Draw a well-labelled diagram of plant cell and mention the function of any three parts of it.
Answers
The diagram of plant cell is as follows:
Plant cells are eukaryotic cells that change in several fundamental factors from other eukaryotic organisms. Both plant and animal cells contain nucleus alongside similar organelles. One among the distinctive aspects of a plant cell is the presence of a cell wall outside the cell membrane.
Plant cell structure includes various components referred to as cell organelles that perform different functions to sustain itself. These organelles include,
Cell Wall: It's a rigid layer which consists of cellulose, glycoproteins, lignin, pectin and hemicellulose. It’s located outside the cell wall. It comprises proteins, polysaccharides and cellulose.
Cell membrane: It's the semi-permeable membrane that's present within the cell wall. It’s composed of a skinny layer of protein and fat. The cell wall plays a crucial role in regulating the entry and exit of specific substances within the cell.
Nucleus: 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 cellular division, metabolism and growth.
Central Vacuole: It occupies around 30 percent of the cell’s volume during a mature plant cell. The vital function of central vacuole aside from storage is to sustain turgor pressure against the cell membrane. The central vacuole consists of cell sap. It’s a mix of salts, enzymes and other substances.
Golgi apparatus: they're found altogether in eukaryotic cells which are involved in distributing synthesized macromolecules to varied parts of the cell.
Ribosomes: they're the littlest membrane-bound organelles which comprise RNA and protein. They’re the sites for protein synthesis, hence, also mentioned because of the protein factories of the cell.
Mitochondria: they're the double-membrane organelles found within the cytoplasm of all eukaryotic cells. They supply energy by breaking down carbohydrate and sugar molecules, hence they're also mentioned because of the “Powerhouse of the cell.”
Lysosome: Lysosomes are called suicidal bags as they hold digestive enzymes in an indoor membrane. They perform the function of cellular waste disposal by digesting worn-out organelles, food particles and foreign bodies within the cell.
