Exchange of Gases in Plants
Pay Attention・2 minutes read
Plants exchange gases like carbon dioxide and oxygen through various parts via diffusion, with intercellular gas exchange in leaves occurring in air spaces between spongy mesophyll. Respiration happens day and night, so caution is advised against sleeping under a tree at night due to increased CO2 release.
Insights
- Intercellular gas exchange in leaves primarily occurs in air spaces between spongy mesophyll, where oxygen from photosynthesis is utilized and carbon dioxide is produced. This process highlights the continuous nature of respiration, contrasting with sunlight-dependent photosynthesis.
- Gas exchange in plants is facilitated not only by leaves but also by stems and roots, utilizing specialized cells like Lenti cells in woody stems and moist membranes of root hairs and epidermal cells. This multifaceted system ensures efficient exchange of gases crucial for plant survival and growth.

Plant Gas Exchange: Roots, Stems, Leaves, Photosynthesis
- Plants exchange gases through various parts like roots, stems, and leaves via diffusion, with carbon dioxide and oxygen being exchanged. Intercellular gas exchange in leaves happens in air spaces between spongy mesophyll, utilizing oxygen from photosynthesis and producing carbon dioxide for photosynthesis. While photosynthesis only occurs during sunlight, respiration happens day and night, cautioning against sleeping under a tree at night due to increased CO2 release. Gas exchange also occurs in stems and roots, facilitated by Lenti cells in woody stems and moist membranes of root hairs and epidermal cells.
