A plant cell is the basic building block of a plant. Plant cells, like all eukaryotic cells, contain a nucleus and other organelles, each with its distinct functions. However, plant cells also possess unique components that differentiate them from animal, fungal, and bacterial cells. Plant Cell Characteristics Plant cells are eukaryotic. What is a Plant Cell? Plant Cell Diagram Plant Cell Structure Plant Cell Types Plant Cell Functions What is a Plant Cell? Plant cells are eukaryotic cells that vary in several fundamental factors from other eukaryotic organisms. Both plant and animal cells contain a nucleus along with similar organelles.

Plant cells are eukaryotic cells, that are found in green plants, photosynthetic eukaryotes of the kingdom Plantae which means they have a membrane-bound nucleus. They have a variety of membrane-bound cell organelles that perform various specific functions to maintain the normal functioning of the plant cell. Table of Contents turgor See all related content → plant cell, the basic unit of all plants. Plant cells, like animal cells, are eukaryotic, meaning they have a membrane-bound nucleus and organelles. The following is a brief survey of some of the major characteristics of plant cells. For a more in-depth discussion of cells, see cell. 3. DNA, the heredity information of cells, which can be found in a nucleus of eukaryotic cells and the a nucleoid region of prokaryotic cell. 4. ribosomes, or protein-synthesizing structures composed of ribosomes and proteins. These structures can be found on the image of the plant cell (Figure 3.1.2.1 3.1.2. 1 ). Figure 10.1.5 10.1. 5: A micrograph of a cell nucleus. The nucleolus (A) is a condensed region within the nucleus (B) where ribosomes are synthesized. The nucleus is surrounded by the nuclear envelope (C). Just oustide the nucleus, the rough endoplasmic reticulum (D) is composed of many layers of folded membrane.

The graphic below illustrates the key parts of the plant cell. Diagram of a plant cell. Licensed from Shutterstock. Cell wall. The outer covering of the cell, the cell wall is a rigid membrane that contains cellulose (a carbohydrate that is indigestible for humans). The cell wall protects the parts inside, and the cellulose molecules in the wall provide the support and rigidity needed to. Below is a list of the main parts shown in the plant cell diagram and the roles that they play in the cell. Nucleus - contains the genetic information of the cell. Nuclear envelope - double membrane surrounding the nucleus. Perinuclear space - space between the two membranes of the nuclear envelope. Plant Cell Diagram 1) Cell Wall It is the outermost, protective layer of a plant cell having a thickness of 20-80 nm. Cell walls are made up of carbohydrates such as cellulose, hemicellulose, and pectin and a complex organic polymer called lignin. Functions Providing mechanical strength, support, and rigidity to the cell A diagram of a plant cell with the organelles labeled The plant cell has many different features that allow it to carry out its functions. Each of these structures, called organelles, carry out a specialized role. Animal and plant cells share many common organelles, which you can find out more about by visiting the " Animal Cell " article.

Plant Cell Structure is a topic within the cell biology and is included in A-Level Biology. This page includes a diagram of a plant cell together with notes about the parts of plant cells including organelles present in plant cells, such as mitochondria, chloroplasts and Golgi apparatus. These notes include links to further information about the structures and functions of the parts of plant. Plant Cell Structure and Parts Explained With a Labeled Diagram We know plants from time immemorial and they are a part of our day-to-day life, either directly or indirectly, but do we actually know what does a plant cell structure look like? What are the different plant cell parts and their functions? Here are the answers.
A Labeled Plant Cell Amyloplasts A major component of plants that are starchy in nature, the amyloplasts are organelles that store starch. They are classified as plastids, and are also known as starch grains. They are responsible for the conversion of starch into sugar, that gives energy to the starchy plants and tubers. A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape.
