Collenchyma is simple living tissue with thick non-lignified walls and uneven deposition of cellulose and pectin. They are derived from parenchyma and are present in groups under epidermis to provide flexible support to the growing plant's organs and thus are present in young dicot stem, pedicel, and petioles, not in leaf base and roots, which are not the growing part. It is not present in monocots.

Collenchyma is mainly present in stems, leaves, floral parts and is the main supporting tissue in many mature eudicot leaves and some green stems roots rarely have collenchyma but collenchyma may occur in the cortex of root if the root is exposed to light collenchyma is absent in monocots and roots due to early development of schlerenchyma .Schlerenchyma provide mechanically strength to plant so there will be no any need for development of collenchyma

Which of the following plant organs do not contain collenchymaa)Leaf b...
Explanation:
Collenchyma is a type of simple permanent tissue that provides mechanical support and elasticity to the plant. It is characterized by its living cells with thickened cell walls. Collenchyma cells are usually found in young, growing parts of the plant, such as leaf bases, stems, and roots.
Leaf bases:
Collenchyma cells are present in the leaf bases. The leaf base is the part of the leaf that attaches it to the stem. It provides support and flexibility to the leaf, allowing it to withstand wind and other external forces.
Monocot stem:
Collenchyma cells are also present in the stem of monocot plants. Monocots are a type of flowering plant that has one cotyledon (seed leaf) in its embryo. The stem of monocots contains vascular bundles scattered throughout the ground tissue. The ground tissue includes collenchyma cells, which provide mechanical support to the stem.
Roots:
Collenchyma cells are also found in the roots of plants. The roots anchor the plant to the ground and absorb water and nutrients from the soil. Collenchyma cells in the roots provide structural support and help in maintaining the shape and integrity of the root system.
All of the above:
Based on the information provided, all the given plant organs (leaf bases, monocot stem, and roots) contain collenchyma cells. Therefore, option 'D' is the correct answer.
