Ff

• Green Algae


  • Contain chlorophyll b
  • Some reproduce sexually
  • Live in fresh water
  • Live in symbiotic relationships
• Decomposers


  • Break down dead organisms
• Comycetes


  Water molds, possible cause of Irish Potato Famine
• Myxomycetes


  Mass of cytoplasm with many nuclei, during dry forms a stalk with haploid spore filled capsule
• Blo3P are plant-like protists
• Phytoplankton


  • Uni- and multi-cellular species
  • Called Algae
  • Photoautotrophic
  • Contain chlorophyll in chloroplast
  • Eaten by zooplankton
• Red Algae


  • Have no flagella
  • Cause the red tide which is toxic
  • Some are glow
• Diatoms


  • Used in diatomaceous earth, toothpaste, and reflective highway paint
  • Can become heterotrophic in the absence of light
• Brown Algae


  • Multicellular
  • Used in salad, toothpaste, and as a thickener in ice cream
• Volvo


  Group together in a shared sphere, but not truly multicellular
• Digestion of carbohydrates


  A process that begins in the mouth with salivary amylase released during chewing
• Digestion of carbohydrates


  1. Intake at the mouth

  2. Elimination from colon
• Types of carbohydrates found in the diet

  • Lactose from cheese
  • Sucrose, glucose, fructose from sugars in tomatoes
  • Starch in flour for crust
  • Fiber in flour, tomatoes, and others
• Mouth or oral cavity

  • Mechanical digestion to break large bites into smaller pieces and mix with saliva
  • Some enzymatic digestion of starch occurs due to salivary amylase
  • Salivary amylase breaks long glucose chains of starch into shorter chains like maltose
  • Other carbohydrates don't undergo enzymatic digestion in the mouth
• Stomach


  • Low pH inactivates salivary amylase
  • More mechanical digestion, little chemical digestion of carbohydrates
• Small intestine


  • Most carbohydrate digestion occurs here
  • Pancreatic amylase enzyme secreted from pancreas breaks starch down to oligosaccharides and maltose
• Starch digestion in small intestine

  1. Starch (amylose)

  2. Pancreatic amylase

  3. Oligosaccharide + Maltose
