parenchyma cell
Quick Summary
Parenchyma cells are a fundamental type of plant tissue. These cells are characterized by their thin walls and unspecialized structure, making them highly adaptable to various functions. They are living cells actively involved in processes such as photosynthesis, secretion, and food storage.1
Parenchyma tissue is found throughout plant bodies, forming the mesophyll of leaves, the cortex and pith of stems and roots, and the soft tissues of fruits. They are also present in xylem and phloem. Unlike sclerenchyma (dead, thick-walled tissue) and collenchyma (living, irregularly walled tissue), parenchyma cells are versatile and can differentiate to perform specialized roles. Chloroplasts, essential for photosynthesis, are particularly concentrated within parenchyma cells in plant leaves.123

angiospermGround tissue…composed of relatively simple, undifferentiated parenchyma cells. In most plants, metabolic activity (such as respiration, digestion, and photosynthesis) occurs in these cells because they, unlike many of the other types of cells in the plant body, retain their protoplasts (the cytoplasm, nucleus, and cell organelles) that carry out these functions.
