Centrioles
C
Mitochondria
D
Ribosomes
Verified step by step guidance1
Understand the context of the question: During cell division, the spindle apparatus is responsible for separating chromosomes into daughter cells. The structures that anchor the spindle are crucial for this process.
Recall the role of centrioles: Centrioles are cylindrical organelles found in animal cells that play a key role in organizing microtubules and forming the spindle fibers during mitosis and meiosis.
Eliminate incorrect options: Nucleoli are involved in ribosome production, mitochondria are responsible for energy production, and ribosomes are involved in protein synthesis. None of these structures are directly involved in anchoring the spindle.
Identify the correct answer: Centrioles are the structures that anchor the spindle by forming the centrosome, which serves as the microtubule-organizing center during cell division.
Conclude: The correct pair of structures that anchor the spindle during cell division are the centrioles.
