Description: A cell is the basic unit of life, containing organelles like nucleus and mitochondria, enclosed by a cell membrane.
Description: Microorganisms are tiny living organisms invisible to the naked eye, including bacteria, viruses, fungi, and protists.
Description: Respiration in plants involves the process of converting glucose into energy, releasing carbon dioxide and water as byproducts.
Description: Respiration in animals involves inhaling oxygen and exhaling carbon dioxide to produce energy through cellular respiration in various body tissues.
Description: Reproduction in plants involves the creation of new plants through processes like pollination, fertilization, and seed dispersal.
Description: Reproduction in animals involves the creation of offspring through sexual or asexual means, ensuring the continuation of the species.
Description: Conservation of natural resources involves sustainable management to ensure their availability for present and future generations, preserving biodiversity and ecosystems.
Description: Elements are fundamental substances made up of atoms with the same number of protons, defining their unique chemical properties.
Description: Atoms are basic units of matter, consisting of protons, neutrons, and electrons. Molecules are groups of atoms bonded together chemically.
Description: States of matter are solid, liquid, gas, and plasma, determined by particle arrangement, energy, and interaction at given conditions.
Description: Metals are elements with metallic properties, conducting heat and electricity. Non-metals lack these properties and are often insulators.
Description: Physical change alters the form of a substance without changing its chemical composition, while chemical change involves chemical reactions.
Description: Reactants are substances entering a chemical reaction, while products are substances formed as a result of that reaction.
Description: Motion is the change in position of an object over time, while time is a measure of duration or intervals.
Description: Force is a push or pull applied to an object, while pressure is force distributed over a surface area, measured in Pascals.
Description: Newton's laws of motion describe how objects move: inertia, force equals mass times acceleration, and action and reaction forces.
Description: Work is the transfer of energy by a force acting on an object, while energy is the capacity to do work.
Description: Light is electromagnetic radiation visible to the human eye, carrying energy, illuminating objects, and enabling vision and photosynthesis.
Description: Electric current is the flow of electric charge, usually carried by electrons through a conductor, resulting from voltage difference.
Description: Gravity is the natural force of attraction between objects with mass, causing them to move toward each other.
