs. Stomata: Know the Difference
By Shumaila Saeed || Published on January 26, 2024
Stroma is the supportive tissue of an organ, while stomata are microscopic openings on plant leaves for gas exchange.
Key Differences
Stroma refers to the supportive framework of an organ, consisting of connective tissue and blood vessels. In contrast, stomata are small openings or pores found primarily on the underside of plant leaves, playing a crucial role in gas exchange.

In the context of a plant's leaf, the stroma is found within the chloroplasts, serving as the site of the light-independent reactions of photosynthesis. Stomata, on the other hand, facilitate the exchange of gases like oxygen and carbon dioxide between the plant and its environment.

The stroma in human or animal tissues provides structural support and is often involved in immune responses. Meanwhile, stomata regulate water loss through transpiration and are essential for maintaining the plant's water balance.

Stroma can be found in various organs, including the ovaries, lymph nodes, and the eye's cornea, where it provides both structural and functional support. In contrast, stomata are specific to plants and are integral to the process of photosynthesis by allowing carbon dioxide to enter the leaf.

The density and distribution of stroma vary depending on the organ and its function. Conversely, the distribution and density of stomata on a leaf surface are influenced by environmental factors like light, humidity, and temperature.
