Cells review

5. Acts as the “packaging and shipping center” of the cell and receives proteins from the ER.
6. Present only in plant cells and contains a green-coloured pigment known as chlorophyll.
7. Cells with more than 2,000 mitochondria.
11. wall Maintains cell shape.
13. Gel-like, water-rich substance inside the cell that contains organelles and is the site of most cellular activities like metabolism and waste breakdown.
14. The study of cells and living things.
15. A double-membrane-bound organelle found in most eukaryotic organisms that generates most of cell`s ATP.
19. Are cells that enclose their DNA in nuclei.
23. All living plants are made of cells.
24. Organelle that can store many materials.
25. Long, whip-like protrusions that aid in cellular locomotion.
26. Surrounds and protects the nucleus; contains pores for transport.

1. Where a cell exists, there must have been a pre-existing cell
2. Cells without mitochondria.
3. Gel-like substance inside the nucleus.
4. Dense structure that makes ribosomes.
8. Organelle that folds, processes and transports proteins to the Golgi apparatus.
9. Observed dead cells in cork.
10. Protective barrier that separates the cell from its environment. It controls what enters and leaves the cell, maintaining balance
12. Are cells that do not have nuclei.
16. DNA and proteins arranged in threads.
17. Cell structures responsible for protein production.
18. Is a membrane-bound organelle in eukaryotic cells that contains most of the cell’s genetic material, organized as DNA and proteins into chromosomes.
20. All living animals are made of cells.
21. Hair-like structures on the surface of the cell that attach to other bacterial cells.
22. Structural,functional,biological unit of living things.
