| What chromosome set is characteristic of the cells of the root division zone and the ovule megaspore of a flowering plant, from which an eight-nucleated embryo sac develops? Explain from what initial cells and as a result of what division these cells are formed.
1) the set of chromosomes of the cell of the root division zone – 2n; megaspores ovule – n; 2) root cells develop from an embryo (zygote) by mitosis; 3) megaspore is formed as a result of meiosis from the ovule cell in the pistil ovary.
