Across
- 3. The process by which organic substances move through the phloem of a plant
- 4. Hole through the testa where seed was attached to parent plant
- 5. A class of related plant hormones that stimulate growth in the stem and leaves, trigger the germination of seeds and breaking of bud dormancy, and stimulate fruit development with auxin.
- 9. A plant's response to light
- 15. The movement of seeds away from a parent plant
- 18. Transport Energy-requiring process that moves material across a cell membrane against a concentration difference
- 21. Plant cells associated with controlling neighbouring sieve cells
- 22. A type of plant that produces flowers and whose seeds are contained in fruit
- 25. An animal that carries pollen from one plant to another of the same species, enabling plants to reproduce.
- 27. Embryonic root
- 29. Plants that tolerate higher salt concentrations.
- 30. Substance in vascular plants that makes cell walls rigid
- 31. The transfer of pollen from male reproductive structures to female reproductive structures in plants
- 33. Embryonic plant tissue in the tips of roots and in the buds of shoots that supplies cells for the plant to grow in length.
- 34. Part of stem where growth occurs, contains meristem tissue that is capable of quick growth
- 35. The early growth of a seed. Requires water and warmth
- 36. Plants that have adapted to dry climates
- 38. The device used to measure the amount of transpiration occurring from a plant
- 39. Plants that flower when nights are longer than a critical length
- 40. Growth response of a plant toward or away from a stimulus
Down
- 1. A plant's response to seasonal changes in length of night and day.
- 2. Loading the active transport of sucrose into a sieve tube element
- 6. The major auxin produced in plants
- 7. these plants flower when nights are SHORTER than a critical length
- 8. Process by which a gene produces its product and the product carries out its function.
- 10. Non-living vascular tissue that carries water and dissolved minerals from the roots of a plant to its leaves
- 11. Aphids are green insects that feed on phloem sap. The stylet is their mouth part that penetrates the phloem vessel
- 12. Seed coat
- 13. Evaporation of water from the leaves of a plant
- 14. Growth response to gravity
- 16. A subdivision of flowering plants whose members possess an embryonic seed leaf made of two halves or cotyledons
- 17. Light receptor pigment that controls photoperiodism. There are 2 types - Pr (red-light absorbing) vs Pfr (infrared light absorbing). Pfr is the active form.
- 19. The fusion of a male gamete and female gamete to form a diploid zygote.
- 20. A method of rapidly cloning large numbers of plants using explants and tissue culture.
- 23. A plant hormone that promotes root formation and bud growth
- 24. Embryo shoot
- 26. An isotope that has an unstable nucleus and undergoes radioactive decay
- 28. An attraction between molecules of different substances
- 32. Found in phloem; stacked end to end; have holes so materials can get in and out of the phloem
- 37. Attraction between molecules of the same substance
