Parenchyma cells are
(a) relatively unspecified and thin walled
(b) thick walled and specialised
(c) lignified
(d) none of these

Answers (1)

Parenchyma is a type of simple permanent tissue. It forms the bulk of the plant body. It is made up of living cells that are unspecialized and have thin cell walls. The cells are loosely arranged, thus large spaces between cells (intercellular spaces) are found in this tissue. It is the most abundant and versatile tissue in plants, performing various essential functions depending on its location and specialization.

Explanation for Incorrect Options:

  • (b) Thick-walled and specialized:
    This describes sclerenchyma cells, not parenchyma. Sclerenchyma cells have thick, lignified walls for mechanical support.

  • (c) Lignified:
    Parenchyma cells are non-lignified, whereas lignification is a characteristic of sclerenchyma and some xylem cells.

  • (d) None of these:
    Incorrect, as an option (a) accurately describes parenchyma cells.

The correct option is – (a)- relatively unspecified and thin-walled.
