As part of this interface, the UART also: 1  Converts the bytes it receives from the computer along parallel circuits into a single serial bit stream for outbound transmission. 2  On inbound transmission, converts the serial bit stream into the bytes that the computer handles.
Cell specialization is the process in which a generic cell develops  into a specific type of cell. This happens in response to specific  triggers from the body or the cell iâ¦tself. Three examples of  specialized cells are the sperm cell, the fat cell, and the white  blood cell.
All plant cells are characterized by several common features, such as chloroplasts, a cell wall, and a large vacuole. These features also differentiate plant cells from animal cells. In addition, there is a number of specialized types of plant cells that are found only in vascular plants. These include parenchyma cells, collenchyma cells, and sclerenchyma cells. 1. Parenchyma cells. The term parenchyma is derived from the Greek word para, which means âbesideâ, and en + chein, meaning âto pour inâ. Parenchyma cells are the biochemistry machines of the plant. They are usually described as the typical plant cell, because they are not very specialized. These cells are commonly found in leaves, roots, and stems, usually having a spherical shape with only primary cell walls and highly functional cytoplasm. Source.
