A secretory granule is the place where secretions are stored. Secretory granules are also an important component of the secretion process.

peptide hormones and catecholamines (epinephrine and norepinephrine)
This process is called holocrine secretion, where the entire cell containing the secretory product ruptures to release its contents. This differs from merocrine secretion, where secretory products are released through exocytosis without cell damage.
Secretory vesicles pinch off from the Golgi apparatus during the process of exocytosis. These vesicles contain proteins or other molecules destined to be secreted from the cell. Once they pinch off, they move towards the cell membrane to release their contents outside the cell.
This is the IB answer key to this Question: secretory cells arranged in layer one cell thick; cells contain secretory vesicles; cells are grouped in acini; surrounded by basement membrane; cells adjacent to duct/lumen;

An adenocyte is a secretory cell of a gland.
They mostly secrete proteins...
Secretory vesicles can form from the Golgi apparatus, which packages proteins and molecules for secretion. These vesicles can also be formed from endosomes that have internalized molecules or from specialized secretory cells in the body. Once formed, secretory vesicles move towards the cell membrane for exocytosis to release their contents outside the cell.
The three features that a plant cell has that an animal cell does not have are cell wall, chloroplasts and vacule
Golgi Apparatus
Vesicles perform many functions through complex mechanisms that can involve many aspects of cell regulation. Secretory vesicles in particular are specialized vesicles formed in the trans-golgi apparatus for releasing a product (such as molecule or protein) outside the cell. Secretory vesicles are used for exocytosis. Mast cells use secretory vesicles to release histamine which is a molecule involved immune response. Neurotransmitters can also be transmitted in secretory vesicles from nerve cells.

Golgi body is a cell organell, which is a centre for dipatchment of secretory products
This process is called holocrine secretion, where the entire cell containing the secretory product ruptures to release its contents. This differs from merocrine secretion, where secretory products are released through exocytosis without cell damage.
