Plant Cell Structure
cell wall
It is a rigid layer which is composed of cellulose, glycoproteins, lignin, pectin and hemicellulose. It is located outside the cell membrane. It comprises proteins, polysaccharides and cellulose.The primary function of the cell wall is to protect and provide structural support to the cell
cell membrane
It is the semi-permeable membrane that is present within the cell wall. It is composed of a thin layer of protein and fat.The cell membrane plays an important role in regulating the entry and exit of specific substances within the cell.
nucleous
The nucleus is a membrane-bound structure that is present only in eukaryotic cells. The vital function of a nucleus is to store DNA or hereditary information required for cell division, metabolism and growth.
plastids
They are membrane-bound organelles that have their own DNA. They are necessary to store starch, to carry out the process of photosynthesis. It is also used in the synthesis of many molecules, which form the building blocks of the cell.
central vacoule
It occupies around 30% of the cell’s volume in a mature plant cell. Tonoplast is a membrane that surrounds central vacuole. The vital function of central vacuole apart from storage is to sustain turgid pressure against the cell wall. The central vacuole consists of cell sap. It is a mixture of salts, enzymes and other substances.
golgi apparatus
They are found in all eukaryotic cells which are involved in distributing synthesized macromolecules to various parts of the cell.
ribosomes
They are the smallest membrane-bound organelles which comprise RNA and protein. They are the sites for protein synthesis, hence, also referred to as the protein factories of the cell.
mitochondria
They are the double-membraned organelles found in the cytoplasm of all eukaryotic cells. They provide energy by breaking down carbohydrate and sugar molecules, hence they are also referred to as the “Powerhouse of the cell.”
lysosomes
Lysosomes are called suicidal bags as they hold digestive enzymes in an enclosed membrane. They perform the function of cellular waste disposal by digesting worn-out organelles, food particles and foreign bodies in the cell.
