Question

1. this drawing shows various stages of mitosis in a fast - growing onion root tip. identify the cells (by number) which are in the following stages of mitosis: interphase prophase metaphase anaphase telophase 8. using colored pens or pencils, show how 2 chromosomes are passed from parent cell to two daughter cells.

Explanation:

Step1: Recall mitosis stage features

Interphase: Cell grows and DNA replicates, nucleus is visible and intact. Prophase: Chromosomes condense, nuclear - envelope starts to break down. Metaphase: Chromosomes line up at the cell's equator. Anaphase: Sister chromatids separate and move to opposite poles. Telophase: Nuclear envelopes reform around the separated chromosomes.

Step2: Analyze the onion - root tip cells

Without seeing the specific cell numbers clearly in the image, assume we can identify based on features. For example, cells with a clearly defined and non - condensing nucleus are in interphase. Cells with visible, condensed chromosomes and a disappearing nuclear envelope are in prophase. Cells with chromosomes aligned in the middle are in metaphase. Cells with separated chromatids moving apart are in anaphase. Cells with two distinct nuclear regions forming are in telophase.

Answer:

Interphase: [List cell numbers with intact nucleus and no visible chromosome condensation]
Prophase: [List cell numbers with condensed chromosomes and breaking nuclear envelope]
Metaphase: [List cell numbers with chromosomes aligned at equator]
Anaphase: [List cell numbers with separated chromatids moving to poles]
Telophase: [List cell numbers with reforming nuclear envelopes]

For question 8, use one color to represent one chromosome in the parent cell. During prophase, show the condensation of these two colored chromosomes. In metaphase, show them lined up at the equator. In anaphase, split each colored chromosome into two sister chromatids (still the same color) and move them to opposite poles. In telophase, show the two daughter cells, each with one copy of each colored chromosome, maintaining the same color - coding throughout to represent the passing of the two chromosomes from the parent cell to the two daughter cells.
