Cells Word Search
Cells, as a word search. 12 words drawn from the terms and ideas of a school subject sit hidden in a 15×15 letter grid, running in every direction. Drag across a word to claim it, and clear the board to finish.
Words to find: NUCLEUS, CYTOPLASM, MITOCHONDRIA, MEMBRANE, RIBOSOME, ORGANELLE, CHLOROPLAST, VACUOLE, GOLGI, LYSOSOME, ENDOPLASMIC, PROKARYOTE.
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 /ˈnuːkliəs/ · noun
- A nucleus is the central, typically rounded part of an atom or biological cell, containing genetic material and playing a central role in the cell's activity. More broadly, the term refers to a central, fundamental, or defining part of something. Related: core, center, centre, heart.
- 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.
- MITOCHONDRIA /ˌmaɪtəʊˈkɒndriə/ · noun
- A small, membrane-bound organelle found in most eukaryotic cells, where cellular respiration produces ATP, the cell’s main usable energy source. Mitochondria also participate in other metabolic and regulatory processes. Related: cellular powerhouses, energy-producing organelles, respiratory organelles.
- MEMBRANE /ˈmɛm.breɪn/ · noun
- A thin, flexible sheet or layer of material that separates, covers, or forms part of a larger structure. In biology, the term refers to a specialized layer of tissue or lipid bilayer that encloses or separates cells and organs. Related: layer, film, sheath, covering.
- RIBOSOME /ˈraɪbəˌsoʊm/ · noun
- A small cellular structure made of ribosomal RNA and proteins that assembles amino acids into proteins. Ribosomes occur free in the cytoplasm or attached to the endoplasmic reticulum, as well as inside mitochondria and chloroplasts. Related: ribonucleoprotein complex, protein-synthesizing complex, translation apparatus.
- ORGANELLE /ˈɔːɡəˌnɛl/ · noun
- A specialized structure within a cell that performs one or more specific functions. Organelles may be surrounded by a membrane, as in mitochondria and the nucleus, or may not be, as in ribosomes. Related: subcellular structure, cellular structure, cell component.
- CHLOROPLAST /ˈklɔːrəplæst/ (US), /ˈklɒrəplɑːst/ (UK) · noun
- A chloroplast is a plastid in plant and algal cells that contains the green pigment chlorophyll, where photosynthesis takes place. It converts light energy into chemical energy stored as sugars. Related: chlorophyll body, plastid, photosynthetic organelle.
- VACUOLE /ˈvækjuoʊl/ · noun
- A membrane-bound, fluid-filled compartment within a cell. Vacuoles store substances and may also be involved in digestion, waste removal, and maintaining internal pressure.
- LYSOSOME /ˈlaɪsəˌsoʊm/ · noun
- A membrane-bound compartment in a cell that contains digestive enzymes and breaks down certain molecules, cellular waste, and worn-out organelles. Lysosomes also help defend cells by destroying some ingested pathogens. Related: cellular digestive vesicle, enzyme-containing vesicle, suicide bag.
- ENDOPLASMIC /ˌɛndəʊˈplæzmɪk/ · adjective
- Relating to or located in the endoplasm, the dense inner portion of a cell's cytoplasm that surrounds the nucleus. Related: intracellular, cytoplasmic.
- PROKARYOTE /ˌproʊkæriˈoʊt/ · noun
- A single-celled organism whose cells lack a membrane-bound nucleus and the other membrane-bound organelles characteristic of eukaryotes. Prokaryotes include bacteria and archaea. Related: prokaryotic organism, prokaryotic cell, moneran.
