Question

Answer

In a woody dicotyledonous tree, shoot tips and root tips parts are mainly consists of primary tissues.

Answer

RAM and SAM
means root apical meristem and shoot apical meristem consist of primary tissue

Answer

Correct answer is option.C

Answer

The correct answer is option 'C', which means that shoot tips and root tips mainly consist of primary tissues in a woody dicotyledonous tree.

Primary tissues in plants are the tissues that are derived from the apical meristems, which are located at the tips of the shoots and roots. These meristems are responsible for the primary growth of the plant, resulting in the elongation of the stems and roots.

Shoot tips:
When a woody dicotyledonous tree is young, its shoot tips primarily consist of primary tissues. The apical meristem at the shoot tip gives rise to the primary tissues that make up the stem, leaves, and flowers. The primary tissues in the shoot tip include the protoderm, ground meristem, and procambium.

Root tips:
Similarly, the root tips of a woody dicotyledonous tree also mainly consist of primary tissues. The apical meristem at the root tip is responsible for the primary growth of the root, resulting in the elongation of the root. The primary tissues in the root tip include the protoderm, ground meristem, and procambium.

Primary tissues in other parts:
While the stem, root, flowers, fruits, and leaves of a woody dicotyledonous tree do contain primary tissues, they also contain secondary tissues. Secondary growth occurs in these parts of the plant, resulting in an increase in girth or thickness. Secondary tissues, such as secondary xylem and phloem, are produced by the vascular cambium, which is a secondary meristem. These secondary tissues are responsible for providing structural support and transporting water, nutrients, and sugars throughout the plant.

In conclusion, while all parts of a woody dicotyledonous tree do contain primary tissues, the shoot tips and root tips mainly consist of primary tissues. These tissues are derived from the apical meristems and are responsible for the primary growth of the plant.
