Questions and Answers

What are the two important forces responsible for the uptake of water and minerals in plants?

The two important forces responsible for the uptake of water and minerals in plants are absorption and transpiration.

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.
