1. Life Processes in Living Things
Biology I

2. Transport
How does the organism move needed substances into & out of cells?
Plants
Xylem: moves water & minerals up
Phloem: moves food up & down
Diffusion, Osmosis, Endocytosis, Exocytosis
Cellular basis
Circulatory System
Move across large distances
Open vs. Closed

3. Transport – Cellular Level

4. Transport - Plants

5. Transport – Circulatory System

6. Excretion How does the organism removal waste from the body?
Diffusion: high  low (cell to cell)
Plants: transpiration (H2O & O2)
Protists: contractile vacuole, anal groove
Animals:
Diffusion
Malpighian Tubules (insects)
Kidneys

7. Excretion - Protist

8. Excretion - Mammals

9. Respiration How are O2 & CO2 exchanged? Transpiration (in plants)
Simple diffusion through moist surface
Skin
Trachae (insects)
Gills (aquatic organisms
Lungs (higher animals)

10. Respiration - Plants

11. Respiration - Animals

12. Regulation/Homeostasis
To maintain balance/equilibrium
Single-Celled Organism - diffusion
Multi-cellular Organisms
Nutrients – blood sugar
Wastes
Body Temp pH

13. Nutrition Process of getting nutrients into the cells of the body
Protists: endocytosis, oral groove, diffusion
Plants: roots, photosynthesis
Animals: digestive system, villi

14. Nutrition - Endocytosis

15. Nutrition

16. Reproduction Continuation of the species/offspring
Asexual: identical to parents
Binary Fission – bacteria and/or protists
Budding
Fragmentation
Sexual: variation from parents
External: sperm + egg meet outside the body
Must live in water
Internal: sperm + egg meet inside the body

17. Asexual – Binary Fission

18. Asexual - Budding

19. Asexual - Fragmentation

20. Sexual – creates variation
External Fertilization

21. Sexual
Internal Fertilization

22. Growth & Development Growth: increase in amount Development: changes
mitosis
Development: changes
Amniotic Egg –creates a boundary that allows the embryo to develop on land (w/o water)
Metamorphosis
Complete: egg  nymph  adult
Incomplete: egg  larva  pupa  adult
Butterflies, flies

23. Complete Metamorphosis

24. Incomplete Metamorphosis

25. Amniotic Egg
