Expert Answer:

1. Prosenchyma: Prosenchyma is a plant tissue that consists of elongated cells with interpenetrating tapering ends, that occurs especially in vascular tissue. Prosenchyma cells are starch-containing parenchymal cells whose cell walls have become lined with lignin. These type of cells are present in the stems of Bougainvillea (Nyctaginaceae).

2. Periderm: Periderm is the secondary protective (dermal) tissue that replaces the epidermis during growth in thickness of stems and roots of gymnosperms and dicotyledons (secondary growth). Periderm is composed of  phellogen, phellem, and phelloderm.

3. Trichome: Trichomes are fine outgrowths or appendages found on plants and some protists. They can be of many types, which include unicellular, multicellular and glandular hairs and scales found on various parts of the plant.

4. Ranunculus: Ranunculus is a temperate plant of a family Ranunculaceae that includes buttercups and water crowfoots, typically having yellow or white bowl-shaped flowers and lobed or toothed leaves.
