Current Question (ID: 12493)

Question:

All the tissues that lie inner to the endodermis are called as

Options:

1. vascular bundle
2. stele
3. pith
4. cork cambium

Solution:

In plant roots, the stele refers to the central cylinder of vascular tissue that includes the pericycle, endodermis, and vascular bundles. The tissues that lie inside the endodermis, which is the innermost layer of the cortex in roots, are collectively referred to as the stele. These tissues are involved in the transport of water, minerals, and nutrients within the plant root. The pith is the central region of parenchyma cells in a stem, and the cork cambium is a meristematic tissue responsible for the formation of the cork layer in plant stems and roots. Vascular bundles are clusters of vascular tissue scattered throughout the ground tissue of stems and roots, and they are part of the stele.
