  1. Adaptations in Organisms

  2. Transport and Excretion • What is it? • You breath in oxygen, but how does it get throughout your body? • How does water get throughout your body? • What if you need to take in salt or remove it?

  3. Respiration • Exchange of gases

  4. Nutrition • Feeding adaptations • Autotrophic vs heterotrophic

  5. Reproduction growth and development • Sexual vs asexual • Internal fertilization vs external fertilization • Eggs, sperm, spores, seeds • Placental vs non placental

  6. Single Cellular Organisms Bacteria and Protists

  7. Transport and Excretion • How they get what they need to cells and how they move waste from cells of organs of excretion • Diffusion

  8. Gas Exchange • Some protists and bacteria use photosynthesis, some use respiration and some use both • Protist Video

  9. Nutrition • Heterotrophic, autotrophic or both?

  10. Reproduction, Growth and Development • Bacteria: Can they have sex? • Conjugation • binary fission • Protists: Mostly asexual

  11. Fungi

  12. Transport • They absorb nutrients from dead organisms and decaying organic matter and it diffuses throughout their mycelium (parts that make up their body)

  13. Gas exchange • They go through aerobic or sometimes anaerobic respiration

  14. Nutrition • They are heterotrophic and eat decaying organic matter (such as horse poop)

  15. Reproduction, Growth and Development • Fungi can sometimes reproduce sexually with spores and sometimes asexually • Asexually budding or fragmentation • yeast budding

  16. Plants • Bill Nye The Science Guy Plants

  17. Non-Vascular Plants mosses

  18. How do they get what they need? • Transport and excretion: Diffusion • Gas exchange: through diffusion • Nutrition: Photosynthesis • Reproduction, growth and development: sexually by sperm and eggs

  19. Vascular Plants

  20. Transport and excretion • Transpiration

  21. Gas Exchange

  22. Nutrition

  23. Reproduction • Seeds or spores depending on type of plant • Flowering plants

  24. Pollination

  25. Adaptations in Animals

  26. Sponges

  27. Sponges • Transport and excretion: Diffusion • Gas exchange: Respiration • Nutrition: Filter feeders • Reproduction: Sexual • sponges

  28. Cnidarians

  29. Cnidarians • Transport and excretion: Diffusion • Respiration: Aerobic respiration • Digestion: Use nematocysts for digestion • Reproduction: Asexual or sexual • Nematocyst • Box Jelly

  30. Flatworms

  31. Flatworms • Transport and excretion: Digestive tract (finally!) • Respiration: Aerobic respiration • Nutrition: Mouth and digestive tract (but only one opening!!!) • Reproduction Growth and Development: Sexual reproduction externally • Flatworm sex • tapeworm

  32. MollusksOctopus

  33. Transport and excretion • Transport and excretion: closed circulatory system for transport and nephridia for excretion

  34. Mollusks • Respiration: Gills or lungs (depending if on land or in water) • Nutrition: Filter feeder or through mouth (radula) • Reproduction: Sexually externally

  35. Segmented worms

  36. Transport and Excretion • Closed circulatory system, digestive system and anus

  37. Segmented Worms • Respiration: Skin • Nutrition: Mouth and anus • Reproduction: Sexually using eggs and sperm • Annelids

  38. Arthropods Insects, crustaceans and arachnids

  39. Transport and excretion • Open circulatory system (they are small) • Digestive system and anus • What is their outer skeleton called?

  40. Respiration • Tracheal tubes, spiracles, book lungs or gills in underwater crustaceans

  41. Nutrition • Mouthparts specialized for eating

  42. Reproduction • Sexually internally or externally • Praying Mantis male gets eaten • Barnacle
