Across
- 1. the cells transport organelle, processing and moving materials throughout the cell.
- 3. Glucose in food reacts with oxygen, producing carbon dioxide, water and energy in the mitochondria; waste products are carbon dioxide and water.
- 4. the basic function unit of all forms of life; they are able to replicate independ gelles the part of a cell. they process and release energy,destroy and digest materials,and replicate genetic information.
- 7. Organisms that exist that are composed of a single cell (bacteria, yeast, protozoa, and diatoms).
- 8. in plant cells only, they are orangelles 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 and simple sugar.
- 11. orangelle that contains digestive chemicals that break down food,cell waste,and foreign particlesbacteriater the cell (i.e. viruses and batctria)
- 12. The cell’s powerhouse, releasing energy in food by carrying out a reaction with oxygen.
- 15. Transport proteins on the cell’s membrane transport substances into and out of the cell without energy.
- 17. protien-making factories in a cell
- 18. The movement of molecules from an area of high to low concentration.
- 20. Much more complex types of cells (containing a membrane-bound nucleus, mitochondria, and organelles) found in protists, fungi, animals and plants.
- 22. Organisms that exist that are composed of a single cell (bacteria, yeast, protozoa, and diatoms).
- 23. 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.))
- 24. 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.
Down
- 2. in every cell, there is a layer on the outside of the cell that holds the cells together, and controls the flow of a material in and out of the cell(a semi-permeable layer,allowing some stuff through and keeping other things out.)
- 5. Very simple, single-celled bacteria that do not have a membrane-bound nucleus, mitochondria, or organelles.
- 6. 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.
- 9. 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.
- 10. A type of diffusion; it is simply the process of water molecules from a higher to a lower concentration through a membrane.
- 13. 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.
- 14. The movement of things in and out of the cell without the use of energy.
- 16. Molecules that help a chemical reaction proceed.
- 19. Another chemical reaction where energy is released through the breakdown of food; occurs where oxygen is not present. One waste product is Lactic Acid (which causes muscles to cramp when it builds up).
- 21. cells found in animals
