Study Notes

Plant Structure and Function

  • Plants absorb water from soil and carbon dioxide from the atmosphere.
  • Sunlight and chlorophyll in leaves are essential for photosynthesis.
  • Food (glucose) is produced in leaves and transported to other parts of the plant via the phloem.
  • Xylem transports water and minerals from roots to stems and leaves.

Activity 1: Water Conduction

  • Aim: Demonstrate water transport in plants.
  • Materials: Beaker, water, plant, eosin dye.
  • Procedure: Uproot a plant, wash roots, submerge in eosin solution, and leave for 3-4 hours.
  • Observation: Eosin (red dye) travels from roots to leaves, particularly through the mid-vein and side veins.
  • Conclusion: Xylem forms a continuous network, transporting water from roots to leaves.

Water Absorption by Root Hair

  • Root hairs absorb water from the soil.
  • Water and mineral salts are transported via the xylem.
  • Ascent of sap is the movement of water and minerals from roots to leaves.
  • Two forces drive uptake: from roots and leaves.

Xylem Function

  • Xylem transports water and minerals.
  • It does this through a system of tubes (vascular tissue) throughout the plant.
  • Ascent of sap is facilitated by forces originating from roots and/or leaves (e.g., absorption pressure & transpiration pull).

Tissues and Organs

  • Tissues are groups of similar cells performing special functions.
  • Xylem and phloem are plant tissues.
  • Connective and muscular tissue are animal tissues, forming organs.
