Down: 2) Compartment or sac within a cell. 3) See unified cell theory.4) Protein-DNA complex that serves as the chromosomes’ building material.5) The cytoplasm’s gel-like material in which cell structures are suspended.6) Protein fiber network that collectively maintains the cell’s shape, secures some organelles in specific positions, allows cytoplasm and vesicles to move within the cell, and enables unicellular organisms to move independently.7) Channel between two adjacent animal cells that allows ions, nutrients, and low molecular weight substances to pass between cells, enabling the cells to communicate.9) An instrument that magnifies an object using an electron beam that passes and bends through a lens system to visualize a specimen. 10) Region of the endoplasmic reticulum that is studded with ribosomes and engages in protein modification and phospholipid synthesis. 12) Plant cell organelle that carries out photosynthesis.14) Eukaryotic organelle comprised of a series of stacked membranes that sorts, tags, and packages lipids and proteins for distribution.15) A biological concept that states that one or more cells comprise all organisms; the cell is the basic unit of life; and new cells arise from existing cells.17) The cytoskeleton system’s narrowest element; it provides rigidity and shape to the cell and enables cellular movements.19) Phospholipid bilayer with embedded (integral) or attached (peripheral) proteins, and separates the cell’s internal content from its surrounding environment.20) Protein adherence that creates a firm seal between two adjacent animal cells.22) Membrane-bound sac, somewhat larger than a vesicle, which functions in cellular storage and transport.30) (plural = plasmodesmata) Channel that passes between adjacent plant cells’ cell walls, connects their cytoplasm, and allows transporting of materials from cell to cell.34) Cell organelle that houses the cell’s DNA and directs ribosomes and protein synthesis.36) (plural = cilia) Short, hair-like structure that extends from the plasma membrane in large numbers and functions to move an entire cell or move substances along the cell’s outer surface. Across: 1) Central part of a prokaryotic cell’s central part where the chromosome is located.3) Entire region between the plasma membrane and the nuclear envelope, consisting of organelles suspended in the gel-like cytosol, the cytoskeleton, and various chemicals. 8) Rigid cell covering comprised of various molecules that protects the cell, provides structural support, and gives shape to the cell. 9) Material secreted from animal or fungal cells that provides mechanical protection and anchoring for the cells in the tissue.11) Unicellular organism that lacks a nucleus or any other membrane-bound organelle.13) Small, round organelle that contains hydrogen peroxide, oxidizes fatty acids and amino acids, and detoxifies many poisons.16) Linkages between adjacent epithelial cells that form when cadherins in the plasma membrane attach to intermediate filaments.18) Cellular structure that carries out protein synthesis.21) Group of organelles and membranes in eukaryotic cells that work together modifying, packaging, and transporting lipids and proteins.23) (plural = flagella) Long, hair-like structure that extends from the plasma membrane and moves the cell.24) Region in animal cells made of two centrioles that serves as an organizing center for microtubules. 25) An instrument that magnifies an object. 26) The cytoskeleton system’s widest element; it helps the cell resist compression, provides a track along which vesicles move through the cell, pulls replicated chromosomes to opposite ends of a dividing cell, and is the structural element of centrioles, flagella, and cilia.27) (singular = mitochondrion) Cellular organelles responsible for carrying out cellular respiration, resulting in producing ATP, the cell’s main energy-carrying molecule.28) Large plant cell organelle that regulates the cell’s storage compartment, holds water, and plays a significant role in cell growth as the site of macromolecule degradation.29) Cell that has a membrane-bound nucleus and several other membrane-bound compartments or sacs.31) Series of interconnected membranous structures within eukaryotic cells that collectively modify proteins and synthesize lipids.32)  Small, membrane-bound sac that functions in cellular storage and transport; its membrane is capable of fusing with the plasma membrane and the membranes of the endoplasmic reticulum and Golgi apparatus.33) Double-membrane structure that constitutes the nucleus’ outermost portion34) Darkly staining body within the nucleus that is responsible for assembling ribosome subunits.35) Semi-solid fluid inside the nucleus that contains the chromatin and nucleolus.37) An instrument that magnifies an object using a beam of visible light that passes and bends through a lens system to visualize a specimen. 38) Organelle in an animal cell that functions as the cell’s digestive component; it breaks down proteins, polysaccharides, nucleic acids, and even worn-out organelles.39) Structure within the nucleus that comprises chromatin that contains DNA, the hereditary material.40) Region of the endoplasmic reticulum that has few or no ribosomes on its cytoplasmic surface and synthesizes carbohydrates, lipids, and steroid hormones, detoxifies certain chemicals (like pesticides, preservatives, medications, and environmental pollutants), and stores calcium ions.41) Region in animal cells made of two centrioles that serves as an organizing center for microtubules. 42) Cytoskeletal component, comprised of several fibrous protein intertwined strands, that bears tension, supports cell-to-cell junctions, and anchors cells to extracellular structures.
