(a) Microsomes are the fragments of endoplasmic reticulum and attached ribosomes that are obtained by the centrifugation of homogenized cells.

(b) Microtubules are the microscopic tubular structures present in the cytoplasm of cells, and they sometimes aggregate to form more complex structures.

(c) Cilia and flagella are the locomotory structures found in cells that are made up of microtubules.

(d) Lysosomes are membrane-bound organelles that are found in eukaryotic cells. These are cell organelles rich in acid phosphatase and other hydrolytic enzymes.
