Detailed explanation-1: -In plant cells, the Golgi apparatus participates in the secretion of a variety of extracellular materials, including fucose-rich mucilage by root cap cells, wall-degrading enzymes during abscission, hydrolases that degrade the food reserves during germination, and digestive enzymes in insectivorous plants.

Detailed explanation-2: -The Golgi apparatus is responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations. As the secretory proteins move through the Golgi apparatus, a number of chemical modifications may transpire.

Detailed explanation-3: -Secretory vesicles form from the trans Golgi network, and they release their contents to the cell exterior by exocytosis in response to extracellular signals. The secreted product can be either a small molecule (such as histamine) or a protein (such as a hormone or digestive enzyme).

Detailed explanation-4: -Lysosomes are vesicles that are formed by the Golgi apparatus. They contain powerful enzymes that could break down (digest) the cell. Lysosomes break down harmful cell products, waste materials, and cellular debris and then force them out of the cell. They also digest invading organisms such as bacteria.
