Answer:
Prokaryotes are smaller and less developed compared to eukaryotes. Some of them inhabit very primitive environments that resemble earth’s early stages. Endosymbiotic theory states that eukaryotes arose by the endosymbiosis of prokaryotes.
Explanation
By endosymbiont theory, eukaryotic cells arise from prokaryotic cells. Here, the theory shows that eukaryotic ancestors lived in close association with prokaryotes, wherein in some cases, prokaryotes have been engulfed and might have lived inside eukaryotes.
Upon being engulfed by a host cell as undigested prey, these prokaryotes could have been internal parasites of the eukaryotes. But, later on, their relationship becomes mutualistic and these prokaryotes become incorporated as organelles, such as in the case of chloroplasts and mitochondria, which were previously separate prokaryotes

A white blood cell engulfing foreign materials is more likely to carry out Endocytosis.
Explanation:
- Endocytosis is the process by which a cell takes up a macromolecule into is cytoplasm by forming a vessicle.
- In the question two cases are given, both the cases involve the formation of membrane bound vessicle but in different ways.
- The excretion of hormones involves the movement of molecule outside the cytoplasm. This process is exocytosis.
- The engulfment of an antigen by WBC involves taking up of molecule within the cell so that it can be killed and digested. Thus in this case Endocytosis is more likely to occur..
