GENERAL KNOWLEDGE

Detailed explanation-1: -Scientists have discovered how plants create networks of air channels – the lungs of the leaf – to transport carbon dioxide (CO2) to their cells. Botanists have known since the 19th century that leaves have pores – called stomata – and contain an intricate internal network of air channels.

Detailed explanation-2: -Trees act like the lungs of the earth. Trees help the planet breathe by turning carbon dioxide into clean, pure oxygen. Trees and forests around the world also act like the planet’s air conditioning system and keep the planet cool.

Detailed explanation-3: -Okay so this the correct answer for the question is that the human lung and plant leaf, they are similar because both organs exchange oxygen and carbon dioxide exchange oxygen and carbon dioxide.

Detailed explanation-4: -A leaf is a principal appendage of the stem of a vascular plant, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in “autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system.
