Question

describe briefly the formation of secondary tissues in dicots

Answer 1

Answer:

DON'T FORGET TO LIKE

Explanation:

Secondary growth is the formation of secondary tissues from lateral meristems. It increases the diameter of the stem. In woody plants, secondary tissues constitute the bulk of the plant.

In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate, and gives rise to primary tissue. Secondary growth occurs in most seed plants, but monocots usually lack secondary growth. If they do have secondary growth, it differs from the typical pattern of other seed plants.

The formation of secondary vascular tissues from the cambium is a characteristic feature of dicotyledons and gymnosperms. In certain monocots, the vascular tissues are also increased after the primary growth is completed but the cambium of these plants is of a different nature. In the living Pteridophytes this feature is rare but occurs in plants like Isoetes and Botrychium.

Answer 2

It increases the diameter of the stem. In Woody plants, secondary tissue constitute the bulk of the plant. They take part in providing protection, support and conduction of water and nutrients.tissue are formed by 2 types of lateral meristems.....
