What Is a Malpighian Tubule? Malpighian tubules are organs within insects that excrete solid waste. Larvae of certain species of beetles use Malpighian tubules to produce silk.
Microtubules (micro- + tube + -ule) are a component of the cytoskeleton, found throughout the cytoplasm. These tubular polymers of tubulin can grow as long as 50 micrometres and are highly dynamic.The outer diameter of a microtubule is about 24 nm while the inner diameter is about 12 nm.They are found in eukaryotic cells and are formed by the polymerization of a dimer of two globular proteins, alpha and beta tubulin.icrotubules (micro- + tube + -ule) are a component of the cytoskeleton, found throughout the cytoplasm.
