Homework Answers
The cell begins to elongate during this phase: Prophase( Accurately interphase. But it is not given in option Among the options you have given prophase is nearly correct.)
Explanation:
During prophase the cell grows in size and elongates.
The nuclear envelope is fully reformed during this phase: Telophase
Explanation:
During telophase the nuclear envelope which is dissolved reformed.The choromosomes are at pole during this phase and are becoming more diffuse.
During this phase the mitotic spindle from each pole attaches to one sister chromatid : Prometaphase.
Explanation: During prophase the centrosomes devide. During early metaphase ( Prometaphase) mitotic spindle appears from the centrosomes and each pole attaches to one sister chromatid.
The mitotic spindle begins to break down during this stage: Anaphase.
Explanation:
During anaphase the sister chromatids are separated due to pulling of spindle fibres in opposite direction. In this process the spindle fibre also gets broken due to pulling.
The chromosomes begin to condense during this phase: Prophase
Explanation: During prophase the chromosomes get condensed and the nuclear envelope disappears.
The mitotic spindle lines the sister chromatids up end to end on the middle plane during this phase: Metaphase.
Explanation:
During metaphase the thick coiler chromosomes each containing two chromatids allign in the metaphasic plate at the center of the cell.
The cleavage furrow forma during this stage: Cytokinesis
Explanation:
During the process of cytokinesis central furrow appears in the cell. This helps in the division of the cell.

Match the stage of mitosis with the correct description.
Match the stage of mitosis with the correct description.a. Microtubles that are attached to each chromosome shorten, pulling the sister chromatids apart.b. The chromosomes line up single file in the middle of the cell. Sister chromatids are clearly visible in this stage.c. The chromosomes that were pulled apart reach their respective poles. The chromosomes decondense. The nuclear envelope re-forms. The cytoplasm with organelles divides.d. Chromosomes have replicated and appear as an "X". The nuclear envelope begins to break down. The...
