A–H, Pinus sp. e. Specialized parenchyma cells. Parenchyma cells are specialized plant cells that can grow and reproduce throughout the life of the plant. Numbers 1–8 are classified as late phloem in the study. The lining of the cyst is flat or may have small papillary projections. Answer: Parenchyma cells are thin walled, unspecialized in structure. Its cells are living and they possess the power of division. Sol.

They have two functions, storage and lateral food conduction. The remaining renal parenchyma has been reduced to a thin shell of dense fibrous connective tissue, rare sclerotic glomeruli and moderate numbers of mixed inflammatory cells.

The parenchyma is the simplest among the three types of plant cells because they only have a very thin layer of cell walls. ... a ground tissue composed of chloroplast-rich parenchyma cells. 22, 25 Immunoglobulin heavy chain gene rearrangement or evidence of t(14;18) breakpoints is not observed. a relatively unspecified plant cell type that carries out most of the metabolism, synthesizes and stores organic products, and develops into a more differentiated cell type. Relatively unspecified and thin walled. Parenchyma cells are (a) relatively unspecified and thin walled (b) thick walled and specialised (c) lignified (c) none of these. Question 29.
