Plants

• Photosynthesis:word equation


  Carbon dioxide+water>glucose+oxygen
• Photosynthesis:chemical equation


  6Co2+6H2O > C6H12O6+6O2
• Uses of glucose in plants

  -stored as starch

  -stored as fats+oils

  -used as energy

  -used for cellulose

  -proteins for plant growth
• Deficiency signs in plants


  Nitrates-small plants(studded growth)-weak

  Mg-magnesium-yellow leaves (bottom upwards)

  K-potassium-poor growth,yellow leaves, black spots

  Phosphates- poor root growth, purple leaves
• Deficiency signs in plants solutions 


  Nitrates-protein needed for growth

  Mg-more chlorophyll

  K-

  P-
• what does the phloem transport 


  products produced by photosynthesis- sugars+amino acids.
• What direction does the phloem flow

  upwards + downwards
• what is the phloem needed for

  growing plants

  developing seeds

  storage
• Does the phloem require energy

  Yes it requires energy
• what does the xylem transport

  water+minerals from roots to part of plants (leaves)
• what direction does the xylem flow

  upwards
• Does the xylem require energy

  No energy required
• What is lignin (xylem)


  dead hollow tissue- form system of pipes
• what is diffusion 


  movement of moleclues from high to low concentration
• what is active transport 


  move molecules against concentration gradient from low to high concentration
• what is osmosis 


  diffusion of water molecules from high to low concentration

  -through partially permeable membrane
