Question

any type of phototrophy involves: light - absorbing photoreceptors and a mechanism to link the photoreceptor process to energy storage. what is missing from this list that is also common to all types of phototrophy? a) the presence of chlorophyll b) oxygen as the terminal electron acceptor c) the presence of chloroplasts d) water as the supplier of electrons to the phototrophic system e) none of the above is correct

Explanation:

Phototrophy involves light - absorbing photoreceptors. Chloroplasts are essential organelles in photosynthetic organisms for the process related to phototrophy. Chlorophyll is present in chloroplasts and is involved in light - absorption. Oxygen is a product of some phototrophic processes and is a terminal electron acceptor in respiration related to energy storage. Water is the electron donor in oxygen - evolving phototrophy. The presence of chloroplasts is a key and common feature in many phototrophic systems.

Answer:

C. the presence of chloroplasts
