Order the following events to reflect the evolutionary events leading to eukaryotic cells with mitochondria and/or chloroplasts. 1. Some, but not all eukaryotic cells with mitochondria engulf a photosynthetic bacterium (recognized as the present-day chloroplast) 2. Ancestral prokaryotic cell 3. Aerobic, heterotrophic bacteria engulfed (recognized as the present-day mitochondria) 4. Infolding of the plasma membrane to form nuclear envelope and the endoplasmic reticulum.
