-Archaeocytes
Cells that move about in the mesohyl, digest particles, and may specialize for other functions are the archaeocytes.
Explanation;
-Archaeocytes are very important to the functioning of a sponge. These cells are totipotent, which means that they can change into all of the other types of sponge cells.
-Archaeocytes ingest and digest food caught by the choanocyte collars and transport nutrients to the other cells of the sponge. In some sponges, archaeocytes develop into gametes.
The correct answer is D.
Cellular respiration is the process by which glucose molecules are broken down in the presence of oxygen to produce energy in form of ATP, water and carbon dioxide are also given off as the by products of the reaction. Thus, for cellular respiration to occur, the raw materials that are needed are glucose and oxygen while the products of the reaction that are formed are energy, water and carbon dioxide. Living organisms used the energy produced to carry out life sustaining activities of the cells.
