Difference between parenchyma and prosenchyma cells?
Answers
Explanation:
What is Parenchyma?
Parenchyma is the simplest tissue in plant body that characterized by the presence of uniformly thin primary cell wall and lack of secondary cell wall. The primary cell wall is permeable to small molecules that enable many metabolic functions by allowing materials to move inside the cell and expelling chemically altered substances from the cell body. These cells are often called chlorenchyma due to the ability of photosynthesis, the process during which water, carbon dioxide, and light enter the cell easily to produce sugars, which use as the energy source in plants. Additionally, parenchyma cells are adapted to store certain substances in plants. For example, parenchyma cells act as starch storage cells in seeds and tubers. Moreover, they store oils (avocado, sunflower), water (cacti) and pigments (fruits, flower petals) in certain plant species. Most importantly parenchyma cells make the meristematic tissue, which carries out plant growth.
What is Prosenchyma?
Prosenchyma is a plant tissue that consists of elongate cells with tapering ends (unlike parenchyma cells); prosenchyma cells vary in origin and function. There are transitional types of tissue between prosenchyma and parenchyma, for example, collenchyma or the lobate branched cells of mesophyll in the leaves of canna and other plants.
