Study Notes
Cytoplasmic Structure and Composition
- The primary factor responsible for the ability of cytoplasm to change from a liquid to a semisolid state is the sol-gel transition.
- Organelles such as mitochondria, ribosomes, and lysosomes are located within the cytoplasmic matrix.
- A group of organelles known as membrane-bound organelles, including the endoplasmic reticulum, Golgi apparatus, and lysosomes, have plasma membranes separating their internal environment from the cytoplasm.
- The cytoplasmic matrix is composed of water, salts, sugars, and various organelles suspended in a gel-like substance.
- The transition of cytoplasm from a liquid to a semisolid state is brought about by the sol-gel transition, which is influenced by factors such as temperature, pH, and concentration of solutes.
