Survival
The photosynthetic process that occurs in this species roots has the potential to supply oxygen to the rest of the plant while facing a flooded habitat. The cortical cells of the aquatic and semi aquatic roots contain photosynthetic chloroplasts. These chloroplasts produce specific responses to variation in carbon dioxide and light availability under water. They also contain proteins involved in the photosynthetic production of oxygen and carbon fixation. Unlike the sedimentary roots in this species, the aquatic roots get access to oxygen from the water column and can produce it internally. When both the semi aquatic and aquatic roots are submerged in water, photosynthesis occurs supplying oxygen for the plant.

Famous quotes containing the word survival:
“...I have a duty to speak the truth as I see it and to share not just my triumphs, not just the things that felt good, but the pain, the intense, often unmitigating pain. It is important to share how I know survival is survival and not just a walk through the rain.”
—Audre Lorde (1934–1992)
“However great a man’s fear of life, suicide remains the courageous act, the clear-headed act of a mathematician. The suicide has judged by the laws of chance—so many odds against one that to live will be more miserable than to die. His sense of mathematics is greater than his sense of survival. But think how a sense of survival must clamour to be heard at the last moment, what excuses it must present of a totally unscientific nature.”
—Graham Greene (1904–1991)
“Perhaps catastrophe is the natural human environment, and even though we spend a good deal of energy trying to get away from it, we are programmed for survival amid catastrophe.”
—Germaine Greer (b. 1939)
