fundamental tissue
Quick Summary
Fundamental tissue in plants, also known as ground tissue, is distinct from dermal and vascular tissues. It is typically composed of relatively undifferentiated parenchyma and supportive cells.1
Parenchyma cells are living, thin-walled, and adaptable, performing functions like photosynthesis, secretion, and food storage. They are found in leaves, stems, roots, and fruits.2
Collenchyma tissue consists of living, elongated cells with unevenly thickened walls, providing support, especially in areas of primary growth. Sclerenchyma tissue is composed of hard, woody cells, often dead at maturity, with heavily thickened, lignified secondary walls that provide rigid support. These three types—parenchyma, collenchyma, and sclerenchyma—are the primary types of plant cells.345

Ground tissue called the cortex surrounds the vascular cylinder and pericycle. The cortex of roots generally consists of parenchyma cells with large intercellular air spaces. The endodermis (the innermost layer of the cortex adjacent to the pericycle) is composed of closely packed cells that have…
