Osmotic Adjustment in Plants | Class 11 Biology Chapter 8 Plant Physiology (2025)

Описание: In this video, we explain Osmotic Adjustment in Plants according to Class 11 Biology New Book 2025, Chapter 8 (Plant Physiology). Osmotic adjustment is an important physiological mechanism that helps plants maintain water balance and cell turgidity under different environmental conditions. Plants adjust the osmotic potential of their cells by accumulating solutes such as sugars, salts, and organic compounds to survive stress conditions.
This lecture covers osmotic adjustment in different plant types, including Hydrophytes, Halophytes, and Mesophytes.
Hydrophytes grow in water-rich environments and usually have low osmotic pressure because water is easily available.
Halophytes are salt-tolerant plants that grow in saline soils; they maintain osmotic balance by accumulating salts and organic solutes in their cells.
Mesophytes grow in moderate environmental conditions and show normal osmotic regulation to maintain water absorption and cell function.
This topic is very important for board exams, conceptual understanding, and competitive exams. The lecture is explained in simple language with a focus on key biological terms and exam-oriented concepts.
