WRITE ABOUT A THEME: ORGANIZATION Cells arc the basic units of structure and function in all organisms. A key feature in the life cycle of plants is the alternation of multicellular haploid and diploid generations. Imagine a lineage of flowering plants in which mitotic cell division did not occur between the events of meiosis and fertilization (se Figure 30.12). In a Short essay (lOO-150 words), describe how this change in the timing of cell division would affect the structure and lifecycle of plants in this lincagc.
