Across
- 2. morphogenetic response to a stimulus that results in the organs, embryos, or whole plants
- 5. Organ formation through dedifferentiation of differentiated cells and reorganization of cell division to create particular organ primordia and meristems
- 7. Group of plant growth regulators that regulate growth and shoot morphogenesis and stimulate cell division
- 8. Potential of plant cells to alter their metabolism, growth, and development to best suit their environment
- 10. Structure with both apical and basal meristem regions, which are capable of forming shoot and root, respectively
- 13. Potential of a plant cell to develop into an entire plant if suitably stimulated
- 14. Terminal portion of a shoot (0.5-5 mm) comprising the meristem (0.1-0.5 mm) together with primordial and developing leaves and adjacent stem tissue
- 16. State of cell development characterized by isodiametric cells, with very little or no vacuoles and large nuclei
- 19. Regeneration through growth and proliferation of existing meristems
- 21. Cells of plants (fungi or bacteria) in which the cell walls have been removed, but the plasma membranes are intact
- 23. Tissue taken from its donor plant
- 24. Propagation of plant cells, tissues and organs on nutrient medium under aseptic conditions
- 25. Process whereby somatic cells differentiate into somatic embryos
Down
- 1. Culture of individual cells derived from explant tissue
- 3. Actively dividing and undifferentiated cells at the apices of shoots and roots (0.1-0.5 mm)
- 4. Developing from unusual points of origin, such as shoot tissues, root tissues or callus or embryos, from sources other than zygotes
- 6. Synthetic plant hormone that strongly affects growth (i.e. cytokinins, auxins, and gibberellins)
- 9. Process in which differentiated cells that have lost their ability to divide are reformed from dedifferentiated cells and acquire the ability to perform specific functions
- 11. Nutritive solution, solid or liquid, for culturing cells.
- 12. Process by which cells derived from root apical and shoot apical meristems and cambium mature to perform specific functions
- 15. Group of plant growth regulators that promotes callus growth, cell division, cell enlargement, and lateral rooting
- 17. Part of the plant stem from which a leaf, shoot or flower originates
- 18. Unorganized, proliferating mass of differentiated plant cells
- 20. Process by which mature cells return to a meristematic condition and develop a new growing point
- 22. Free from contamination caused by bacteria, viruses, or other microorganisms
