Cell Cycle and Mitosis

A set of vocabulary flashcards covering key terms related to cell division and the cell cycle.

Centrioles

Cylindrical structures involved in the process of cell division.

Centrosome

An organelle that serves as the main microtubule organizing center.

Nucleus

The membrane-bound organelle that contains the cell's genetic material.

Nucleolus

A dense region within the nucleus where ribosome production occurs.

Interphase: G₁

The first phase of interphase where the cell undergoes metabolic activity and growth.

Chromosomes

Structures within the cell that are made up of DNA and proteins, containing genetic information.

Mitosis: Prophase

The stage in mitosis where chromosomes condense and the nucleolus disappears.

Metaphase plate

The imaginary line where chromosomes align before being separated.

Cleavage furrow

The indentation that begins the process of cytokinesis in animal cells.

Cytokinesis

The final process of cell division where the cytoplasm divides to form two daughter cells.

Anaphase

The stage of mitosis where sister chromatids are pulled apart toward opposite sides of the cell.

Telophase

The stage of mitosis where the nuclear envelope re-forms around the daughter chromosomes.

Spindle fibers

Microtubules that pull chromosomes apart during cell division.

Kinetochores

Protein structures on chromosomes where spindle fibers attach during mitosis.

Nuclear membrane

The double membrane surrounding the nucleus, which disintegrates during mitosis.
