The amniotes are distinguished from amphibians by the presence of a terrestrially adapted egg protected by amniotic membranes. The embryos of amniotes could develop within an aquatic environment inside the egg. This led to less dependence on a water environment for development and allowed the amniotes to invade drier areas
What key adaptations allowed amniotic to invade all terrestrial environments? Explain
explain how the amniotic egg enabled animals to venture further on terrestrial habitats and away from water, also comment on the advantages involved that enabled for a faster growing enbryo within the amniotic egg. (Zoology)
What roles do microorganisms play in terrestrial environments? (5 marks)
what adaptations do non-vascular plants share with vascular plants that allow for a terrestrial existence?
Xerophytes are plants that are able to grow in arid environments. Explain how the following adaptations of xerophytes would recuce traspiration rates and enhance these plants' survival in arid regions: thick cuticle, sunken stomata (stomata are found in cavities), leaf surface covered with dense mat of trichomes.
What were the important adaptations that allowed plants to inhabit land?
Within the taxon Tetrapoda groups like mammals, birds, crocodiles and snakes (= Amniota) are truly terrestrial: They are much less dependent water than amphibians. Which four adaptations are critical for this way of life and how are they adaptive (e.g. what is the advantage compared to an amphibian)? List four key adaptations and briefly explain (less than 80 words). a) b) c) d)
What key features help the terrestrial animals survive and reproduce on land? How?
What key features characterised the first land plants, allowing them to survive in a terrestrial environment? In what order (first to last) did seeds, vascular tissue, stomata and carpels evolve in early land plants?
Explain and gace examples about what kind of adaptations protists have that impart stiffness and protection.
