The Cell Cycle

Front

What is the M phase in the cell cycle?

Back

The M phase is the stage of the cell cycle where cell division occurs, including both mitosis and cytokinesis.

Front

Which types of organisms perform cellular respiration?

Back

Both Autotrophs and Heterotrophs perform cellular respiration.

Front

What is a checkpoint in the cell cycle?

Back

A checkpoint is a stage in the eukaryotic cell cycle where the cell assesses internal and external signals to decide whether to proceed with division.

Front

What is NOT true about the cell membrane?

Back

The cell membrane does not contain digestive enzymes.

Front

What is exocytosis?

Back

Exocytosis is a type of active transport that releases particles from a cell when the vesicle membrane fuses with the cell membrane.

Front

What is the purpose of the G1 phase in the cell cycle?

Back

The G1 phase is the first stage of interphase where the cell grows and prepares for DNA replication.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in the duplication of chromosomes.

Front

What happens in the G2 phase of the cell cycle?

Back

In the G2 phase, the cell continues to grow and prepares for mitosis, checking for DNA damage and ensuring all DNA is replicated.

Front

What is the role of the cell membrane?

Back

The cell membrane controls what enters and leaves the cell and provides protection and structure.

Front

Define mitosis.

Back

Mitosis is the process of nuclear division in eukaryotic cells that results in two identical daughter cells.
