Parenchyma meaning

A soft tissue made up of thin-walled, undifferentiated living cells with air spaces between them, constituting the chief substance of plant leaves and roots, the pulp of fruits, the central portion of stems, etc.

The tissue characteristic of an organ, as distinguished from associated connective or supporting tissues.

A simple plant tissue, composed of thin-walled cells and forming the greater part of leaves, roots, the pulp of fruit, and the pith of stems.

The essential or functional tissue of an organ, as distinguished from its connective tissue, blood vessels, etc.

A spongy mass of tissue packing the spaces between the organs of some invertebrates.

The tissue characteristic of an organ, as distinguished from associated connective or supporting tissues.

A simple plant tissue, composed of thin-walled cells and forming the greater part of leaves, roots, the pulp of fruit, and the pith of stems.

The basic tissue of plants, consisting of cells with thin cellulose walls. The cortex and pith of the stem, the internal layers of leaves, and the soft parts of fruits are made of parenchyma. In contrast to sclerenchyma cells, parenchyma cells remain alive at maturity. They perform various functions, such as water storage, replacement of damaged tissue, and physical support of plant structures. Chloroplasts, the organelles in which photosynthesis takes place, are found in parenchyma cells.

Parenchyma is defined as the functional part of organ tissue, or tissue found in the soft parts of plants and fruits.
