- Understand the structure of DNA.
- Compare the different states of ploidy and which process of cell division — mitosis or meiosis — they are produced from.
- Recognize what happens to the chromosomes, cell wall, cell membrane, and nuclear membrane in each of the stages of mitosis and meiosis.
- Compare the similarities and differences in the outcomes of mitosis and meiosis.
Mitosis is essential to all plant propagation. It produces the mighty oak from a single zygote cell and makes all forms of propagation possible. The adventitious rooting process of any cutting begins with mitosis and continues through many mitotic divisions to produce a root meristem. Meiosis is also fundamental to plant propagation for the production of gametes that fuse, producing diversity for evolution and plant breeding.
