ACTIVE – Describes cells or processes that are functioning, moving, or requiring energy to transport materials across membranes against concentration gradients through active transport mechanisms.
ANIMAL – Multicellular organisms whose cells lack cell walls and chloroplasts. Animal cells contain centrioles and often have smaller vacuoles compared to plant cells for various functions.
BODY – The complete physical structure of an organism, composed of trillions of specialized cells working together in tissues, organs, and organ systems to maintain life.
CELL WALL – A rigid outer layer surrounding plant, fungal, and bacterial cells, providing structural support and protection. Made primarily of cellulose in plants, maintaining cell shape.
CYTOPLASM – The gel-like substance filling the cell between the nucleus and membrane, containing organelles, proteins, and nutrients. Site of many metabolic reactions and cellular activities.
DIVISION – The process by which cells reproduce, splitting into two daughter cells through mitosis or meiosis, enabling growth, repair, and reproduction in living organisms.
DNA – Deoxyribonucleic acid, the hereditary material containing genetic instructions for development, functioning, and reproduction. Forms a double helix structure storing information in nucleotide sequences.
ENDOPLASM – The inner, more fluid portion of cytoplasm in certain cells, particularly amoebas. Contains organelles and is distinct from the outer, more gel-like ectoplasm layer.
ENZYME – Biological catalysts that speed up chemical reactions in cells without being consumed. Proteins with specific shapes that bind to substrates, lowering activation energy required.
FLAGELLA – Whip-like appendages extending from certain cells, enabling movement through liquid environments. Longer than cilia, they propel cells by rotating or undulating in coordinated patterns.
GAMETE – Reproductive cells (sperm or egg) containing half the normal chromosome number. They unite during fertilization to form a zygote with complete genetic information.
GOLGI – Also called Golgi apparatus or Golgi body, this organelle modifies, packages, and distributes proteins and lipids received from the endoplasmic reticulum throughout the cell.
LIPID – Fat molecules including oils, waxes, and steroids that store energy and form cell membranes. Hydrophobic compounds essential for cellular structure, signaling, and insulation.
MEMBRANE – A thin, flexible barrier surrounding cells and organelles, controlling substance passage. Made of phospholipid bilayers with embedded proteins, maintaining cellular integrity and selective permeability.
MITOSIS – Cell division process producing two identical daughter cells from one parent cell. Ensures equal distribution of duplicated chromosomes, essential for growth and tissue repair.
NUCLEUS – The cell’s control center containing genetic material (DNA) organized into chromosomes. Surrounded by a nuclear envelope, it regulates gene expression and cellular activities.
ORGAN – A structure composed of different tissues working together to perform specific functions within an organism, such as the heart, lungs, liver, or brain.
ORGANELLE – Specialized structures within cells performing specific functions, such as mitochondria for energy production, ribosomes for protein synthesis, or lysosomes for digestion and waste removal.
PLANT – Organisms with cells containing cell walls, chloroplasts for photosynthesis, and large central vacuoles. They produce their own food using sunlight, water, and carbon dioxide.
PROTEIN – Large molecules made of amino acid chains, performing diverse cellular functions including structural support, enzyme catalysis, transport, signaling, and immune defense throughout the body.
RIBOSOME – Small organelles responsible for protein synthesis by reading messenger RNA sequences and assembling amino acids into polypeptide chains. Found free or attached to endoplasmic reticulum.
RNA – Ribonucleic acid, a nucleic acid that copies and transmits genetic information from DNA. Essential for protein synthesis, existing as messenger, transfer, and ribosomal forms.
TISSUE – Groups of similar cells working together to perform specific functions. Four main types exist: epithelial, connective, muscle, and nervous tissue in animal bodies.
VACUOLE – Membrane-bound sacs storing water, nutrients, or waste products within cells. Plant cells have large central vacuoles maintaining turgor pressure; animal cells have smaller ones.

A cell is the smallest unit of life capable of functioning independently. All living organisms are composed of one or more cells that perform essential life processes.
Plant cells have cell walls, chloroplasts, and large central vacuoles, while animal cells lack these structures but contain centrioles. Both share common organelles like nucleus and mitochondria.
The nucleus serves as the cell’s control center, storing genetic material (DNA) and directing cellular activities. It regulates gene expression, coordinates growth, and controls reproduction processes.
Cells produce energy through cellular respiration in mitochondria, converting glucose and oxygen into ATP (adenosine triphosphate), the cell’s primary energy currency for all activities.
Stem cells are undifferentiated cells capable of developing into various specialized cell types. They’re crucial for growth, tissue repair, regeneration, and hold significant potential for medical treatments.
Each cell works together in a coordinated system, constantly communicating, dividing, and performing specialized functions to keep you alive, healthy, and functioning properly every single day.
Your body continuously produces millions of new red blood cells every second to replace dying ones, ensuring constant oxygen delivery throughout your entire body without interruption.
Measuring about 0.1 millimeters in diameter, the ovum is visible to the naked eye, while the smallest cell is the male sperm at approximately 0.005 millimeters.
Your body hosts roughly 39 trillion bacterial cells compared to 37 trillion human cells, forming a complex microbiome essential for digestion, immunity, and overall health maintenance.
The longest cells in your body are neurons extending from your spine to your toes, transmitting electrical signals at speeds up to 268 miles per hour.
