cells
Across
- 1. green pigment that captures the light energy that drives the light reactions of photosynthesis
- 3. region in animal cells made of two centrioles
- 5. organelle in an animal cell that functions as the cell’s digestive component; it breaks down proteins, polysaccharides, lipids, nucleic acids, and even worn-out organelles
- 7. (singular = mitochondrion) cellular organelles responsible for carrying out cellular respiration, resulting in the production of ATP, the cell’s main energy-carrying molecule
- 9. entire region between the plasma membrane and the nuclear envelope, consisting of organelles suspended in the gel-like cytosol, the cytoskeleton, and various chemicals
- 10. darkly staining body within the nucleus that is responsible for assembling the subunits of the ribosomes
- 12. theory,see unified cell theory
- 13. semi-solid fluid inside the nucleus that contains the chromatin and nucleolus
- 14. membrane, phospholipid bilayer with embedded (integral) or attached (peripheral) proteins, and separates the internal content of the cell from its surrounding environment
- 16. membrane-bound sac, somewhat larger than a vesicle, which functions in cellular storage and transport
- 19. small, round organelle that contains hydrogen peroxide, oxidizes fatty acids and amino acids, and detoxifies many poisons
- 22. vacuole, 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 macro molecule degradation
- 23. protein-DNA complex that serves as the building material of chromosomes
- 24. gel-like material of the cytoplasm in which cell structures are suspended
- 26. cell, cell that has a membrane-bound nucleus and several other membrane-bound compartments or sacs
Down
- 2. cellular structure that carries out protein synthesis
- 4. structure within the nucleus that is made up of chromatin that contains DNA, the hereditary material
- 6. compartment or sac within a cell
- 8. envelope, double-membrane structure that constitutes the outermost portion of the nucleus
- 11. cell organelle that houses the cell’s DNA and directs the synthesis of ribosomes and proteins
- 15. an instrument that magnifies an object
- 17. wall, rigid cell covering made of various molecules that protects the cell, provides structural support, and gives shape to the cell
- 18. microscope, an instrument that magnifies an object using a beam visible light passed and bent through a lens system to visualize a specimen
- 20. microscope,an instrument that magnifies an object using a beam of electrons passed and bent through a lens system to visualize a specimen
- 21. plant cell organelle that carries out photosynthesis
- 25. 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
