Tissue that makes up the majority of a plant
A
vascular tissue
B
ground tissue
C
dermal tissue
D
None of the above
Explanation: 

Detailed explanation-1: -They are located between dermal and vascular tissue . The ground tissue comprises Parenchyma, Collenchyma, and Sclerenchyma cells. Parenchyma cells make up the majority of ground tissue.

Detailed explanation-2: -Cells in ground tissue Ground tissue cells include parenchyma, (photosynthesis in the leaves, and storage in the roots), collenchyma (shoot support in areas of active growth), and schlerenchyma (shoot support in areas where growth has ceased). Parenchyma are the most abundant and versatile cell type in plants.

Detailed explanation-3: -The ground tissue system arises from a ground tissue meristem and consists of three simple tissues: parenchyma, collenchyma, and sclerenchyma (Figure 5).

Detailed explanation-4: -Parenchyma. Parenchyma is a versatile ground tissue that generally constitutes the “filler” tissue in soft parts of plants. It forms, among other things, the cortex (outer region) and pith (central region) of stems, the cortex of roots, the mesophyll of leaves, the pulp of fruits, and the endosperm of seeds.
