Question

according to endosymbiotic theory, how did eukaryotes acquire photosynthetic capabilities? engulfing a fungal cell engulfing a photosynthetic prokaryote engulfing a heterotrophic cell

Explanation:

The endosymbiotic theory states that eukaryotes acquired organelles like chloroplasts (for photosynthesis) by engulfing photosynthetic prokaryotes (like cyanobacteria) that then lived symbiotically. Fungal cells are not photosynthetic in a way that would directly give photosynthetic capabilities, and heterotrophic cells don't perform photosynthesis. So the correct option is the one about engulfing a photosynthetic prokaryote.

Answer:

B. engulfing a photosynthetic prokaryote (assuming the options are labeled A, B, C with A: engulfing a fungal cell, B: engulfing a photosynthetic prokaryote, C: engulfing a heterotrophic cell)
