This is the phase where the cell spends most of its time growing in size.
Metaphase
Interphase-
What phase comes before mitosis in the cell cycle?
Interphase
Telophase
Cytokinesis
Prophase
What occurs during interphase?
Cell division
Nuclear envelope breakdown
Cell growth and DNA replication
Chromosome separation
What phase comes before mitosis in the cell cycle?
Metaphase
Cytokinesis
Interphase
Prophase
What is the main purpose of mitosis?

Anaphase
Which stage involves sister chromatids being pulled apart?
Anaphase
Cytokinesis
Telophase
Prophase
What is the final stage of mitosis called?
Telophase
Metaphase
Interphase
Prophase
What occurs to the chromosomes during prophase of mitosis?
They condense
They disappear completely from view.
They divide into two identical sets.
They lengthen and become less organized.
What happens to the nuclear envelope/membrane in prophase?
It breaks down and disappears completely.
It remains unchanged during prophase.
It thickens and strengthens.
It forms new nuclei for daughter cells.
What structure forms the spindle fibers in prophase?
Centrioles begin to move to opposite poles.
Nuclear envelope forms the spindle fibers.
Chromatids group together at the center.
Centrosomes contract and shrink.
In prophase, what is the state of the chromosomes?
They are already separated into daughter cells.
They are not yet fully formed.
They are single and unpaired chromosomes.
The chromatin condenses to form “X” shaped replicated chromosomes. (Two sister chromatids held together by one centromere
What occurs during metaphase of mitosis?
Nuclear membrane dissolves completely.
Chromosomes duplicate for the next phase.
Sister chromatids separate from each other.
Chromosomes align at the cell equator.
What is the key characteristic of metaphase?
Cell has not yet divided yet.
The nucleus has disappeared from the cytoplasm and chromosomes line up in the middle of the cell
Chromosomes are clustered in one corner.
Nuclear envelope forms around chromosomes.
What happens to chromatids during anaphase?
They become invisible to the eye.
They line up in the center.
They are pulled apart to opposite poles.
They duplicate in the nucleus.
What phase comes before anaphase in the cell cycle?
Metaphase
Prophase
Interphase
Telophase
What reappears during telophase?
Nuclear envelope around each set of chromosomes forms.
Centrioles move to opposite poles of the cell.
Chromosomes are pulled apart at the centromeres.
Spindle fibers begin to break down and dissolve.
What is the main outcome of telophase?
Cells start to undergo apoptosis immediately.
Cell prepares for DNA synthesis phase to begin.
Chromosomes are fully separated into daughter cells.
Formation of two distinct nuclei before cell division completes.
What is the third step in eukaryotic cell division?
Mitosis
Replication
Cytokinesis
Interphase
What divides during the third step of cell division?
Cytoplasm
Nucleus
DNA
Cell membrane
What do two daughter cells form after completing which step?
Mitosis
Cytokinesis
Interphase
Anaphase
During which stage does the cytoplasm split into two?
Telophase
Metaphase
Prophase
Cytokinesis
At the end of the cell cycle, what is produced?
Four varied cell types.
Two different daughter cells.
One larger parent cell.
Two identical daughter cells.
Which phase occurs before cell division in the cycle?
Interphase.
Metaphase.
Prophase.
Cytokinesis.
What is the main purpose of the cell cycle?
To grow and replicate cells.
To change cell shape.
To remove waste products.
To produce energy only.
What happens during cytokinesis?
The cytoplasm divides between the two new cells.
DNA duplicates into two strands.
Cells grow larger than normal.
Nuclear membranes form again.
What does diploid mean in terms of chromosomes?
Two complete sets of chromosomes in a cell.
Half the number of chromosomes in a cell.
One complete set of chromosomes in a cell.
Three complete sets of chromosomes in a cell.
In humans, what is the diploid number?
22 chromosomes in a somatic cell.
23 chromosomes in a somatic cell.
46 chromosomes in a gamete.
46 chromosomes total in a somatic cell.
Which cells in humans are diploid?
Gametes, such as sperm and egg cells.
Nerve cells only.
Red blood cells only.
Somatic cells, like skin and muscle cells.
What process produces diploid cells in organisms?
Fertilization, which combines genetic material.
Binary fission in prokaryotes.
Meiosis, which creates haploid cells.
Mitosis, cell division that creates identical cells.
What is binary fission?
Growth of cells in size.
A method of sexual reproduction.
A type of asexual reproduction in single-celled organisms.
Cell division in multicellular organisms.
Which organism primarily uses binary fission?
All types of animals.
Bacteria and some single-celled organisms.

What is a key step in binary fission?
Fusion of two cells together.
Replication of DNA before division occurs.
Formation of gametes.
