Question

16 mitosis ensures that the hereditary blueprint for cellular protein production is transmitted to the next generation of cells.
17 in plants the cell plate forms within the phragmoplast.
18 during cytokinesis, the cell walls of the daughter cells form from the cell wall of the parent cell.
19 all multicellular organisms produce new individuals by mitosis.
20 every organism has chromosome number characteristic of its particular species.
21 a cell that has more then two sets of chromosomes is said to be diploid.

Explanation:

1. Mitosis replicates and distributes DNA, ensuring genetic continuity for protein - production instructions. True.
2. In plant cell division, the cell plate forms within the phragmoplast. True.
3. During cytokinesis in plants, the cell walls of daughter cells form from the cell plate, not directly from the parent - cell wall. False.
4. Multicellular organisms use meiosis for sexual reproduction and mitosis for growth and repair, not all new individuals are produced by mitosis. False.
5. Each species has a characteristic chromosome number. True.
6. A diploid cell has two sets of chromosomes, a cell with more than two sets is polyploid. False.
