Across 3. A cell structure that contains nucleic acids, the chemical instructions that direct all the cell's activities. 5. Doubled rod of condensed chromatin: contains DNA that carries genetic information. 6. energy-rich organic compound made of the three elements carbon, hydrogen and oxygen. 11. Chromosome sets assemble at opposite poles, a nuclear envelope reforms around each set, and cytokinesis (division of the cytoplasm) usually follows. 13. HָO 14. Sister chromatids separate, and the now-daughter chromosomes move to opposite poles of the cell. 15. The stage of the cell cycle during which the cell's nucleus divides into two new nuclei and one copy of DNA is distributed into each daughter cell. 17. COָ 20. A tiny cell that is able to grow into a new organism. 21. An organism that cannot make its own food 23. CָHָOָ + 6 Oָ -------- 6 COָ + 6 HָO + energy 25. An organism that makes its own food. 26. A close relationship between two organisms in which at least one of the organisms benefits. 27. Structure in the cells of plants that captures energy from sunlight and uses it to produce food. 29. A chemical that produces color. 30. Small openings on the underside of a leaf through which oxygen and carbon dioxide can move.

Down 1. The chromosomes become arranged on the metaphase plate and are attached to the now fully formed spindle. 2. 6 COָ + 6 HָO -light energy- CָH¹ָOָ + 6 Oָ 4. Oָ 7. The process by which a cell makes a copy of the DNA in its nucleus 8. The process by which plants and some other organisms capture the energy in sunlight and use it to make food. 9. Number in front of a chemical formula in an equation that indicates how many molecules or atoms of each reactant and product are involved in a reaction. 10. Type of cell division occurring in the reproduction of germ cells at the time of gamete formation. This process occurs both n plants and animals. 12. Photosynthesis and Respiration 16. Provides energy for cells without using oxygen. 18. The process by which cells break down simple food molecules to release the energy they contain. 19. Chromosomes become visible, the nucleolus disappears, the mitotic spindle forms, and the nuclear envelope disappears. 22. The genetic material that carries information about an organism and is passed from parent to child. 24. A eukaryotic organism that cannot be classified as an animal, plant or fungus. 28. Basic Unit of structure in all living things
