Answer:
- each of a pair of minute cylindrical organelles near the nucleus in animal cells, involved in the development of spindle fibres in cell division.
- Microtubules are polymers of tubulin that form part of the cytoskeleton and provide structure and shape to eukaryotic cells. ... They are formed by the polymerization of a dimer of two globular proteins, alpha and beta tubulin into protofilaments that can then associate laterally to form a hollow tube, the microtubule.
- A ribosome is a complex of RNA and protein and is, therefore, known as a ribonucleoprotein. ... The two subunits are joined to each other by interactions between the rRNAs in one subunit and proteins in the other subunit. Ribosomes are located inside the cytosol found in the plant cell and animal cell.

Answer:
Explanation:
1-centriole:-Centrioles are paired barrel-shaped organelles located in the cytoplasm of animal cells near the nuclear envelope.
2-micotubules:-Microtubules extend throughout the cell providing it with proper shape and keeping the organelles in place. They are the largest structures in the cytoskeleton and are about 24 nm thick. They facilitate cell movement, cell division, and transportation of materials within the cells. They are also involved in the division of chromosomes during the process of mitosis and in locomotion.
3-ribosome:-A ribosome is a complex molecular machine found inside the living cells that produce proteins from amino acids during the process called protein synthesis or translation. The process of protein synthesis is a primary function, which is performed by all living cells.
