Cells By: Delaney, Mya, and Fatuyamu
Across
- 3. an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur
- 6. organisms whose cells have a nucleus enclosed within membranes
- 8. (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
- 10. the material or protoplasm within a living cell, excluding the nucleus
- 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
- 12. a structural layer surrounding some types of cells, just outside the cell membrane
- 13. a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles
- 14. any of a number of organized or specialized structures within a living cell.
- 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.
- 19. a small dense spherical structure in the nucleus of a cell during interphase.
- 20. a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
Down
- 1. a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells
- 2. a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
- 4. a biological membrane that separates the interior of all cells from the outside environment
- 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.
- 7. the basic unit of life in organisms of the kingdom Animalia
- 9. the basic unit of life in organisms of the kingdom Plantae
- 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.
- 17. an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
- 18. a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material.
