Cell Cycle and Mitosis: Standard 1.2.2

Front

What is the cell cycle?

Back

The cell cycle is the series of events that take place in a cell leading to its division and duplication (replication). It consists of interphase and the mitotic phase.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (M phase, which includes mitosis and cytokinesis).

Front

What occurs during interphase?

Back

During interphase, the cell grows, duplicates its DNA, and prepares for mitosis. It consists of three sub-phases: G1 (growth), S (DNA synthesis), and G2 (preparation for mitosis).

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate daughter cells.

Front

What happens during anaphase?

Back

During anaphase, the sister chromatids are pulled apart to opposite poles of the cell.

Front

What is the role of contractile vacuoles in unicellular organisms?

Back

Contractile vacuoles help unicellular organisms remove excess water to maintain osmotic balance.

Front

How many chromosomes does a daughter cell have after mitosis if the parent cell has 50 chromosomes?

Back

The daughter cell will also have 50 chromosomes, as mitosis results in the equal distribution of chromosomes.

Front

What is the importance of buffers in cells?

Back

Buffers help maintain a cell's homeostasis by stabilizing pH levels, which is crucial for proper cellular function.

Front

What occurs after interphase in the cell cycle?

Back

After interphase, the cell undergoes mitosis, where the chromosomes are separated into two daughter cells.
