Across 5. Inside parts of a cell ex. nucleus, golgi apparatus, and ribosomes 6. A directional or positional term meaning away from the middle or toward the side 9. Unit of protoplasm in one cell 12. Particle that lies along the endoplasmic reticulum and is composed of a protein portion and RNA; site of protein synthesis 13. Chemical process that takes place in living cells whereby food is oxidized ("burned") to release energy and waste products, mostly carbon dioxide and water 14. Organelle bounded by a membrane and containing enzymes capable of breaking down proteins and other molecules 15. Cell organelle composed of an outer membrane and a winding inner membrane. A series of chemical reactions that occur on the inner membrane convert the energy of oxidation into the chemical energy of ATP; "The powerhouse of the cell" 20. Plant having a single cotyledon or seed leaf ex. corn 24. Living substance within a plant or animal cell excluding the nucleus 25. Plant whose seed have two cotyledons or seed leaves ex. beans 27. Semipermeable film, composed of lipids and proteins, enclosing the cytoplasm and organelles of a cell 28. Cellular layer of an organism 31. Process in which green plants produce carbohydrates from water and carbon dioxide and release oxygen, using chlorophyll and the energy of sunlight 32. Cavity that is in the cytoplasm, filled with a watery fluid, bound by membrane; considered not living 33. Type of cell containing genetic information or DNA contained in the nucleus of the cell ex. plant and animal cells 34. "Plumbing" system that conducts water and dissolved minerals up the stem from the roots

Down 1. Branch of biology that deals with the structure of organisms 2. Ultimate functional unit of an organic structure, plant or animal 3. Minute protoplasmic body sometimes held to be the dynamic center of the mitotic activity 4. Pertaining to organisms that only grow in the presence of oxygen 7. Central portion of the cell protoplast surrounded by a thin membrane. Considered like the brain of a cell 8. Living or active in the absence of free oxygen 10. Type of cell with DNA not enclosed in a nucleus ex. bacteria 11. Structure extending throughout the cytoplasm of a cell. Functions in transporting of cell products and as a surface for protein synthesis by the ribosomes 16. Cell organelle, important for glycosylation and secretion in cells 17. Uses oxygen to carry out catabolic reactions in plant cells 18. Gelatinous, colloidal material of plants and animals in which all life activities occur 19. Plant tissue capable of cell division and therefore responsible for growth 21. Relating to the apex or tip of shoots and roots 22. Physical and chemical processes in an organism by wich living matter is produced, maintained, and destroyed, and by means of which energy is made available 23. Spherical body found within the nucleus of a eukaryotic cell 26. Cells with thin cell walls and large vacuoles. Contains chloroplasts for photosynthesis 29. Group of cells working together to carry out a common function ex. muscle tissue, connective tissue, and epithelial tissue 30. Inner bark; tissue concerned with the translocation of elaborated food produced in carbohydrates in the leaves or other areas, downward in the branches, stems, and roots
