Step 1
Identify the Stages of Mitosis
Answer
To determine the order of cells in a single mitotic phase, we first need to identify the stages of mitosis depicted in the images. The key stages to recognize are prophase, metaphase, anaphase, and telophase. Each stage is characterized by specific features such as chromatin condensation, alignment at the metaphase plate, and separation of sister chromatids.
Step 2
Analyze Each Image
Answer
We must examine each image (G, H, J, L, M, P, Q) to ascertain which cell corresponds to the respective phase of mitosis. For instance:
- Image Q may depict cells in metaphase, showing aligned chromosomes.
- Image P often represents prophase, where the chromatin is condensed but not yet aligned. By maintaining this analysis for all images, we can deduce their sequential phases.
