Question

Isolated units of Golgi apparatus found in plant cells are called
A. Golgisomes
B. Dictyosomes
C. Lipochondria
D. Cisternae

Answer 1

Hint: A Golgi apparatus is a complex of vesicles and folded membrane within the cytoplasm of the eukaryotic cells. They are involved in the secretion and intracellular transport.

Complete Answer:
- The Golgi apparatus is a membrane bound organelle seen in most cells. It is dependable for packaging proteins into vesicles former to secretion and as a result plays a key role in the secretory pathway.
- The Golgi apparatus are made of 5 to 8 folds called cisternae. The cisternae hold specific enzymes creating five functional regions which modify proteins passing through them in a stereotypical way
- The Golgi apparatus gives modification to proteins and lipids that is received from the endoplasmic reticulum. These biochemicals depart the Golgi by exocytosis before being delivered to different intracellular or the extracellular targets.
- Dictyosome composed of flattened membranous sacs. They seem to be like a stack of pita bread. A cell might have several interconnected stacks. Each cisterna in a mass consists of a membrane. This membrane separates its inner space from the cytosol. They are used in the movement of material between the Golgi and other structures. The amount of dictyosomes may be a few hundred in plant cells. But in lower organisms they have only four or less dictyosomes.
- Golgi apparatus is a midpoint of manufacturing, storing, and transportation. At this point products are modified and then sent to further parts. The Golgi apparatus are broad in cells specialized for secretion.
- Isolated units of Golgi apparatus seen in plant cells are called dictyosomes. Dictyosomes refers to stacks of flat, membrane bound cisternae which collectively forms the Golgi apparatus. Dictyosomes in plant cells are detached in the fluid matrix of the cell called cytoplasm. They are composed of proteins which are stored, modified, sorted and packed into vesicles that bit off from the Golgi bodies.

The correct answer for this question is option B) Dictyosomes.

Note: The important function of dictyosome is secretion. They are generally known as the isolated units of Golgi apparatus which are found in plant cells.
