Question: Explain how a symbiotic relationship like the one described in the endosymbiotic theory would have benefited each cell.

The endosymbiotic theory suggests that eukaryotic cells evolved through a mutually beneficial relationship between two different types of cells, where one was engulfed by the other. Here's how this relationship would have benefited each cell:

1. Host Cell's Benefit: 

   - The engulfed cell, likely an early prokaryote capable of performing aerobic respiration (like the precursor to mitochondria), provided the host cell with efficient energy production. This energy advantage allowed the host cell to thrive in environments where energy demands were higher.

   - In the case of photosynthetic bacteria (precursors to chloroplasts), the host cell gained the ability to harness sunlight for energy through photosynthesis.

2. Engulfed Cell's Benefit:

   - The smaller cell found protection within the larger host cell, shielding it from external threats and harsh environmental conditions.

   - It also received access to nutrients from the host cell, ensuring a stable supply for its metabolic needs.

This symbiotic relationship allowed both cells to work together and evolve into the complex eukaryotic cells we see today.
