Black flora gas exchange is comparable to the gas exchange that occurs in plants on Earth, with CO2 being fixed from the atmosphere to provide building blocks for sugars and other material and oxygen being released during photosynthesis from the splitting of water molecules. They do use oxygen itself for aerobic respiration in all their tissues, and as such do need access to the gas even in parts that do not perform photosynthesis. The many kinds of black flora on Sagan 4 employ various means of bringing both CO2 for fixation and oxygen for respiration into themselves, many of the smaller forms do it passively through their moist epidermis, others have forms of pores, lenticels, and even stomata. These entries into the flora may lead to spongy tissues directly or may lead to more complex tracheal systems depending on the species. |

As the product of photosynthesis in black flora is sugar their sap in its pure form is typically clear or yellow to amber. However when witnessed in the field more often than not the sap will be oozing from damages inflicted on chloroplast rich tissues, the dark pigments from said parts will change the sap coloration to something more smokey, or even brown or black depending on how severe. The color of liquid coming from a wound on a member of the black flora kingdom may also depend on other substances in their tissues, not strictly sap or chloroplast, and so could be any range of tints or hues depending on what the compounds may be within them. |
