Detailed explanation-1: -Vascular tissue cells: Tracheids. Vessel elements. Sieve tube cells. Companion cells. Dermal tissue cells: Epidermal cells. Stomata or more accurately, guard cells. Trichomes. Ground tissue cells: Parenchyma. Collenchyma. Sclerenchyma.
Detailed explanation-2: -plant tissue Primary dermal tissues, called epidermis, make up the outer layer of all plant organs (e.g., stems, roots, leaves, flowers). They help deter excess water loss and invasion by insects and microorganisms.
Detailed explanation-3: -Dermal tissue refers to the plant epidermis, the outer layer of tissue that surrounds the primary body of vascular plants. This includes the roots, stems, leaves, flowers, fruits, and seeds. The dermal layer does not contain chloroplasts and is typically composed of a single layer of tightly-packed cells.
