Across
  1. 3. an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur
  2. 6. organisms whose cells have a nucleus enclosed within membranes
  3. 8. (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
  4. 10. the material or protoplasm within a living cell, excluding the nucleus
  5. 11. a genetic structure in a cell that can replicate independently of the chromosomes, typically a small circular DNA strand in the cytoplasm of a bacterium or protozoan
  6. 12. a structural layer surrounding some types of cells, just outside the cell membrane
  7. 13. a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles
  8. 14. any of a number of organized or specialized structures within a living cell.
  9. 15. a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis.
  10. 19. a small dense spherical structure in the nucleus of a cell during interphase.
  11. 20. a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
Down
  1. 1. a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells
  2. 2. a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
  3. 4. a biological membrane that separates the interior of all cells from the outside environment
  4. 5. a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
  5. 7. the basic unit of life in organisms of the kingdom Animalia
  6. 9. the basic unit of life in organisms of the kingdom Plantae
  7. 16. a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
  8. 17. an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
  9. 18. a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material.
