Across
  1. 7. the maintenance of a constant internal state in a changing environment.
  2. 11. a group of similar cells that perform a common function.
  3. 13. a covalently bonded compound that contains carbon.
  4. 15. a fat molecule or a molecule that has similar properties examples includes oils,waxes,and steroids
  5. 16. the process in which a cell releases a particle by enclosing the particle in a vessel that then moves to the surface and fuses with the cell membrane.
  6. 17. acid-a molecule made up of subunits called nucleotides
  7. 18. a collection of tissues that carry out a specialized function of the body.
  8. 20. a green pigment that captures light energy for photosynthesis.
  9. 21. the movement of substances across the cell membrane that requires the cell to use the energy.
  10. 22. the process by wich cells use oxygen to produce energy from food.
  11. 23. the diffusion of water through a semipermeable membrane.
  12. 25. rigid structure that surrounds the cell membrane and provides support to the cell.
  13. 26. reticulum- a system of membranes that is found in a cell's cytoplasm and that assists in the production processing and transport of proteins and in the productions of lipids.
  14. 30. - a living thing that can carry out life processes independently.
  15. 32. the movement of substances across a cell membrane without the use of energy by the cell.
  16. 33. the process by which plants algae and some bacteria use sunlight carbon dioxide and water to make food.
  17. 34. smallest unit of an element that maintains the properties of that element.
Down
  1. 1. a molecule that is made up of amino acids and that is needed to build and repair body structures and to regulate processes del cuerpo.
  2. 2. the theory that states that all living things are made up of cells, that cells are basic organisms, that each cell in a multicellular organism has a specific job and that cells come from only existing cells.
  3. 3. the process by which a cell membrane surrounds a particle and encloses the particle in a vessel to bring the particle into the cell.
  4. 4. substance that can not be separated or broken down into simpler substances by chemical means.
  5. 5. the arrangement of parts is an organism.
  6. 6. the cytoplasmic network of protein filaments that plays an essential role in cell movement, shape and division.
  7. 8. a cell organelle that contains digestive enzymes.
  8. 9. the process by which cells use oxygen to produce energy from food.
  9. 10. a cell organelle composed of rna and protein the site of protein synthesis.
  10. 12. cell organelle that helps make a package of material to be transported out of the cell.
  11. 14. is eukaryotic cells a process of cell division that forms to new nuclei each of which has the same number of chromosomes.
  12. 19. a fluid filled vesicle found in the cytoplasm of plant cells or protozoans.
  13. 24. class of molecules that includes sugars, starches and fiber contains carbon hydrogen and oxygen.
  14. 27. a group of organs that work together to perform body function.
  15. 28. the special normal or proper activity of an organ or part.
  16. 29. the movement of particles from regions of higher destiny to regions of lower density.
  17. 31. is eukaryotic cells the organelle that is the site of cellular respiration which releases energy for use by the cell
