Another way to define an oblique asymptote for a rational function R(x) is, Since the perpendicular distance between R(x) and the line y = mx+b approaches zero as x becomes unbound. The function R(x) = `(x^2+1)/x`. The degree of the numerator is exactly one more than the degree of the denominator.
An archegonium (pl: archegonia), from the ancient Greek á¼ÏÏÎ® (beginning) and Î³ÏÎ½Î¿Ï (offspring), is a multicellular structure or organ of the gametophyte phase of certain plants producing and containing the ovum or female gamete.
Alternative Titles: archegonia, oogonia. Archegonium, the female reproductive organ in ferns and mosses. An archegonium also occurs in some gymnosperms, e.g., cycads and conifers. A flask-shaped structure, it consists of a neck, with one or more layers of cells, and a swollen baseâthe venterâwhich contains the egg. Neck-canal cells, located above the egg, disappear as the archegonium matures, thus producing a passage for entry of the sperm. The sperm are produced in the corresponding male reproductive organ, the antheridium. The female reproductive organ, or archegonium, emerging from a thalloid liverwort.
