Across
  1. 3. The inside parts of a cell such as the Golgi apparatus, nucleus, ribosomes, microtubules, and storage particles.
  2. 5. A structure that appears during mitosis in animal cells.
  3. 6. A unicellular organism that lacks a nucleus and membrane-bound organelles.
  4. 8. A fluid-filled organelle that stores enzymes or metabolic wastes in a plant cell.
  5. 9. An inherited feature or characteristic.
  6. 11. An organelle that functions in the synthesis of proteins.
  7. 15. The membranous covering of a cell secreted by the cytoplasm in growing plants.
  8. 16. The living substance within a plant or animal cell excluding the nucleus.
  9. 20. An organelle containing digestive enzymes, existing primarily in animal cells.
  10. 21. A small, rounded body within the cell nucleus, functioning in ribosome manufacture.
  11. 22. The gelatin-like aqueous fluid that bathes the organelles on the inside of the cell membrane.
  12. 24. A genetic protein-like nucleic acid on plant and animal genes and chromosomes that controls inheritance. Each DNA molecule consists of two strands in the shape of a double helix.
  13. 25. One of the four bases of DNA; it pairs only with adenine.
  14. 26. Each strand of DNA is a linear arrangement of repeating similar units called nucleotides, which are each composed of one sugar, one phosphate, and a nitrogen base.
  15. 27. A cell that contains genetic information or DNA in the nucleus like most organisms.
Down
  1. 1. The transmission of genetic factors from parent to offspring.
  2. 2. Organelles that are the site of aerobic respiration in eukaryotic cells.
  3. 4. The simplest unit of inheritance. Physically, each gene is apparently a nucleic acid with a unique structure. It influences certain traits.
  4. 5. The semipermeable membrane enclosing the cytoplasm of a cell.
  5. 7. A network of long protein strands in the cytosol that helps maintain the shape and size of a eukaryotic cell.
  6. 10. The ultimate functional unit of an organic structure, plant, or animal. It consists of a microscopic mass of protoplasm, which includes a nucleus surrounded by a membrane.
  7. 12. A system of membranes in eukaryotic cells that modifies proteins for export by the cell.
  8. 13. The brain of the cell. Houses DNA.
  9. 14. Minute objects within plant cells, which contain the green pigment, chlorophyll.
  10. 17. One of the four bases in DNA. It pairs only with thymine.
  11. 18. One of the four bases of DNA; it pairs only with guanine.
  12. 19. Body in the nucleus of the cell that carries the DNA
  13. 23. One of the four bases of DNA; it pairs only with cytosine.
