Across
  1. 4. The first leaves that can be observed from a germinating seed
  2. 7. A stem found below the cotyledons and above the root
  3. 9. Growth in presence of light short and green
  4. 12. The development of a seedling in the presence of light
  5. 17. Group of cells that gives rise to leaves
  6. 19. Found in the growing tips of roots and shoots in plants that consists of actively dividing cells
  7. 21. The developed upper cells in a zygote
  8. 22. A group of cells that is made along with the embryo and through elongation carries the embryo towards its food source
  9. 25. Process of cell division that results in four haploid daughter cells
