11.2 The Process of Cell Division

Front

What are the main stages of the cell cycle?

Back

The main stages of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (Prophase, Metaphase, Anaphase, Telophase).

Front

How does cytokinesis differ in plant and animal cells?

Back

In plant cells, cytokinesis involves the formation of a cell plate, while in animal cells, it involves the formation of a cleavage furrow.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs.

Front

How many chromosomes are present in each somatic cell of a human?

Back

Humans have 46 chromosomes in each somatic cell.

Front

What is the role of chromosomes in cell division?

Back

Chromosomes contain the genetic material that is replicated and distributed to daughter cells during cell division.

Front

What is Interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, consisting of G1, S, and G2 phases.

Front

What happens during Prophase?

Back

During Prophase, chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

What is the significance of the Mitotic phase?

Back

The Mitotic phase is crucial for the actual division of the cell, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What is the function of centrioles during cell division?

Back

Centrioles help in organizing the mitotic spindle, which is essential for chromosome separation.
