ICSE Class 10 Biology / Absorption by Roots – The process Involved 1- Characteristics of Roots
Best for NEET・2 minutes read
Roots are vital for plants by fixing them to the soil, absorbing water and minerals, conducting nutrients, and providing mechanical support. Water and minerals absorbed by roots are essential for plant functions such as photosynthesis, transpiration, and nutrient transportation, with factors like surface area, root hairs, cell sap concentration, and thin root cell walls influencing water absorption.
Insights
- Roots are vital for plants as they anchor them in the soil, absorb water and minerals, transport nutrients, and provide structural support to plant cells.
- Factors such as root hairs, surface area, cell sap concentration, and thin cell walls significantly impact the root's ability to absorb water efficiently, with root hairs playing a crucial role by facilitating water movement through the cell membrane.
