What are Organelles?

Organelles are micro-organs with specific morphological structures and functions in the cytoplasm, also called pseudo-organs or substructures. Among them, plastids and vacuoles can be distinguished under a light microscope, and other organelles generally need to be observed with the help of an electron microscope. ^[1]

The organelles are divided into:

Golgi apparatus (Golgi apparatus, Golgi complex) is also called Golgi complex, Golgi apparatus. Yes

The lysosome has a single-layer membrane structure and is a "digestion workshop".

Mitochondria are rod-shaped

The chloroplast has a bilayer membrane. Is the organelles contained in the cells of green plants that can carry out photosynthesis, producing oxygen and organic matter,

American cell biologist K. R. Porter observed the cells cultured in vitro with glutaraldehyde fixation with a high-penetration high-pressure electron microscope, and only found a microbeam network in the cell matrix. So the matrix is divided into two parts: microbeam network, distributed throughout the cell, is composed of protein-based microbeam fibers. Water-like cyberspace, in which a variety of small molecules such as sugar, amino acids, and inorganic salts are dissolved or suspended. The edges of the microbeam network are attached to the plasma membrane of the cell, and are interwoven with cytoskeleton components such as microtubules and microfilaments to form a network frame, supporting organelles such as endoplasmic reticulum and mitochondria. Free polysomes are suspended at the intersections of the trabecular network. The entire cytoplasm presents a complex structural order.

Some people first treated the cells with detergents to remove soluble proteins, and then used a modified water-drying method to prepare cell specimens. Microbeam structures were not visible under an electron microscope. Without a detergent treatment, a microbeam network appears. Therefore, it is uncertain whether the microbeam network really exists.
