10 Questions
In animals, which type of cells exhibit mitotic cell division?
Diploid somatic cells
What is the term used to describe the inactive stage of the cell cycle where cells remain metabolically active but no longer proliferate?
Quiescent stage (G0)
Which plant species and stages demonstrate mitosis in haploid cells based on the text?
Mosses - Gametophyte stage
What is another term for the M phase of the cell cycle?
Mitotic phase
Why is mitosis referred to as equational division?
It involves nuclear division (karyokinesis)
What is the main characteristic event that marks the completion of prophase in karyokinesis?
Condensation of chromosomal material to form compact mitotic chromosomes
What distinguishes chromosomes in prophase from chromosomes in interphase?
Chromosomes in prophase are composed of two chromatids attached at the centromere, whereas interphase chromosomes are single-stranded.
What organelle radiates out microtubules called asters during prophase?
Centrosome
In which phase of the cell cycle does prophase occur?
M phase
What is the primary function of spindle fibers in mitosis?
To separate chromatids and pull them to opposite poles
Test your knowledge on the G0 phase of the cell cycle, where cells become quiescent and do not actively divide unless needed for tissue repair or growth. Understand how cells transition into this stage and their metabolic activity in G0.
