Photosynthesis, Respiration and Mitosis by Greg S
Across
- 2. a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living
- 5. a simple sugar produced by photosynthesis
- 9. the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells.
- 10. an organism that makes its own food
- 13. a tiny cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
- 18. any of the tiny pores in the epidermis of the leaf or stem of a plant forming a slit of variable width that allows movement of gasses in and out of the cell
- 19. when a cell consumes oxygen and glucose to produce energy it can use
- 20. a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
- 21. the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
- 22. the natural coloring matter of animal or plant tissue
- 23. the material of which the chromosomes of organisms other than bacteria are composed. It consists of protein, RNA, and DNA.
- 24. the gas produced by photosynthesis
- 25. the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears.Metaphase
Down
- 1. the stage of cell division in which the chromosomes move away from one another to opposite poles of the spindle.
- 3. required whit carbon dioxide to produce oxygen by photosynthesis
- 4. cell division in ordinary tissue growth
- 6. cellular goo
- 7. organelle which converts oxygen and nutrients into ATP
- 8. these are protein structures that pull apart the genetic material in a cell when the cell divides.
- 11. a highly regulated membrane barrier that separates the nucleus from the cytoplasm
- 12. the process by which a cell captures energy in sunlight and uses it to make food
- 13. the gas used by plants in photosynthesis
- 14. an organism that cannot make its own food
- 15. each of a pair of curved cells that surround a stoma becoming larger or smaller according to the pressure in the cell
- 16. the region of a chromosome to which the microtubules of the spindle attach, via the kinetochore, during cell division.
- 17. e green pigment present in all green plants and in cyanobacteria responsible for the absorption of light to provide energy for photosynthesis
- 19. a plastid that contains chlorophyll and in which photosynthesis takes place
