Respiration, Nutrition, Excretion, & Movement
Structural Adaptationsof
Organisms
The break down of glucose to create ATP energy for cells
Occurs in the mitochondriaAccomplished in various ways:
Ex.Single-celled organisms(diffusion)Insects(spiracles & tracheal trunk)Fish(gills)Amphibians(gills & lungs)Reptiles, birds, mammals(lungs)
What is Respiration?
Fish Respiration
Amphibian Respiration
Reptile, Bird, & Mammal Respiration
The absorption of materials for energy or structure
Accomplished in various ways:Examples:
Phagocytosis(protists/plankton)Filter feeders(sponges, mollusks)Digestive system(animals)
What is nutrition?
What is excretion?The removal of unused or unnecessary
materialsAccomplished in various ways:
Examples:Exocytosis(protists/plankton)Filter feeders(sponges, mollusks)Excretory system(animals)
Nutrition & Excretion of Protists
Nutrition & Excretion in filter feeders
Nutrition & Excretion in animals
Structure matches environmental needsExamples:
Cilia/flagella/Pseudopods(single-celled organisms)
Fins(fish, aquatic mammals)Feathers/hollow bones(birds)Tetrapods(amphibians, reptiles, mammals)
How do organisms move?
Single-celled movement
Fish movement
Bird movementHollow bones
Retractable Feathers
Adaptations of
Flight Human Arm
Bird Wing
Bat Wing
Tetrapod movement examples:
Cheetah
OrangutanGroundhog
Structures:1) Leaves
Carry out photosynthesis(make sugar)Release oxygen and absorb carbon dioxideRelease excess water(stomata)
2) RootsAbsorb nutrients(nitrates, phosphates) and waterAnchor the plant
3) StemsSupport branches and leavesTransports materials
Xylem- carries water upPhloem- moves nutrients up and down
What about Plants?
