Cell Biology and the Cell Cycle

These flashcards cover key vocabulary related to cell biology and the cell cycle, emphasizing definitions and important concepts.

Endocytosis

The movement of material into the cell using vesicles.

Exocytosis

The movement of material out of the cell using vesicles.

Cell Cycle

A repeated pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells.

Interphase

The first phase of the cell cycle, consisting of G1, S, and G2 phases, where the cell grows and prepares for division.

Mitosis

The second phase of the cell cycle where the cell's chromosomes are separated into two new nuclei.

Cytokinesis

The division of the cytoplasm into two individual cells.

Apoptosis

Programmed cell death, a process where lysosomes release enzymes that contribute to cell death.

Cancer

Uncontrolled cell division that occurs when cell cycle regulation breaks down, leading to tumor formation.

Benign Tumor

A cluster of abnormal cells that typically remain together and do not spread to other parts of the body.

Malignant Tumor

Cancer cells that break away from a tumor and spread to other body parts, leading to more tumors.
