Structural Adaptations Multicellular

Plant Adaptations Nonvascular vs Vascular Plant structure Xylem vs. Phloem Gymnosperm Vs. Angiosperm Plant structure Stamen vs carpel Sepal vs leaves Petals Receptacle vs stem Stomata on leaves

Animal Adaptations Invertebrates Vertebrates No backbone 95% of all animal species Examples: sponges, worms, arthropods (insects, crabs), etc. Vertebrates Has backbone Examples: cartilaginous fish (sharks), bony fish, amphibians, reptiles, birds, and mammals

Animal Adaptations Ectothermic Endothermic Cold blooded animals Reflects outside temperature Endothermic Warm blooded animals Body maintains a certain temperature

Animal Adaptations Gills Lungs External – gets oxygen from surrounding water Lungs Internal – breathes oxygen from air

Animal Adaptations 2 chambered heart 3 chambered heart Use gills to replenish Oxygen in blood supply 1 flow route for blood Ex. fish 3 chambered heart Contains lungs for respiration More blood flow Ex. Amphibians and reptiles Amphibians can also breathe through their skin 4 chambered heart Most efficient for life on land Ex. Birds and mammals

Animal Adaptations Internal Fertilization External Fertilization Union of gametes inside the body of a parent Ex. Mammals, arthropods, etc. External Fertilization Union of gametes outside the body of a parent Ex. Fish, amphibians, etc.
