Explain briefly the mechanism of secondary growth of dicot stem |
| Answer» In botany,\xa0secondary growth\xa0is the\xa0growth\xa0that results from cell division in the cambia or lateral meristems and that causes the\xa0stems\xa0and roots to thicken, while primary\xa0growth\xa0is\xa0growth\xa0that occurs as a result of cell division at the tips of\xa0stems\xa0and roots, causing them to elongate, and gives rise to primary tissue. Secondary growth\xa0is the formation of\xa0secondary\xa0tissues from lateral meristems. It increases the diameter of the\xa0stem. In woody plants,\xa0secondary\xa0tissues constitute the bulk of the plant. They take part in providing protection, support and conduction of water and nutrients. | |
