a. Explain how the inner membrane system of a chloroplast makes it well adapted for photosynthesis.

b. Copy the table below and insert ticks or crosses to show which structural features are shared by a plant chloroplast and a typical prokaryotic cell.

✓= structural feature shared; ✗ = structural feature not shared.

Structural feature	Structural feature shared by chloroplast and typical prokaryotic cell
circular DNA
DNA combined with structural protein to form chromosomes
ribosomes about 18 nm in diameter
complex arrangement of internal membranes
peptidoglycan wall
size ranges overlap
