All tissues except epidermis and vascular bundles constitute the ground tissue. It consists of simple tissues such as parenchyma, collenchyma and sclerenchyma. Parenchymatous cells are usually present in cortex, pericycle, pith and medullary rays, in the primary stems and roots. In leaves, the ground tissue consists of thin-walled chloroplast containing cells and is called mesophyll.
Consider the following statements regarding plant tissue systems: 1. All tissues except epidermis and vascular bundles constitute the ground tissue system. 2. Parenchymatous cells of ground tissue are found in cortex, pericycle, pith, and medullary rays. 3. In leaves, the ground tissue is called mesophyll and consists of chloroplast-containing thin-walled cells. 4. Vascular bundles with cambium present (as in dicot stems) are closed and cannot form secondary tissues. 5. In roots, the vascular bundle arrangement is radial, while in stems and leaves it is commonly conjoint. Which of the above statements are correct?
