Food
Digestive system
Oesophagus (Peristalsis)
Stomach (Hydrochloric acid Protease -->Protein
Mouth (Amylase carbohydrates --> sugars)
Small intestine (Pancreas adds energy)
Rectum (stores poo)
Large intestine (Absorbs water)
Anus waste go bye bye
Food test's
Simple sugar
Benedict's solution (blue --> orange)
Starch
Iodine (brown/yellow --> Black)
Protein
Buiret (blue --> purple)
Lipids
Rub on paper (Clear)
Types of feeders
Herbivore
Omnivore
Carnivore
Produces Plants
Food groups
Protein Growth and repair
Lipids (fats) Energy
Complex carbohydrates (starch) Long Energy
Simple Carbohydrates (sugar) Fast energy
Leaf adaptations
chloroplasts
Top layer of leaf where photosynthesises occurs
Stomata
CO2 in O2
Guard cells
spongy cells
Allows gas exchange
Photosynthesise
CO2 +H2O = sugar and O2
Stores sugar as starch
Leaf test
Soften in hot water
spread out on petri dish
place leaf in hot ethanol for 5 min (Remove Green)
Place iodine starch test (brown/yellow --> black)
Boil leaf in water for 5 min (softens cells)
Digestion/Absorption
HCI
Protein = Amino acids
Carbohydrates = sugar
Fats = Glycerol & Fatty acids
Villi lining of the intestines which increase the surface area for absorption
