Question

what occurs during interphase?
the cell is split into 2
the chromatids separate
the nuclear envelop (membrane) disappears
the cell grows

which organelle is needed for cell division?
chloroplasts
cytomere
centrioles
cilia

which of the following represents the phases of mitosis in their proper sequence?
interphase, prophase, metaphase, telophase
prophase, metaphase, anaphase, telophase
prophase, metaphase, anaphase, cytokinesis
interphase, prophase, metaphase, anaphase, telophase

Explanation:

• First question:
• During interphase, the cell grows, replicates its DNA, and prepares for cell division. The cell is split into 2 during cytokinesis. Chromatids separate during anaphase. The nuclear envelope disappears during prophase.
• Second question:
• Centrioles are involved in organizing the spindle fibers during cell division. Chloroplasts are for photosynthesis. "Cytomere" is not a standard organelle related to cell division. Cilia are for movement (like in some cells to move substances).
• Third question:
• The phases of mitosis (excluding interphase which is a preparatory stage but not part of mitosis itself) in order are prophase (chromosomes condense, nuclear envelope breaks down), metaphase (chromosomes line up at the equator), anaphase (sister chromatids separate), telophase (nuclear envelopes reform). Cytokinesis is the division of the cytoplasm which is separate from the four - stage mitosis process.

Answer:

• First question: the cell grows
• Second question: centrioles
• Third question: prophase, metaphase, anaphase, telophase
