Answer:
The sequence will be:
4. Origin of cyanobacteria
3. Origin of chloroplasts
2. Origin of multicellular eukaryotes
1. Origin of Chloroplasts
5. Origin of fungal/plant symbioses
Explanation:
1. origin of mitochondria : Mitochondria is thought to be originated more than more than 1.45 billion years ago.
2. origin of multicellular eukaryotes : They actually evolved from unicellular eukaryotes at least over 1.7 billion years ago
3. origin of chloroplasts : Its origin is traced to as far back as 600 to 2 billion years ago
4. origin of cyanobacteria : They originated about 2.45 - 2.22 billion years ago.
5. origin of fungal/plant symbioses: DNA sequence and fossil evidence suggests that they originated around 400-460 million years ago
