Diagram shows a stage of mitosis.
What is the stage and what feature can be seen in this stage?
Telophase : Homologous chromosomes are pulled to opposite cell poles because of the shrinking of the spindle fibres.
Prophase : Homologous chromosomes are pushed towards each other because of the bloating of the spindle fibres.
Metaphase : Sister chromatids move towards each other because of the bloating of the spindle fibres.
Anaphase : Sister chromatids are pulled to opposite cell poles because of the shrinking of the spindle fibres.
What is the purpose of mitosis in a
unicellular organism?
Growth
Tissue repairing
Asexual reproduction
To replace dead cells
Which of these is the importance of
mitosis?
Produce gametes
Variations
To replace dead cells
Produce haploid daughter cells
