Goblet and secretory cells. Coloured transmission electron micrograph (TEM) of a section through a goblet cell (pink & blue) and secretory cells of the duodenum, part of the small intestine. The goblet cell secretes mucus which neutralises stomach acid. The mucigen granules (circular objects, at upper centre) combine with water to form the mucus. On either side of the goblet cell are the secretory cells whose secretions help in the digestive process. The microvilli (green hair- like structures,
Goblet cells- they make your mucous.

Mitochondria, SEM: "is a membrane-enclosed organelle found in most eukaryotic cells, ranging from 0.5 to 1.0 micrometer (μm) in diameter. Described as "cellular power plants" because they generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy. In addition to supplying cellular energy, mitochondria are involved in other tasks such as signaling, cellular differentiation, cell death, as well as the control of the cell cycle and cell growth."
