Detailed explanation-1: -Four major adaptations are found in all terrestrial plants: the alternation of generations, a sporangium in which the spores are formed, a gametangium that produces haploid cells, and apical meristem tissue in roots and shoots.

Detailed explanation-2: -Plants have evolved several adaptations to life on land, including embryo retention, a cuticle, stomata, and vascular tissue.

Detailed explanation-3: -One of the most significant events in the history of our planet, with tremendous repercussions for the evolution of earth’s organisms and ecosystems, was the colonization of terrestrial environments by plants ∼470 million years ago 1, 2, 3.

Detailed explanation-4: -There are three types of adaptation-structural adaptation, behavioural adaptation, and physiological adaptation.
