Answer;

b. Their ability to pass on genetic information.

Explanation;

-Protobionts are systems that are considered to have possibly been the precursors to prokaryotic cells. A protobiont is an aggregate of abiotically produced organic molecules surrounded by a membrane or a membrane-like structure.

-They exhibit some of the properties associated with life, including simple reproduction, metabolism and excitability, as well as the maintenance of an internal chemical environment different from that of their surroundings.

Zigmanuir [339]
The plant's production of high-energy sugars would reduce significantly. I'm not going to say that the plant would completely stop producing the sugars because it has to respire, and one product of respiration would be carbon dioxide. This carbon dioxide would be recycled so that the plant can photosynthesize and produce sugars.

What do anaerobic organisms have in common with photosynthetic organisms?
Dvinal [7]

Ans is option C. They both need an energy source in order to survive.

Energy is an absolute necessity to survive on this earth. All living organisms need energy be it anaerobic or photosynthetic.  Photosynthetic organisms can make their own food in the presence of sunlight by photosynthesis and harness energy from it. Anaerobic organisms can also make their own food in the absence of sunlight with the help of inorganic molecules like hydrogen sulfide (H2S), ammonia (NH3), sulphur (S) etc.

Its just that anaerobic organism's way of harnessing energy is different from those of aerobes/photosynthetic organisms but they need energy source for sure.
