Expert Answer:

1. Functions of asters:
  • Asters hold the two centrioles at the two opposite poles.
  • The asters then provide support and guidance to the chromosomes, ensuring that chromosomes end up in the right place as mitosis occurs.
2. A centrosome is an amorphous structure containing two centrioles while a centriole is an organelle with an intricate microstructure.
 
3. Homologous chromosomes have corresponding DNA sequences and come from separate parents; one homolog comes from the mother and the other comes from the father. Homologous chromosomes line up and synapse during meiosis.
