Cell Division and Mitosis

What is the process of cell division called?

• Cytokinesis

• Interphase

• Mitosis

• Telophase

What happens during mitosis?

• Cells grow and perform normal functions

• Chromosomes duplicate and separate

• Cell membrane divides

• Cell plate forms in plant cells

Which stage of the cell cycle is longer?

• Interphase

• Mitosis

• Prophase

• Anaphase

What is the function of centrosomes in mitosis?

• Transport materials in and out of the cell

• Produce fibers that form a spindle

• Duplicate and separate chromosomes

• Pinch the cell membrane during cytokinesis

What happens during prophase?

• Chromosomes line up along the center of the cell

• Centrosomes move to opposite poles of the cell

• Cell membrane pinches in at both ends of the cell

• Nuclear membrane starts to form around each set of chromosomes

Which type of cells have centrioles in their centrosomes?

• Animal cells

• Plant cells

• Fungal cells

• Algal cells

What happens during metaphase?

• Chromosomes start to condense and become thicker

• Spindle fibers pull the sister chromatids towards opposite poles of the cell

• Centromere of each chromosome divides, separating the sister chromatids

• Nuclear membrane and nucleolus disappear

What is the purpose of anaphase in mitosis?

• To ensure each daughter cell gets a complete set of chromosomes

• To duplicate and separate chromosomes

• To form a cell plate in plant cells

• To relax and disperse the chromosomes in the cell nucleus

How does cytokinesis occur in animal, fungal, and algal cells?

• Cell membrane pinches in at both ends of the cell

• Cell plate forms at the middle of the cell and grows outward

• Spindle fibers attach to the chromosomes' centromeres

• Chromosomes start to condense and become thicker

What happens to the chromosomes after mitosis and cytokinesis?

• They duplicate and separate

• They relax and become threadlike and dispersed in the cell nucleus

• They form a cell wall in plant cells

• They transport materials in and out of the cell
