Also, in plant cells, they are distributed throughout the cytoplasm and are called dictyosomes.

Functions:

1. It is involved in the transport and modification of protein, lipids as well as carbohydrates.

2. It helps in the formation of cell plate during cell division.

3. It is also involved in the formation of cell wall, plasma membrane lysosomes and peroxisomes.

4. The material synthesised near endoplasmic reticulum is packaged and dispatched to various targets and outside the cell through the Golgi apparatus.
