Answer:
The endosymbiotic event that brought chloroplast in eukaryotic cells happened after the lineage delivered.
Explanation:
The endosymbiotic theory says that the ancestral cell gains the ability of photosynthesis when it engulfed a photosynthetic bacteria and this bacteria remained in a symbiotic relationship with the ancestral cell and evolved as chloroplast in plants that can perform photosynthesis.
All the eukaryotes do not have this internal structure like chloroplast because this endosymbiotic event must be happened after the divergence of the lineage into different groups. Therefore plant cells have chloroplast and animals cell do not have.
