Across
- 3. A specialized subunit within a cell that has a specific function.
- 5. The gel-like substance within a cell that suspends the organelles; the protoplasm excluding the nucleus.
- 8. The part of the cell that contains the genetic material (DNA) and directs all cell activities.
- 10. The part that connects the body tube to the base.
- 12. An organelle responsible for generating most of the cell's supply of energy, in the form of ATP.
- 15. A membrane-bound sac that can store water, nutrients, or waste products.
- 17. body An organelle that processes, packages, and sorts proteins and other molecules for delivery.
- 19. Reticulum A network of membranes involved in protein and lipid synthesis.
- 20. A network of protein filaments and tubules that gives the cell its shape and coherence.
- 21. Particles in the cytoplasm that are responsible for synthesizing proteins.
- 23. The lens the user looks through to see the magnified image.
Down
- 1. The bottom, weighted part of the microscope that provides stability.
- 2. The light source that shines through or onto the specimen.
- 4. A device that controls the amount of light passing through the specimen.
- 6. membrane The protective outer covering of the cell that is semipermeable, allowing some substances to pass through.
- 7. Organelles in plant cells where photosynthesis takes place.
- 9. The flat plate where the slide is placed for observation.
- 11. A thread-like structure made of DNA that carries genetic information.
- 13. A structure made up of different types of tissues that work together to perform a particular function.
- 14. A group of similar cells that work together to perform a specific function.
- 16. The basic structural, functional, and biological unit of all known organisms.
- 18. A membrane-bound organelle containing digestive enzymes.
- 22. Lens The lens closest to the specimen, which provides the initial magnification.
