PHOTOSYNTHESIS

Photosynthesis :                     Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into oxygen and sugar. It is the foundation of the food chain and the basis for all life on Earth.                     Photosynthesis takes place in the chloroplasts of plant cells. Chloroplasts are small organelles that contain chlorophyll, a green pigment that absorbs sunlight. When sunlight hits chlorophyll, it excites the electrons in the chlorophyll molecule. These excited electrons then flow through a series of proteins called an electron transport chain. As the electrons flow through the electron transport chain, they release energy. This energy is used to pump hydrogen ions across a membrane. The hydrogen ions then flow back down the gradient, and this flow of ions generates ATP, the cell's main energy currency.     ...

STATES OF MATTER

Physical States of Matter :                     Matter is anything that has mass and takes up space. It can be found in three different physical states: solid, liquid, and gas.                    1. Solids have a definite shape and volume. The particles in a solid are tightly packed together and vibrate in place. This is why solids have a fixed shape and cannot be easily compressed.                 2. Liquids have a definite volume but no definite shape. The particles in a liquid are still close together, but they are able to move around each other. This is why liquids can flow and take the shape of their container.                    3. Gases have no definite shape or volume. The particles in a gas are very far apart and move around very quickly. This ...

PHYSICIAL QUANTITIES

PHYSICIAL QUANTITIES :                                                                        A physical quantity is a property of a material or system that can be quantified by measurement. A physical quantity can be expressed as a value, which is the algebraic multiplication of a ' Numerical value ' and a ' Unit '. For example, the physical quantity of mass can be quantified as '32.3 kg ', where '32.3' is the numerical value and 'kg' is the Unit. A physical quantity possesses at least two characteristics in common. Dimensions: A physical quantity has a certain number of dimensions, which are the basic units of measurement that are used to quantify it. For example, the dimensions of mass are length, mass, and time. Units: A physical quantity has a certain unit of measureme...
