Free Cells word search. We picked 12 themed words — the parts and systems of the human body — and laid them out on a 15×15 grid. Drag across the letters to find every word on the list.
Words to find: NUCLEUS, MITOCHONDRIA, RIBOSOME, GOLGI, LYSOSOME, CENTROSOME, VACUOLE, VESICLE, CYTOSKELETON, CYTOPLASM, CYTOSOL, MITOSIS.
Found words stay highlighted, so the grid gets easier to read as you go and the final few tend to fall quickly.
Cells word list, defined
- NUCLEUS /ˈnjuːkliːəs/ · noun
- The central or most important part of something; the core or essence of something. In biology, the nucleus is the control center of a cell. Related: core, center, essence, heart.
- MITOCHONDRIA /mɪtəʊˈkɒndriə/ · noun
- The organelles found in the cells of most eukaryotes, responsible for generating most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy. Related: organelle, cellular structure, energy-producing organelle, mitochondrion.
- RIBOSOME /ˈraɪbəʊsəm/ · noun
- A small organelle found in cells where protein synthesis takes place, consisting of a complex of ribosomal RNA and proteins. Related: organelle, cellular structure, protein synthesis site, ribonucleoprotein.
- LYSOSOME /ˈlaɪsoʊm/ · noun
- A membrane-bound organelle found in the cells of most eukaryotes, containing digestive enzymes that break down and recycle cellular waste and foreign substances. Related: vacuole, lysosome, autophagosome, endosome.
- CENTROSOME /ˈsɛntrəsoʊm/ · noun
- A small structure near the nucleus of an animal cell that serves as the main microtubule-organizing center, consisting of a pair of centrioles surrounded by pericentriolar material. It plays a central role in organizing the spindle fibers during cell division. Related: microtubule-organizing center, cell pole organizer.
- VACUOLE /ˈvækjuːoʊl/ · noun
- A membrane-bound organelle found in cells, containing waste or excess substances. In botany, a vacuole is a large storage compartment in plant cells. Related: organelle, vesicle, vacuole, lysosome.
- VESICLE /vɛˈsɪkəl/ · noun
- A small, fluid-filled sac or vesicle, especially one that is formed within a cell or tissue. A vesicle can also refer to a small, enclosed space or compartment. Related: sac, blister, bubble, vesicule.
- CYTOSKELETON /ˌsaɪtəʊˈskɛlɪtən/ · noun
- The network of protein filaments and microtubules that gives a living cell its shape, provides mechanical support, and enables internal movement, division, and transport. Related: cellular scaffolding, cytoskeletal framework, microfilament network, intracellular scaffold.
- CYTOPLASM /ˈsaɪtəˌplæzəm/ · noun
- The jelly-like substance, composed mostly of water, salts, and proteins, that fills the interior of a cell and surrounds the nucleus and other organelles; it is the medium in which most cellular metabolic activity occurs. Related: protoplast, cell fluid, cytosol.
- CYTOSOL /ˈsaɪtəˌsɒl/ · noun
- The aqueous component of the cytoplasm of a cell, in which the organelles are suspended and in which many metabolic reactions take place. Related: intracellular fluid, cell sap, hyaloplasm.
- MITOSIS /mɪˈtoʊsɪs/ · noun
- The process of cell division that results in two genetically identical daughter cells, each having the same number and kind of chromosomes as the parent nucleus. Mitosis is a type of eukaryotic cell division. Related: cell division, binary fission, meiosis, reproduction.
