Plant Water Relationship- Part I Physiological Role of water

Описание: Water is one of the most essential elements for the existence of life. Animals can move from one place to another in search of water, but what about plants? Plants complete their life cycle in the one place where they germinate and perpetuate. How the plants reach the source of water? how they absorb and transport water to each cell of their body?

This series of videos will help to understand how this happens.

In part-I, we will discuss the physiological role of water.
Water is inevitable for the existence of life.
Water is a major component of protoplasm.
Water is essential for germination.
Water takes part in growth through turgidity.
Water is the donor of electrons, protons, and oxygen during photosynthesis.
Water helps to breakdown complex food into simple on by hydrolysis of food.
Plants need water for the absorption of nutrients.
Water gives a cooling effect to the plant body through transpiration.
Water is a universal solvent.

Water is one of the most essential elements of life and plant. It is essential for physiological functions like photosynthesis, respiration, growth, transpiration, absorption of nutrients.
Water contributes about 70 to 85 % of the fresh weight of the plant body. Seeds are comparatively dry by they could germinate only after a supply of an adequate amount of water.

I hope, this will help to understand the concepts 'Why life is present only on planet earth? and why we are searching for the existence of water in space?'.

This video will be helpful for the students of Life Sciences specifically those studying Biology, Botany, Zoology, Microbiology, Biotechnology, Biochemistry, and Molecular Biology. It will also prove an important video for those who are preparing for competitive examinations MPSC, UPSC, Forestry, CSIR-NET, and SET/ SLET.
