Slide1
Respiration, Nutrition, Excretion, & Movement
Structural Adaptations
of
OrganismsSlide2
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?Slide3Slide4
Fish RespirationSlide5
Amphibian RespirationSlide6
Reptile, Bird, & Mammal RespirationSlide7
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 materials
Accomplished
in various ways:
Examples:
Exocytosis
(
protists
/plankton)
Filter feeders
(sponges, mollusks)
Excretory system(animals)Slide8
Nutrition & Excretion of
ProtistsSlide9
Nutrition & Excretion in
filter feedersSlide10
Nutrition & Excretion in animalsSlide11
Structure matches environmental needs
Examples:
Cilia/flagella/Pseudopods(single-celled organisms)Fins(fish, aquatic mammals)Feathers/hollow bones(birds)Tetrapods(amphibians, reptiles, mammals)
How do organisms move?Slide12
Single-celled movementSlide13
Fish movementSlide14
Bird movement
Hollow bones
Retractable FeathersSlide15
Adaptations of Flight
Human Arm
Bird Wing
Bat WingSlide16
Tetrapod movement examples:
Cheetah
Orangutan
GroundhogSlide17
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 up
Phloem
- moves nutrients up and down
What about Plants?Slide18
