Key Elements for Plant Nutrition02:35

Key Elements for Plant Nutrition

22.4K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Mineral, Vitamin and Water Absorption01:27

Mineral, Vitamin and Water Absorption

818
Electrolytes are essential minerals and ions primarily obtained from the diet and absorbed through the gastrointestinal tract. Most electrolytes are absorbed in the small intestine. While the absorption of iron and calcium primarily occurs in the duodenum, calcium is also absorbed in the jejunum and ileum. In these regions, passive diffusion contributes to its absorption alongside active transport mechanisms in the duodenum. These ions can exit the enterocytes through specialized active...

Water and Mineral Acquisition

33.9K
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

Role of Water in Human Biology

11.2K
Water is the one of the most significant components of the human body; it plays a crucial role in several physiological activities because of its unique physicochemical properties. Importantly, it helps to regulate body temperature and is the chief component of several body fluids.
Water's Solvent Properties
Since water is a polar molecule with slightly positive and slightly negative charges, ions and polar molecules can readily dissolve in it. Therefore, it is referred to as a solvent, a...

Compounds Essential to Human Function

9.1K
The human body is composed of cells that are fundamentally made up of several different molecules. These molecules are essential to carry out all physiological processes in the body and are broadly classified into organic and inorganic based on their chemical structures.
Inorganic Compounds Essential to Human Functioning
Inorganic compounds essential to human functioning include water, salts, acids, and bases. These compounds are inorganic, i.e., they do not have a carbon-hydrogen bond. Water...

Requirements for Human Life01:26

Requirements for Human Life

11.4K
The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Area of Science:

  • Dermatology and Physiology
  • Biochemistry and Environmental Science

Background:

  • Water is essential for cellular homeostasis, nutrient transport, and waste removal.
  • While water's importance for skin is known, optimal hydration strategies and daily intake remain debated.
  • Skin hydration is critical for maintaining the skin barrier function and overall health.

Purpose of the Study:

  • To review the cellular and molecular mechanisms of skin hydration.
  • To examine current recommendations and ongoing research regarding daily water consumption for health.
  • To explore the impact of water properties (e.g., hardness) and pollutants on skin physiology.

Main Methods:

  • Literature review of cellular and molecular biology of skin hydration.
  • Analysis of current research on internal and external hydration interventions.
  • Exploration of water chemistry and environmental factors affecting skin.

Main Results:

  • Water is vital for skin's cellular functions and barrier integrity.
  • Research on optimal daily water intake and specific hydration methods is ongoing.
  • Water hardness and pollutants can negatively influence skin hydration and health.

Conclusions:

  • Understanding water's role in skin physiology is key to developing effective hydration strategies.
  • Further research is needed to establish clear guidelines for daily water consumption and topical hydration.
  • Environmental factors like water quality significantly impact skin health and require consideration.
