Answer:

Plants have three basic types of tissues: The fundamental tissues are the plant tissues responsible for nutrition. They are found in all plant organs and are made up of living cells with large vacuoles. The epidermal tissue is the one that covers the roots, stems, leaves and other organs of plants. It is a thick layer with flattened and attached cells. It is lined with a wax-like lipid-rich cuticle that prevents water loss. Conductive tissues make up the vascular system of the plant. They are made up of specialized transfer cells.

Step-by-step explanation:

The fundamental tissue comprises the main part of the body of the plant. Parenchymal cells (the most abundant), cholenchymal and sclerenchymal cells constitute the fundamental tissues. The cells of the parenchyma located in leaves, stem and root; responsible for photosynthesis or storing substances. Collenchyma cells also form this type of tissue, and their function is to support the stems of herbaceous plants. Sclerenchyma cells have cellulose primary and secondary walls, providing great rigidity and firmness, which is why it is only found in woody plants.The epidermal tissue covers the external surfaces of herbaceous plants, it is composed of tightly united epidermal cells that secrete a layer formed by cutin and waxes called cuticle that prevents the loss of water. Stomata, trichomes and other types of specializations can be seen in it.Vascular tissue, xylem and phloem, are made up of parenchymal cells that store food and water, as well as conduction cells and supporting fibers. Phloem conduction cells transport the products of photosynthesis, mainly sucrose, from leaves to non-photosynthetic cells; xylem cells carry water and minerals from the roots to other parts of the plant.
