Across
- 3. Small openings on plant leaves and stems that allow gas exchange (CO₂ in, O₂ out) and transpiration.
- 8. Vascular tissue in plants that transports water and dissolved minerals from roots to other parts of the plant.
- 9. The central part of a plant root or stem containing vascular tissue (xylem and phloem).
- 10. A type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes of the parent cell.
- 11. Hollow protein tubes in the cytoskeleton that maintain cell shape, guide organelle movement, and form the spindle during cell division.
- 13. Regions of undifferentiated plant cells that can divide and develop into various tissues, responsible for plant growth.
- 15. Membrane-bound organelles that produce energy (ATP) through cellular respiration.
- 18. The living part of a plant cell, including the cytoplasm, nucleus, and other organelles, but not the cell wall.
- 19. The basic structural and functional unit of all living organisms.
Down
- 1. A cell organelle that modifies, sorts, and packages proteins and lipids for transport inside or outside the cell.
- 2. Membrane-bound organelles in cells used for storage of water, nutrients, and waste; large in plant cells.
- 4. Thin, thread-like protein fibers in the cytoskeleton that help with cell shape, movement, and division.
- 5. The molecule that carries genetic information in cells.
- 6. Small organelles that break down fatty acids and detoxify harmful substances using enzymes.
- 7. Groups of similar cells that work together to perform a specific function.
- 12. Organisms whose cells have a nucleus and other membrane-bound organelles.
- 14. Small structures in cells that synthesize proteins by translating RNA.
- 16. A rigid outer layer found in plant cells, fungi, and some bacteria that provides structure and protection.
- 17. Membrane-bound organelle in eukaryotic cells that contains the cell’s DNA and controls activities.
