Which structure aids in cell division?
centrioles
nucleus
golgi apparatus
smooth ER
mitochondria
lysosome



Answer :

The structure that aids in cell division is the centrioles. Centrioles are organelles found in animal cells that play a crucial role in cell division. They are involved in organizing the microtubules that form the spindle apparatus during cell division. The spindle apparatus is responsible for separating the chromosomes during mitosis and meiosis, ensuring that each daughter cell receives the correct number of chromosomes.

In contrast, the nucleus is the control center of the cell that contains the genetic material, but it does not directly aid in cell division. The Golgi apparatus is involved in packaging and processing proteins for secretion, while the smooth ER is responsible for lipid synthesis and detoxification. Mitochondria are known as the powerhouse of the cell, producing energy through cellular respiration. Lysosomes are involved in the breakdown of cellular waste.

Therefore, among the structures listed, centrioles specifically aid in cell division by organizing the spindle apparatus, which is essential for the accurate separation of chromosomes during cell division.
