Tennessee Code Title 43. Agriculture and Horticulture § 43-38-601

(a) All powers shall be exercised by or under the authority of, and the business and affairs of the cooperative shall be managed by or under the direction of the board of directors, subject to subsection (b) and any limitations set forth in the articles or bylaws agreement. A cooperative shall be board-managed, as designated in its articles. Unless otherwise provided in the articles or bylaws, each director shall have equal voting power per capita with each other director.

(b) For convenience, one (1) or more officers, members or directors may be designated in the articles as persons authorized to execute instruments transferring real property held in the name of the cooperative and may set forth any limitations on this authority. This designation, however, in the absence of a clear statement that the named person or persons are the only person or persons authorized to execute instruments transferring real property, does not imply that other members, officers or directors do not have the authority to execute such instruments under § 43-38-602. A grant of authority contained in the current articles is conclusive in favor of a person who gives value without knowledge to the contrary.
