Answer 1

The correct option is A all tissues except epidermis and vascular tissues

Ground tissue system refers to all the tissues that are present inside the plant body except epidermis and vascular system. It constitutes the main bulk of the plant body. Ground tissues include various simple tissues like parenchyma, collenchyma and sclerenchyma.

In leaves, the ground tissue is called mesophyll.
In the monocot stem, the ground tissue consists of hypodermis and parenchyma cells.
In dicot stem and all angiospermic roots, the ground tissue consists of the cortex (hypodermis, general cortex and endodermis), pericycle and pith.
