Detailed explanation-1: -The host animal serves as a protected environment, providing the alga with a constant supply of nutrients in the form of nitrogen, phosphorus, and sulfur. In turn, the alga provides the host with glucose.
Detailed explanation-2: -There are two major organelles in eukaryotic organisms that have resulted from endosymbiosis, mitochondria (common to most eukaryotes) and chloroplasts (found in plants and algae only), as well as a few less obvious examples.
Detailed explanation-3: -The prokaryotic cells that live inside eukaryotic cells are called endosymbionts. Endosymbiosis is a term used to describe two organisms living together with one inside the other. The word endosymbiont comes from two Greek root words: endo, meaning within, and symbios meaning, living together.
