Across
- 1. organelle composed of a double membrane that acts as the store house of most of the cells DNA.
- 3. cell that has a nucleus or any other membrane bound organelles.
- 5. movement of large particles into the cell.
- 7. moves substances against the concentration gradient (require energy).
- 9. moves substances down the concentration gradient ( does not require energy).
- 11. these small structures that function as factories to produce proteins.
- 12. boundary that separates cells from their environment & controls what goes in and out of the cell.
- 15. this network of passage ways carries materials from one part of the cell to another.
- 18. carries out photosynthesis.
- 19. most of the cells energy is produced within these red-shaped organelles.
- 20. located inside the nucleus where ribosomes are made.
Down
- 2. only certain substances are allowed to pass through the membrane.
- 4. cell that does not have a nucleus or any other membrane organelles.
- 6. some animal cells have vacuole that store food, water, waste, and other materials.
- 8. membrane bound structure that is specialized to perform a distinct process within a cell.
- 10. membrane bounded structure that is specialized to perform a distinct process within a cell.
- 13. protection, support to plant cell, fungi, algae & bacteria.
- 14. recieves materials from the E.R. and sends them to other parts of the cell.
- 16. movement of large particles out of the cell.
- 17. a unit that makes up living things from microscopic organisms to the most complex.
