Question

In a woody dicotyledonous tree, which of the following parts will mainly consist of primary tissues:

• A. Stem and root
• B. All parts
• C. Branches
• D. Flowers, fruit and leaves

Answer 1

The correct option is D Flowers, fruit and leaves

The increase in the girth of the stem and the root in a dicot plant by the activity of lateral meristems is called secondary growth. The tissues produced by secondary growth are called secondary tissues. The remaining tissues are called primary tissues.
A dicot stem and root undergo secondary growth and hence have some secondary tissues. Branches of a dicot tree also show some secondary growth. Flowers, fruits and leaves are all made of primary tissues and hence are the answer.
