A tissue graft is defined as a piece of tissue that is surgically removed from one individual (the donor) and implanted into another individual (the recipient) for the purpose of repairing or replacing damaged or diseased tissues. This definition highlights the key component of a tissue graft: the transfer of biological tissue from one body to another, which can involve various types of tissue such as skin, bone, or organs.

The other options describe different concepts that are not synonymous with a tissue graft. Synthetic materials used for repairs fall under artificial grafts or biomaterials, but are not classified as tissue grafts since they do not involve biological tissues. Similarly, a piece of skin taken for cosmetic procedures refers to skin removal for aesthetic reasons and does not imply the transfer or implantation into another individual. Lastly, a method of tissue preservation is related to the techniques used to maintain the viability of tissues for future use but does not encompass the process of actual grafting. Understanding these distinctions is crucial in the context of tissue banking and transplantation, where the integrity and origin of grafts play significant roles in treatment outcomes.
