The parts of the plant cell are as follows: Plants cell constitute of membrane bound nucleus and many cellular structures. These organelles carry out funct ions that are necessary for the proper functioning and survival of the cell. The cell orga nelles of the plant are enclosed by a cell wall and cell membrane.
Plant Parts-Stems. Stems carry water and nutrients taken up by the roots to the leaves. Then the food produced by the leaves moves to other parts of the plant. The cells that do this work are called the xylem cells.They move water. The phloem cells move the food.Stems also provide support for the plant allowing the leaves to reach the sunlight that they need to produce food.lant Parts-Stems.
