• What is the first step of water transplantation in plants?

  Water osmoses into root hair cells which are specialised snd have projections creating a large surface area
• what is the second step?

  water then moves into the root cortex cells
• what is the third step?

  xylem vessels collect water from the root cortex and transport it up the plants stem
• what is the last step?

  when it reaches a leaf water osmoses out of the xylem into the leafs mesophyll cells
• what is translocation


  translocation is the process by which food produced in photosynthesis is transported from the leaves to the growing regions of plants and storage organs
• what are the features of translocation?

  Translocation happens through phloem tubes which are made up of columns of walls of elongated cells that have holes in the end which allows cell sap that stores sugars salts and amino acids to pass between cells
• Unlike water transport what is translocation?

  It is bidirectional meaning movement is both up and down the plant
• How is glucose transported to the cells?

  in the blood plasma
• How is carbon dioxide removed from your body?

  it is transported to the lungs in the blood plasma where it is exhaled
• What are two applications of fermentation?

  to produce alcohol and to allow bread to rise
• What is the word equation for fermentation?

  Glucose  ethanol + carbon dioxide
• Which product of fermentation allows bread to rise?

  carbon dioxide
• What is the role of fertilisers?

  to provide the plants with enough minerals to prevent mineral deficiency
• What mineral deficiency leaves purple younger looking leaves?

  phosphorous
