What are Cytoplasm and Cytoskeleton?
Cytoplasm is the jelly-like substance that fills the cell, excluding the nucleus. It is composed of water, proteins, carbohydrates, lipids, and ions. The cytoplasm contains various organelles, including mitochondria, ribosomes, endoplasmic reticulum, and Golgi apparatus.
The cytoskeleton is a network of protein filaments that provides structural support to the cell. It is composed of three types of filaments: microtubules, microfilaments, and intermediate filaments. Microtubules are long, hollow tubes that provide structural support to the cell and are involved in cell division. Microfilaments are thin, solid filaments that provide flexibility and shape to the cell. Intermediate filaments are thicker than microfilaments and less flexible. They are involved in maintaining cell shape and anchoring organelles.
The cytoplasm and cytoskeleton are essential for cell function. The cytoplasm provides a medium for metabolic reactions and houses organelles. The cytoskeleton provides structural support to the cell and is involved in cell movement and division.
