Question

1) Examine the picture of an onion root tip with cells in various stages of the cell cycle. A student claims that interphase is the longest stage of the cell cycle. Another student claims that mitosis is the longest stage. Using evidence from the photo, determine which student is correct and why.

A) Mitosis is the longest stage because anaphase requires more time to separate chromatids.

B) Interphase is the longest stage because chromosomes are visible in the majority of the cells.

C) Mitosis is the longest stage because the majority of the cells in the photo are replicating their DNA.

D) Interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing.

This image displays a microscopic view of plant cells undergoing various stages of mitosis, stained to highlight the chromosomes. The purple staining makes the chromosomes clearly visible against the lighter background of the cell cytoplasm.

### Explanation of the Image:

1. **Cells and Staining:**
- The cells are outlined and appear hexagonal due to the plant cell walls.
- The darker purple areas indicate the chromosomal material, which is stained for visibility.

2. **Stages of Mitosis:**
- **Interphase:** Seen as cells with a dense, dark center, indicating the nucleus where the chromatin is not yet condensed.
- **Prophase:** Chromosomes begin to condense and become visible as distinct structures.
- **Metaphase:** Chromosomes align in the middle of the cell, forming a distinct line across the equator.
- **Anaphase:** Chromosomes are pulled apart to opposite poles of the cell, visible as distinct strands extending from each pole.
- **Telophase:** Chromosomes are at the poles, and the cell begins to divide, with a visible indentation indicating the process of cytokinesis.

3. **Scale Bar:**
- Located in the lower left corner, indicating a length of 10 micrometers (μm), providing a reference for the size of the cells and structures observed.

This image is a useful educational tool for understanding the cellular process of mitosis, highlighting the dynamic transformation of chromosomes during cell division in plants.
