Chloroplasts and Mitochondria

Explanation:
Detailed explanation-1: -The theory of how mitochondria, chloroplasts and other membrane-bound organelles in eukaryotic cell likely arose from a symbiosis between aerobic prokaryotes and host anaerobic eukaryotic ancestors.
Detailed explanation-2: -The first endosymbiotic event occurred when a eukaryotic cell engulfed a prokaryote (SF Fig. 2.4 Step 3). This process, known as primary endosymbiosis, created the mitochondrion. Chloroplasts likely evolved when a eukaryotic cell containing mitochondria engulfed a photosynthetic cyanobacteria cell (SF Fig.
Detailed explanation-3: -The endosymbiotic theory posits that some eukaryotic cell organelles, such as mitochondria and plastids, evolved from free-living prokaryotes.
