Question

The main function of dictyosomes is
A. Respiration
B. Storage
C. Secretion
D. Breakdown of Fats

Answer 1

Hint: Dictyosomes, which form the Golgi apparatus, are net-like flat, membrane-bound cavity structures called cisternae. At the intersection of the secretory, lysosomal, and endocytic pathways, it persists. In processing proteins, it is of special importance.

Complete answer:
Dictyosomes refer to stacks of flat cisterns linked to the membrane that together form the Golgi apparatus.
The Golgi apparatus consists of a set of compartments in most eukaryotes and is a collection of fused, flattened membrane-enclosed discs known as cisternae, also known as dictyosomes, which derive from vesicular clusters budding from the endoplasmic reticulum. In a mammalian cell, there are normally 40 to 100 stacks of cisternae. There are usually between four and eight cisternae present in a stack, but some protists have found as many as sixty cisternae.
They contain proteins that are processed, modified, sorted and packed into vesicles from the Golgi bodies that pinch off. Plant cells usually contain smaller vesicles of the Golgi apparatus type, which are called dictyosomes.
Secretion is the primary feature of dictyosomes.
So, the correct answer is “Option C”.

Note:
Each cistern stack has a cis entry face and a Trans exit face in all eukaryotes. There are assortments of enzymes inside individual stacks responsible for selectively altering the shipment of protein. These changes affect the protein’s fate. In order to isolate enzymes, the compartmentalization of the Golgi apparatus is beneficial, thus preserving sequential and selective processing steps: enzymes catalyzing early on modifications are collected in the cis face cisternae, and enzymes catalyzing later alterations are found in Trans face cisternae of the Golgi stacks.
