During which phase does the cell grow and make a copy of its DNA?

• Cytokinesis

• M phase

• Interphase

• G0 phase

What happens during the G1 phase of interphase?

• The cell grows and copies organelles

• The cell condenses its DNA into chromosomes

• The cell synthesizes a complete copy of DNA

• The cell divides its cytoplasm

Which structure helps separate DNA during M phase?

• Centrosome

• Nucleus

• Cell wall

• Ribosome

• To reorganize cell contents

• To condense DNA into chromosomes

How does cytokinesis differ in plant and animal cells?

• Animal cells form a cell plate, plant cells form a cleavage furrow

• Animal cells form a cleavage furrow, plant cells form a cell plate

• Both form a cell plate

• Both form a cleavage furrow

What is the G0 phase?

• A phase where the cell is actively preparing to divide

• A resting state where the cell is not preparing to divide

• A phase where the cell duplicates its DNA

• A phase where the cell divides its cytoplasm
