Give one function of the following:
a. Parenchyma
b. Aerenchyma
c. Collenchyma
d. Apical meristem
Answers
a)Parenchyma forms the bulk of plant ground tissue, where they may be specialised to function in photosynthesis, storage, or transport. Parenchyma is integral to vascular tissue, where it provides a route of exchange for materials within and between the xylem and the phloem.
b)Aerenchyma is a spongy tissue that forms spaces or air channels in the leaves, stems and roots of some plants, which allows exchange of gases between the shoot and the root.
c)The chlorenchyma are parenchymal cells that contain chloroplasts. The chlorenchyma hence serve as the cells that support photosynthesis. In these cells synthesis of carbohydrate is at its maximum, including the pallisade cells, for distribution around the plant.
d)Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots. Lateral meristems are known as secondary meristems because they are responsible for secondary growth, or increase in stem girth and thickness.
