Across
  1. 3. The cell’s packaging, sorting, and distributing organelle. They sort proteins from the Endoplasmic Reticulum and then distribute them to where they need to go.
  2. 4. Moving things inside and outside of the cell membrane.
  3. 9. All of the chemical reactions that allow a cell to survive; includes the chemical reactions required to release or generate energy, to produce chemicals the body needs such as proteins, and to expel waste.
  4. 10. This transport requires energy to move a substance into and out of a cell. A transport protein called AdenosineTriphosphate (ATP) binds with the molecule and transports it into the cell using the cell’s energy. (When a molecule moves against its concentration gradient, energy is required.))
  5. 11. Organisms that exist that are composed of a single cell (bacteria, yeast, protozoa, and diatoms).
  6. 13. Jelly-like substance in the cell containing all the organelles in the cell. It helps to maintain the structure of the cell.
  7. 14. Transport proteins on the cell’s membrane transport substances into and out of the cell without energy.
  8. 19. The basic structural and functional unit of all forms of life; they are able to replicate independently.
  9. 20. Plants, algae, fungi and some bacteria have an extra computer layer that is very rigid and tough, that helps protect the cell and give it shape.
  10. 24. Organism that is composed of many cells, and many different types of cells that perform different tasks throughout the organism.
  11. 25. The cell’s powerhouse, releasing energy in food by carrying out a reaction with oxygen.
  12. 26. A protective double membrane surrounding the nucleus that controls the flow of materials in and out of the nucleus.
  13. 27. Cells found in animals
  14. 28. The cell’s transport organelle, processing and moving materials throughout the cell.
  15. 29. A small structure found inside the nucleus that makes ribosomes and transports them to the cytoplasm.
Down
  1. 1. The cell’s “control center”, housing the cell’s chromosomes.
  2. 2. The movement of things in and out of the cell without the use of energy.
  3. 5. Cells found in plants (with a cell wall, chloroplasts, and a large, central vacuole for storage that takes up a lot of space)
  4. 6. Very simple, single-celled bacteria that do not have a membrane-bound nucleus, mitochondria, or organelles.
  5. 7. The chemical reaction a plant carries out in order to produce energy from sunlight. Chlorophyll uses the sun’s energy to convert carbon dioxide and water into energy (glucose). Oxygen is released as a waste product.
  6. 8. A type of diffusion; it is simply the process of water molecules from a higher to a lower concentration through a membrane.
  7. 12. Temporary storage bubbles for the cell, storing food, water, or waste.
  8. 15. The movement of molecules from an area of high to low concentration.
  9. 16. In plant cells only, they are organelles that produce food. Chlorophyll is a green pigment that makes plants look green and also uses energy from the sun to change water and carbon dioxide into glucose, a simple sugar.
  10. 17. Organelle that contains digestive chemicals that break down food, cell waste, and foreign particles that enter the cell (i.e. viruses and bacteria). It digests and destroys dead cells and old cell parts and recycles material to make other cells
  11. 18. All organisms are made of cells (one or more) The cell is the basic building block of life (in structure and function);Every cell comes from another existing cell (cells divide to form new cells)
  12. 21. The parts of a cell. They process and release energy, destroy and digest materials, and replicate genetic information.
  13. 22. In every cell, there is a layer on the outside of the cell that holds the cell together, and controls the flow of material in and out of the cell (a semi-permeable layer, allowing some stuff through and keeping other things out).
  14. 23. Much more complex types of cells (containing a membrane-bound nucleus, mitochondria, and organelles) found in protists, fungi, animals and plants.
