The answer indeed has to do with similarities between genes coding for proteins involved in adherence and attachment in choanoflagellates and animals. Let me explin it to you a little further. Choanoflagellates are a group of protists. There is Morphological Evidence that can explain how close these protists are as closing living relatives to animals. Not only is morphological evidence the ones that help to conclude that but also molcular evidence. The choanoflagellates are a group of <span>of free-living unicellular and colonial flagellate eukaryotes. </span>
Answer:
Photosynthetic lamellae
Explanation:
The cyanobacteria were the first successful photosynthetic cells present on the Earth which were able to convert the light energy into the chemical energy.
The endosymbiosis theory suggested that these cyanobacteria were engulfed by the eukaryotes and the cyanobacteria get transformed into the chloroplast.
The region of the chloroplast that was formed in the cyanobacteria before the endosymbiosis happened was the photosynthetic lamellae which contained the chlorophyll molecule and thus is the correct answer.
Thus, Photosynthetic lamellae are the correct answer.
I believe the are recently new within the last 50 years i would imagine
I think the answer would be protons
