Photoautotrophs are organisms, typically a plant, that obtains energy from the sun to be able to convert inorganic materials to organic materials for cellular functions to take place such as biosynthesis and respiration. Its function is increased by the presence of the three types of pigments namely chlorophyll A and B and carotenoids because these are "enablers" of photosynthesis.
The chlorophyll serves as the stepping stone for the sunlight "energy-capture" . This pigment contains porphyrin ring through which electrons can freely to move. Since they move freely, the ring has the ability to gain or lose electrons easily thus they also have the ability to provide energized electrons to other molecules.
However, the carotenoids are accessory pigments only because they cannot directly transfer the energy from the sun to the photosynthetic pathway which means that the absorbed energy must be passed on to chlorophyll first.
Answer:
The rise in the level of water indicates that CO2 is produced by germinating seeds during respiration. Actually, the germinating seeds respire and produce CO2.
D. It performs all functions for the organism.
This is the correct answer! Hope that helps!

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
