Organismal Development Part 2

Explore the life cycles of haploid and diploid multicellular organisms in fungi and plants. Learn about gametes, mitosis, meiosis, fertilization, spores, and the alternation of generations. Witness the magic of plant grafting and the growth process from callus to entire plant.

  10. . Just a few parenchyma cells from a carrot gave rise to this callus, a mass of undifferentiated cells. The callus differentiates into an entire plant, with leaves, stems, and roots.
