Answer:
The eukaryotic cell were able to capture sunlight and produce energy(sugar) through photosynthesis.
Explanation:
According to the endosymbiotic theory a larger cell engulfed a smaller bacteria which can do photosynthesis and helped in the evolution of the eukaryotic cell. This evidence is seen in plant cells where chloroplast is present which shows similarities with prokaryotes.
The photosynthetic bacteria benefitted eukaryotic cells because the eukaryotic cell gained the ability to capture light energy and using light energy for the formation of energy molecules which is sugar and this process is called photosynthesis.
