Select the correct option:
$(1)$ In animal cells,cytokinesis occurs by cell plate / cell furrow.

$(1)$ In animal cells,cytokinesis occurs by cell plate / cell furrow.
$(2)$ Mitosis occurs only in somatic cells / both somatic and germ cells.
(A) $(1)$ In animal cells,cytokinesis occurs by the formation of a cell furrow (cleavage furrow) that deepens centripetally.
$(2)$ Mitosis occurs in both somatic cells (for growth and repair) and germ cells (for the proliferation of germinal epithelium) in many organisms.
