By definition, a tissue is an aggregate of similar cells that perform a specific function. A tissue is also characterised by the presence of extracellular matrix, which is secreted by the cells and provides support and structure to the tissue.
A cluster of eggs, on the other hand, is not a collection of similar cells. It contains various types of cells, including ova (immature egg cells), nurse cells, and follicular cells. These cells do not perform a specific function as a group, and they are not held together by an extracellular matrix.
Therefore, a cluster of eggs does not meet the criteria for a tissue and cannot be considered one.
