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.
