Question

cells are asexual right

Answer 1

right

Answer 2

since the terms "sexual" and "asexual" aren't valid characteristics for cells, your question can't be answered that easily.

if you look for them, you will find that some cells actually have some kind of sex assignment. the sperm cell, for example, will clearly be thought of as a male cell. there are unicellular organisms that do sexual reproduction (in the malaria cycle, for example). here, the definition of "male" and "female" is chosen by the size of the cell: the smaller one will be the male cell, usually.

a cell can't reproduce sexually by itself, since you need two participants for meiosis. if you look for that answer, then by your terms of definition, cells are asexual, i suppose. but that definition has no use outside of itself. :-)
