Explanation / Answer
1. Meiosis and mitosis differ in that e. mitosis produces only body cells Reason- germ cells are produced only by meosis. 2. Most of the growth of the plant body is the result of e. cell enlargement Reason - morphogenesis (shape), embryogenesis (development), differentiation (types of cells), and cell division (divides cell). so growth is due to cell enlargement. 3. Onion meristematic cells contain 16 chromosomes. Number of chromosomes found in a mature stem parenchyma cell c.16 Reason - both cells are normal cells with chromosome condition as haploid. 4. In the process of stomatal opening, the _outer___ walls of the guard cells__move outward ___ relative to their common walls. Reason - extra turgor pressure elongate the guard cells, and ends are held firmly in place by surrounding epidermal cells, the two guard cells lengthen by bowing apart from one another, creating an open pore through which gas can move.
