a group of cells that specialize to perform a function is known as a tissue e.g., Xylem is a water conducting tissue of higher plants comprising mainly of parechyma, companian cell and vessels.
That would be an organ.
tissue? tissue?
Organs can perform the most complicated jobs because an organ is composed of organized tissues and cells.
Brain cells and lung cells are different because they each have different functions and carry out different jobs and specialize in different things.
Tissues
all cells preform various jobs or functions. theres not one cell that does nothing. if a cell does nothing than its most likely not a cell.
an organ.

tissue? tissue?
every one except stem cells.
A group of similar cells that perform a certain task is called as a tissue.
An organ.
Plant cells do specialize but not in the same way as animal cells. Animal cells have specialized cells such as nerve cells, reproductive cells or muscle cells etc. Plant cells do not have any of those. But Plant cells have other specialized cells such as photosynthesis cells, epidermal cells etc. Both Animal and Plant cells have specialized cells that perform a specific function to keep the cell/organism alive.
If the cells did not specialize than there would be no chick developing.
all cells perform mitosis, except sex cells which perform meiosis
Somatic cells are all the cells in an organism's body except for the gametes. Certain somatic cells may have different functions in an organism due to differences in gene expression; which simply mean that somatic cells only use certain parts of the DNA. Therefore, all somatic cells have the same DNA. When these cells develop, they will specialize into certain types of cells depending on which genes will turn "on."
Because cells produce a lot of protein to build new cells, and to perform certain functions, and to repair damaged tissues.
stem cells They are unspecialised and can become specialised to perform certain function
