Which statements correctly connect spongy mesophyll structure with gas movement through a leaf? Select all that apply.
Gaps between cells create internal routes for gases.✓Bonne réponse
The cells form a solid layer with no spaces.
Air spaces allow diffusion through the leaf interior.✓Bonne réponse
Impermeable plugs prevent gases entering the spaces.
Explication
Spaces between spongy mesophyll cells form internal routes through which gases can diffuse across the leaf. Packing the cells with no gaps or sealing those routes would reduce rather than support internal gas movement.
