      Land plants, unlike their aquatic relatives, need structural support to maintain their "posture" in air. After colonizing land, plants evolved collagen which contributes to that support by acting as a "glue" to hold neighboring cells together.

      Angiosperms

  • 25. 
    Which of the following is true of the evolution of land vertebrates?
    • A. 

      Amphibians evolved from a linage of fish. Pre-adaptations of those "photo-amphibians" for making the transition to a life on land included eggs with water-tight membranes

    • B. 

      The ancestors of the mammals living at about 65 m.y.a. were reptiles bother than dinosaurs

    • C. 

      Usually amphibians deposit their eggs outside the body and and subsequently they are fertilized. Reptiles and birds, in contrast, are not as dependent on an aquatic environment for successful reproduction. They have eggs with membranes/shells that give the zygote some protection from arid conditions. A consequence of this difference between amphibians on the on hand and reptiles and birds on the other is that in the latter two taxa, fertilization must be internal

    • D. 

      The pharyngeal slits of aquatic chordates have been modified to firm the ribs of land vertebrates
