Question

Synthesis of cell wall material takes place in:
A. Dictyosomes
B. Mitochondria
C. Lysosomes
D. E.R

Answer 1

Hint: The cell wall is the main pressure bearing and shape maintaining component in bacteria, and its respectability is of basic significance to cell viability. In both gram-positive and gram-negative microorganisms, the framework of the cell wall comprises the cross-linked polymer peptidoglycan (PG).

Complete Answer:
- Golgi apparatus is a complex organelle composed of layer lined stack of cisternae, organization of tubules, vesicles and vacuoles. Golgi apparatus is present in all eukaryotic cells aside from RBC and sieve tube elements. The Golgi apparatus is not associated with the ER, yet ER-determined, membrane bound vesicles convey materials from the ER to the Golgi apparatus. Fundamentally, the Golgi apparatus comprises a heap of four to six sacs, called cisternae, encompassed by vesicles. The stack of cisternae is called the Dictyosome.

- Proteins are put away in the dictyosomes for transport, modified, arranged, and packed into vesicles. Membrane bound vesicles got from the ER fuse with one of the dictyosome cisternae known as the forming face. Materials conveyed by these vesicles are prepared inside the dictyosome cisternae.

- At last, vesicles that are squeezed from the maturing face of the dictyosome are transported to the plasma membrane or to another membrane bound compartment, for example, the vacuole. This is the way taken by cell wall proteins, for example, extension and some seed storage proteins. The dictyosomes are occupied with secretory activities (because secretory materials are delivered in dictyosomes) and fast divisions (since wall materials are synthesized in dictyosomes).
- The Golgi device assumes a significant part in the synthesis of cell wall polysaccharides.

Hence, the correct answer for this A, i.e. Dictyosomes.

Note: The number or quantity of golgi bodies or dictyosomes is commonly 9 to 10 in a plant cell however is extremely high in cells occupied with secretory activities, e.g., root cap cells they produce mucilage and in cells occupied with rapid division for creation of wall.
