The puckering or crinkling of leaves due to different growth rates in adjacent tissue is known as savoying. The simple tissues (tissues with uniform cells) are composed of the same type of cells; complex tissues (tissues with more than one type of cells) are composed of more than one type of cell, these are unique to plants. So I guess that would make it an organ. We will present its structure with respect to its functions in photosynthesis, gaseous exchange and transport. An organ is a collection of tissues that have a purpose. The leaves are the primary photosynthetic organs of plants, serving as key sites where energy from light is converted into chemical energy.
