During telophase, a line down the middle of the cell, known as the cleavage furrow in animal cells or the cell plate in plant cells, forms as the cell prepares to divide. This structure indicates the location where the cell membrane will constrict or where the new cell wall will develop, ultimately leading to cytokinesis. The cleavage furrow results from the contraction of actin filaments, while the cell plate forms from vesicles containing cell wall materials. This ensures that each daughter cell receives the necessary components for independent functioning.
What else can I help you with?
Does cytokinesis occur immediately after prophase?
No, cytokinesis occurs after telophase in the cell cycle. During prophase, the genetic material condenses into chromosomes and the nuclear envelope breaks down as the cell prepares for division. Once the chromosomes have separated during anaphase and telophase, cytokinesis follows to physically divide the cell into two daughter cells.
How can YOU tell whether cells in mitosis are animal or plant cells?
During telophase of mitosis, a cell plate is formed as the plant cell begins its division. In animal cells, the cell pinches in the center to form two cells; no cell plate is laid down.
What are four parts of mitosis?
The four parts of mitosis are prophase, metaphase, anaphase, and telophase. During prophase, chromosomes condense and the nuclear envelope breaks down. In metaphase, chromosomes line up at the cell's equator. Anaphase involves separation of sister chromatids to opposite poles, and during telophase, the nuclear membrane reforms and chromosomes decondense.
Does the nuclear envelope re-forms during anaphase?
No, the nuclear envelope does not reform during anaphase. Instead, the nuclear envelope breaks down during prophase and prometaphase to allow the chromosomes to be free in the cytoplasm for segregation and reforms during telophase.
What are the stages of meotosis?
Mitosis consists of four stages: prophase, metaphase, anaphase, and telophase. During prophase, the nuclear envelope breaks down, and chromosomes condense. In metaphase, chromosomes align at the center of the cell. Anaphase is characterized by the separation of sister chromatids, which are pulled to opposite poles. Finally, during telophase, the nuclear envelope reforms, and the chromosomes decondense.
What are the different phases of mitosis?
The different phases of mitosis are prophase, metaphase, anaphase, and telophase. During prophase, the chromosomes condense and the nuclear envelope breaks down. In metaphase, the chromosomes line up in the middle of the cell. Anaphase is when the chromosomes are pulled apart towards opposite ends of the cell. Telophase is the phase where two new nuclei form, and the cell begins to divide.
What structure disappears during telophase?
The structure that disappears during telophase is the mitotic spindle, which is responsible for separating the sister chromatids during cell division. As the cell prepares to complete division, the mitotic spindle breaks down and is no longer needed.
Does cytokinesis occur immediately after prophase?
No, cytokinesis occurs after telophase in the cell cycle. During prophase, the genetic material condenses into chromosomes and the nuclear envelope breaks down as the cell prepares for division. Once the chromosomes have separated during anaphase and telophase, cytokinesis follows to physically divide the cell into two daughter cells.
In what phase does the movement of individual chromosomes towards opposite poles occur?
In the context of cell division, chromosomes will aline in the middle of the cell during metaphase, then during anaphase they are pulled apart into two daughter cells by centrioles. I wouldn't say they are ever on opposite poles, also considering that there is no directionality of a cell.
How many nuclear membranes must form when a single dividing cell reaches telophase?
If a cell divides into two cells, duruing telophase, then there must be one nuclear membrane per cell. Therefore the answer to your question should be 2.
Summarize what happens to chromosomes during the stage of the cell cycle in which the nucleus divides Include the terms prophase metaphase anaphase and telophase?
Prophase: Chromosomes condense into visual forms and nuclear envelope breaks down. Metaphase: Chromosomes pair and line up along metaphase plate(midline) and also attatch to mitotic spindles at centromere. Anaphase: Mitotic spindles attached to chromosomes pull half of the chromosomes to each side of cell. Telophase: Nuclear envelope begins to reform. animal cells: Cleavage in cell occurs which divides cell into two. plant cells: Cell wall forms in the middle of cell to separate the cell.

The phases in mitosis are prophase, metaphase, anaphase, and telophase. During prophase, the chromosomes condense and the nuclear envelope breaks down. In metaphase, the chromosomes line up at the center of the cell. In anaphase, the chromatids separate and move to opposite poles. Telophase involves the formation of new nuclear envelopes around the separated chromosomes.

Does the nuclear envelope re-forms during anaphase?
No, the nuclear envelope does not reform during anaphase. Instead, the nuclear envelope breaks down during prophase and prometaphase to allow the chromosomes to be free in the cytoplasm for segregation and reforms during telophase.
What disappears during prometaphase?
During prometaphase, the nuclear envelope breaks down, allowing the chromosomes to be released from the nucleus. The nuclear membrane disappears, leading to the chromosomes being able to interact with the mitotic spindle fibers for proper alignment and separation during cell division.
