Golgi apparatus or Golgi complex or Golgi bodies
<h3><u>Explanation;</u></h3>
- <u><em>Golgi apparatus are also called Golgi bodies or Golgi complex. They are complex vesicles and folded membrane within the cytoplasm of eukaryotic cells.</em></u>
- <em><u>Golgi apparatus are important in the secretion and intracellular transport roles. A major function is the modifying, sorting and packaging of proteins for secretion. T</u></em><em><u>hey are also involved in the transport of lipids around the cell, and the creation of lysosomes.</u></em>
- Therefore, <u><em>Golgi apparatus are the organelles responsible for the formation of lysosomes, which are organelles that destroy old and worn out cellular organelles. </em></u>

Peyer's patches (aggregated lymphoid nodules)
Explanation:
Peyer's patches are anatomical regions located under the mucosa of the gastrointestinal tract, specifically in the lamina propria of the thin intestine. These patches are nodules or cumulus of lymphatic tissue and other accessory cells, and this is why they represent a huge part of the mucosa´s immunity system.
Peyer's patches belong to the group of lymphoid tissue associated with the intestine, composed of lymphoid follicles distributed along the gastrointestinal tract.
A lymphoid follicle is a cumulus or aggregate of lymphoid cells that do not have a well-defined structure nor organization. In general, these follicles are isolated from each other in the intestine. But in the terminal ileum (The last portion of the thin intestine) they get so close that they might form a plaque. The Peyer´s patches are formed principally by lymphocytes B that synthesize immunoglobulin A, which has an important role in immunity.
