Botany - Anatomy of Flowering Plants Question with Solution | TestHub
Read the following statements about the living plant tissue which has irregular thickenings and identify the false statement.
I. The cell wall is rigid without any intercellular spaces.
II. It is found in the form of a single-layered hypodermis of the herbaceous dicotyledonous stem.
III. It is mostly found in monocots and roots.
IV. The main function is to provide flexible mechanical support and tensile strength.
Options:
Answer:
Solution:
The living plant tissue which has irregular thickenings is called collenchyma. The thickenings are made up of pectin between the cells. Thus there is no free intercellular space. In a dicot stem, the hypodermis, consists of a few layers of collenchymatous cells and it provides mechanical strength to the young stem. In monocot stem the hypodermis is sclerenchymatous. It is absent in roots.
