Question

1. A layer of cells called the endodermis surrounds the stele. Xylem is found towards the center of the stele and phloem towards the outside of the stele. How does this compare to their arrangement in the stem? 2. The meristematic region is protected in the root by the presence of a root cap. How is the meristematic region protected in the stem tip? In which of these regions would you expect to find the specialized cells of vascular tissue? In which of these regions are the cells genetically identical? Why?

Answer 1

1. How does this compare to their arrangement in the stem?The xylem and the phloem in the stem are being separated by a vascular cambium which is not surrounded by a endodermis.
2.How is the meristematic region protected in the stem tip? In which of these regions would you expect to find the specialized cells of vascular tissue? In which of these regions are the cells genetically identical?This region in the stem is protected by leaves called scales. In the meristem tissue, mitosis happens where cells are divided.

Answer 2

Xylem is found toward the center of the vascular bundle and phloem toward the outside of the stele. How does this compare to their arrangement in the stem?
Answer : Xylem and phloem are separated by a layer of vascular cambium (not surrounded by a layer of endodermis)

The meristematic region is protected in the root by the presence of a root cap. How is the meristematic region protected in the stem tip?
Answer : it is Covered with protective leaves called scales.

In which of these regions would you expect to find the specialized cells of vascular tissue? In which of these regions are the cells genetically identical? Why?
Answer : In meristem tissue, the cells divide by mitosis. This is where genetically identical copies of the parent cell is prodused. Therefore all the cells must be genetically identical
