Adaptations in Organisms. 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?. Respiration. Exchange of gases . Nutrition. Feeding adaptations
E N D
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?
Respiration • Exchange of gases
Nutrition • Feeding adaptations • Autotrophic vs heterotrophic
Reproduction growth and development • Sexual vs asexual • Internal fertilization vs external fertilization • Eggs, sperm, spores, seeds • Placental vs non placental
Single Cellular Organisms Bacteria and Protists
Transport and Excretion • How they get what they need to cells and how they move waste from cells of organs of excretion • Diffusion
Gas Exchange • Some protists and bacteria use photosynthesis, some use respiration and some use both • Protist Video
Nutrition • Heterotrophic, autotrophic or both?
Reproduction, Growth and Development • Bacteria: Can they have sex? • Conjugation • binary fission • Protists: Mostly asexual
Transport • They absorb nutrients from dead organisms and decaying organic matter and it diffuses throughout their mycelium (parts that make up their body)
Gas exchange • They go through aerobic or sometimes anaerobic respiration
Nutrition • They are heterotrophic and eat decaying organic matter (such as horse poop)
Reproduction, Growth and Development • Fungi can sometimes reproduce sexually with spores and sometimes asexually • Asexually budding or fragmentation • yeast budding
Plants • Bill Nye The Science Guy Plants
Non-Vascular Plants mosses
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
Transport and excretion • Transpiration
Reproduction • Seeds or spores depending on type of plant • Flowering plants
Sponges • Transport and excretion: Diffusion • Gas exchange: Respiration • Nutrition: Filter feeders • Reproduction: Sexual • sponges
Cnidarians • Transport and excretion: Diffusion • Respiration: Aerobic respiration • Digestion: Use nematocysts for digestion • Reproduction: Asexual or sexual • Nematocyst • Box Jelly
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
Transport and excretion • Transport and excretion: closed circulatory system for transport and nephridia for excretion
Mollusks • Respiration: Gills or lungs (depending if on land or in water) • Nutrition: Filter feeder or through mouth (radula) • Reproduction: Sexually externally
Transport and Excretion • Closed circulatory system, digestive system and anus
Segmented Worms • Respiration: Skin • Nutrition: Mouth and anus • Reproduction: Sexually using eggs and sperm • Annelids
Arthropods Insects, crustaceans and arachnids
Transport and excretion • Open circulatory system (they are small) • Digestive system and anus • What is their outer skeleton called?
Respiration • Tracheal tubes, spiracles, book lungs or gills in underwater crustaceans
Nutrition • Mouthparts specialized for eating
Reproduction • Sexually internally or externally • Praying Mantis male gets eaten • Barnacle
