Plant Organisation

• Small intestine absorbs food from the gut wall into our blood.
• The stomach churn the food molecules and kills harmful bacteria.
• Our oesophagus connects our mouth to our stomach.
• Undigested food leaves the body through our rectum as faceas.
• Our liver produces bile which breaks down fats.
• The pancreas produces digestive enzymes.
• Enzymes speed up digestion.
• amylase and other carbohydrase enzymes break down carbohydrates into sugar e.g. starch into glucose.
• protease enzymes break down proteins into amino acids.
• lipase enzymes break down lipids (fats and oils) into fatty acids and glycerol.
• The Small Intestine is covered with lots of Villi.
• Villi is good for absorption as they have a thin outer layer of cells, a good blood supply and a large surface area.
• The upper epidermis is thin to allow light to penetrate.
• The upper epidermis covers and protects the leaf.
• The stomata are holes in the more epidermis that enable gas exchange.
• The guard cells controls the size of the stomata and open and closes the stomata.
• The palisade mesophyll has lots of chloroplasts for photosynthesis to take place.
• The spongy mesophyll is where gas exchange takes place through diffusion due to the big air spaces.
• The waxy cuticle waterproofs the leaves and minimises water loss.
• What does phloem transport? 


  dissolved sugars (glucose)
• What does xylem transport?


  water and mineral ions
• What is translocation?


  The process by which plants transport dissolved substances
• What is transpiration? 


  The loss of water from the plant‘s leaves?
