REVISION NOTES
IGCSE Edexcel Biology
2.10 Transport (in Plants)
2.10.1 Understand why simple, unicellular organisms can rely on diffusion for movement of substances in and out of the cell
2.10.2 Understand the need for a transport system in multicellular organisms
2.10.3 Describe the role of phloem in transporting sucrose and amino acids between the leaves and other parts of the plant
2.10.4 Describe the role of xylem in transporting water and mineral ions from the roots to other parts of the plant
2.10.5B Understand how water is absorbed by root hair cells
2.10.6B Understand that transpiration is the evaporation of water from the surface of a plant
2.10.7B Understand how the rate of transpiration is affected by changes in humidity, wind speed, temperature and light intensity
2.10.8B Practical: investigate the role of environmental factors in determining the rate of transpiration from a leafy shoot
