What is the main difference between membranous organelles and non-membranous organelles.
rganelles with a definite boundary created by a membrane are called membranous organelles: Nucleus, Golgi Apparatus, mitochondria, Lysosomes, ER, vacuoles, vesicles, and plastids are the main ones.
Non-membranous organelles are: ribosomes, parts of the cytoskeleton (microtubules etc), are the main ones
Non-membranous organelles are: ribosomes, parts of the cytoskeleton (microtubules etc), are the main ones
difficult word meaning
Mitochondria
Lysosomes
nucleus
- a small spherical or rodlike body, bounded by a double membrane, in thecytoplasm of most cells: contains enzymes responsible for energy production
- network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface(smooth endoplasmic reticulum) or studded with ribosomes (rough endoplasmic reticulum) involvedin the transport of materials.
- an organelle, consisting of layers of flattened sacs, that takes up and processes secretory and syntheticproducts from the endoplasmic reticulum and then either releases the finished products into various partsof the cell cytoplasm or secretes them to the outside of the cell.
Lysosomes
- a cell organelle containing enzymes that digest particles and that disintegrate the cell after its death.
nucleus
- Anatomy . a mass of nerve cells in the brain or spinal cord in which nerve fibers form connections.
