Cytoplasm

The cytoplasm is a jelly-like substance that fills the inside of a cell. It is a semi-fluid matrix that contains various organelles, such as the endoplasmic reticulum, Golgi apparatus, mitochondria, and ribosomes.

Composition

The cytoplasm is composed of water, salts, and organic molecules, including proteins, lipids, carbohydrates, and nucleic acids.

Functions

• Support and Shape: The cytoplasm helps maintain the shape of the cell and provides support for organelles.
• Cellular Metabolism: It is involved in various metabolic processes, including protein synthesis, energy production, and the synthesis of lipids and carbohydrates.
• Transport: It serves as a medium for the transport of materials within the cell.
• Storage: The cytoplasm stores nutrients, ions, and waste products.
