Chloroplasts: <span>work to convert light energy of the Sun into sugars that can be used by cells. (photosynthesis)
Vacuoles: Main function is just a space-filler but can also fill digestive functions and their interiors can be used as storage for nutrients.</span>
Structure C, D, and E in the diagram represent the endoplasmic reticulum, the ribosome, and the Golgi apparatus respectively.
When the ribosomes are attached to the endoplasmic reticulum, they give it a rough appearance.
The ribosome, endoplasmic reticulum, and the Golgi apparatus work together in the synthesis and transport of protein within the cell. In other words, they are all involved in the secretory pathway of cells.
- The ribosome represents the actual site of protein synthesis.
- The endoplasmic reticulum gets involved by folding the synthesized proteins and packaging them into secretory vesicles. Thereafter, the vesicles are transported to the Golgi apparatus.
- The packaged proteins undergo further processing within the Golgi apparatus before they are exported to the cell membrane via the cytosol.
In other words, the 3 organelles work together to form the secretory pathway of the cell. They are involved in the synthesis, packaging, processing, and eventual transport of proteins to their target sites.

Answer:
Bio carbonate ions
Explanation:
The pancreas secrets an aqueous mixture ( water, digestive enzymes and bicarbonate ions) during digestion of food substances from the stomach into the duodenum to begin the process of absorption and assimilation.
The pancreatic duct are lined with duct cells. These are cells which secretes HCO3- ,into the aqueous mixture. This ion is basic. Therefore it neutralizes the acidity of the of the chyme to released from the stomach to enable the pancreatic enzyme to work.
The bicarbonate ions also prevent the walls of the pancreases from getting burnt by the effect if the acidity of the chyme.
It uses unicellular cells.
