Across
  1. 5. promotes senescence of leaves and fruit, is involved in bud & seed dormancy, helps with stomatal opening and closing, signals plants of physiological stress, and protects plants from environmental conditions
  2. 6. outermost appendages of the flower, modified leaves, enclose to protect the flower at bud stage, collectively known as the calyx
  3. 7. Development of seeds with no fusion of the gametes/without fertilisation
  4. 8. contains the stigma, style and ovary (female flower parts)
  5. 11. form of reproduction which results in progeny that is genetically identical to the parent
  6. 12. involved in cell division, inhibit senescence (death), produced in root tips, high concentration in fruits and seeds
  7. 13. true flowering plants
  8. 15. plants response to day length
  9. 17. produced in the shoot apex, involved in geotropism/gravitropism, phototropism, cell division, and enlargement
  10. 18. programmed physiological process in which prolonged cold exposure provides competency to flower in plants
Down
  1. 1. division of the nucleus into four cells with half the chromosome number of the original cell
  2. 2. can be bound or free, cell division and elongation in internodes, dormancy break in seeds and buds, balance between juvenile and adult forms, onset of flowering in place of vernalisation.
  3. 3. found in monocot flowers, where the sepals and petals are similar and fused at the base
  4. 4. Development of seedless fruit
  5. 6. contains the anther and filament (male flower parts)
  6. 9. Fruit that continue to ripen after harvesting
  7. 10. division of the nucleus to produce two daughter nuclei containing identical sets of chromosomes
  8. 14. Chemical which ripens fruit
  9. 16. form of reproduction which results in progeny that are genetically diverse
