Vacuoles: Often the largest organelle in a plant cell, bounded by a single membrane called tonoplast. Function: Vacuoles play a major role in autophagy, maintaining a balance between biogenesis (production) and degradation of many substances and cell structures. A plant cell is a fundamental unit of a Plant's structure. A plant cell is a eukaryotic cell, i.e., it has a defined nucleus enclosed within a membrane. Plant cells and animal cells difference occurs as they possess unique features that allow them to carry out essential functions. Plant cell structure consists of a freely permeable cell wall. In this article, we will discuss plant cell parts and functions, its diagram and more in detail. Plant Cell Diagram The plant cell is rectangular and comparatively larger than the animal cell. Even though plant and animal cells are eukaryotic and share a few cell organelles, plant cells are quite distinct when compared to animal cells as they perform different functions. Some of these differences can be clearly understood when the cells are examined under an electron microscope. The onion cell which is a typical plant cell, has a distinct cell wall as its outer boundary and just within it is the cell membrane. The cells of the human cheek have an outer membrane as the delimiting structure of the cell.
