GCSE Biology - Transport in plants - Translocation (Phloem) and Transpiration (Xylem) #51

Cognito4 minutes read

Plants transport sugars through translocation in phloem cells and water through xylem tubes. Transpiration, driven by evaporation, moves water and mineral ions from roots to leaves, influenced by factors like light intensity and humidity.

Insights

  • Phloem cells form tubes with pores to transport sugars in plants, while xylem tubes move water and minerals from roots to leaves via evaporation, highlighting the intricate mechanisms of nutrient distribution within plants.
  • The rate of transpiration in plants is influenced by various factors like light intensity, temperature, air flow, and humidity, showcasing the complex interplay of environmental conditions on the physiological processes of plants.
