Across
- 3. the process by which plants convert light energy into chemical energy to produce food, using sunlight, carbon dioxide, and water to create glucose and oxygen.
- 4. oval-shaped and possess a double membrane structure with a matrix and cristae.
- 6. a small organelle in cells that breaks down fatty acids and detoxifies harmful substances.
- 9. a gel-like substance that fills the space within the cell membrane, excluding. the nucleus.
- 10. a membrane bound organelle that contains the DNA of the cell.
- 12. a selectively permeable barrier that separates the plant cell's interior from. its surroundings.
- 13. tiny structures responsible for making proteins.
- 15. a specialized, non-membrane-bound structure within the nucleus, primarily responsible for ribosome biogenesis and the transcription of ribosomal RNA (rRNA).
Down
- 1. tiny channels that connect plant cells, allowing the transport of water, nutrients, and signals between them.
- 2. green, disk-shaped structures are essentially the "kitchen" of the plant cell.
- 5. calcium carbonate crystals in plants that help store calcium and may deter herbivores.
- 7. a structural layer surrounding some cells, found outside the plasma membrane.
- 8. a network of protein fibers in a cell that provides structure, support, and helps with movement and transport within the cell.
- 11. DNA wrapped around proteins (histones) that packages and regulates gene activity in the nucleus.
- 14. a large, membrane-bound organelle that occupies a significant portion of the cell's volume.
