cells and chloroplast


Again, your explanation is too simple.  First we are only interested in what
leads to an unstable meristem, the other cells are unimportant.  We have
been informed by Jim H. that the meristem forms early in cell division, so
what ever happens, it must happen early.  Now a streaked plant has two types
of cells, a white cell and a green one.  The egg comes from only one cell, a
white one or a green one (from the streaked maternal parent).  So where are
the two types of chloroplasts to randomly sort into daughter cells?  Streaks
would imply a continuous process of sorting, How does this happen?

Pollen dont containchloroplast in Hosta. If the egg is made in a streaked plant part of the chloroplast are mutated. A fertilized egg(a zygote), when ....
