Answers (1)
Pericycle:
- It is present between the endodermis and vascular bundles.
- It can be one or several layered.
- It is the outermost layer of the stele.
- Hence, it is an intrastellar tissue.
- In all roots, it is homogeneous and parenchymatous.
- In dicot stem, it is heterogeneous and can be parenchymatous and sclerenchymatous.
- In monocots, it is sclerenchymatous.
- It is absent in the roots and stems of aquatic and parasitic plants.
- In pteridophytes, it is single-layered.
- In gymnosperms, it is multi-layered.
- In angiosperms, it is 2 - 3 layered.
- Pericycle gives rise to secondary meristem during secondary growth.
- In roots, it gives rise to lateral roots. It is called pericambium in this condition.
- The lateral roots are therefore known to have an endogenous origin.
TIP: All tissues on the inner side of the endodermis such as pericycle, vascular bundles and pith constitute the stele.
Pericycle is absent in aquatic plants.
