NEET BIOLOGY

Detailed explanation-1: -The main ingredient of cells is water. Water is needed to maintain homeostasis. Cells are also made up of macromolecules-nucleic acids, lipids, proteins, carbohydrates. These macromolecules help maintain a cell’s structure, help cells communicate with each other, aid in energy storage, etc.

Detailed explanation-2: -Cells are composed of water, inorganic ions, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.

Detailed explanation-3: -Cytoplasm is the gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules. Some intracellular organelles, such the nucleus and mitochondria, are enclosed by membranes that separate them from the cytoplasm.

Detailed explanation-4: -Water allows everything inside cells to have the right shape at the molecular level. As shape is critical for biochemical processes, this is also one of water’s most important roles. Figure 2: Water impacts cell shape. Water creates pressure inside the cell that helps it maintain shape.

Detailed explanation-5: -Water is crucial to keep the body working correctly. It is present in the blood, skin, organs, and bones. There is water in every cell of the body, from the brain to the teeth.
