The Cell Cycle and Mitosis - Section 5.1 - Workbook Questions

Sep 28, 2026

Uploaded by Margaret

Workbook questions and study activities for Section 5.1, focusing on the cell cycle and mitosis. Includes prompts to predict how cells replace themselves, instructions to mark and highlight text, and tasks to create charts of cell life stages. Reading checks ask students to identify three cell-cycle stages, define the cell cycle, and explain what cancer results from. Materials also review the four phases of mitosis, vocabulary-based fill-in exercises, and matching and multiple-choice questions on replication, spindle fibres, and longest stages.

The three stages of the life of a cell together are called the cell cycle. These three stages are: ◆ interphase: This stage makes up most of the life of the cell. During interphase, cells grow and carry out their life functions. In cells that will divide, the nucleus makes a copy of its DNA in a process called replication. ◆ mitosis: During this stage, the nucleus of the cell divides into two equal and identical parts. Each part has a copy of the DNA. ◆ cytokinesis: During this stage, the two equal, identical parts of the cell separate. The result of this stage is two identical cells, each with a nucleus and DNA. 68 MHR • Section 5.1 The Cell Cycle and Mitosis © 2007 McGraw-Hill Ryerson Limited | Name Date | | | | --- | --- | --- | | | | | continued What are the phases of mitosis? There are four phases of mitosis. These phases are prophase, metaphase, anaphase, and telophase. | Phases of mitosis | What happens | | --- | --- | | prophase
| • the duplicated chromosomes form into an X shape and the nucleolus disappears.
• spindle fibres, which are tiny tube-like structures made of protein, begin to form in plant and animal cells | | metaphase
| • the duplicated chromosomes line up across the middle of the cell | | anaphase
| • the duplicated chromosomes move apart to opposite ends of the cell | | telophase
| • a nucleolus forms around the chromosomes atthe opposite ends of the dividing cell | How can mutagens affect the cell cycle? Mutagens can cause changes in the cell cycle so that cells keep dividing continuously. The cells pile up on top of one another, forming a lump called a tumour. The uncontrolled cell division sometimes results in diseases called cancers. Cancerous cells may grow in one place in the body, or they may spread to other parts of the body where they will continue to divide. Reading Check 2.

FAQs

What are the three stages in the life of a cell?

The three stages are interphase, mitosis, and cytokinesis. Together they make up the cell cycle.

What happens during mitosis?

During mitosis, the nucleus divides into two equal, identical parts, and each part gets a copy of the DNA.

What is cancer the result of?

Cancer can result when mutagens cause continuous uncontrolled cell division, leading to diseases called cancers.
