Asexual and Sexual Reproduction Science

What is the primary goal of Mitosis?

• Sexual reproduction

• Growth and repair

• Meiosis

• Just the division of cells for good measure

What is the primary goal of Meiosis

• Sexual reproduction

• Asexual reproduction

• Growth and repair

• Mitosis

What occurs in Mitosis?

• In mitosis, you have two phases of PMAT(prophase, metaphase, anaphase, and telophase), and it becomes four different daughter cells. There are 23 chromosomes. Sperm cells in males and egg cells in females.

• In mitosis, you have one phase a PMAT(prophase, metaphase, anaphase, and telophase), and you have two identical cells with 46 chromosomes. They are somatic cells.

What happens in Meiosis?

• In meiosis, you have one phase a PMAT(prophase, metaphase, anaphase, and telophase), and you have two identical cells with 46 chromosomes. They are somatic cells.

• In meiosis, you have two phases of PMAT(prophase, metaphase, anaphase, and telophase), and you have four different cells with 23 chromosomes which are sperm cells in males and egg cells in females

What happens in prophase(mitosis)?

• In prophase, the chromosomes condense and become visible. The nuclear membrane and the nucleolus disappear.

• In prophase, the chromosomes line up in the middle of the cell.

• In prophase, the chromosomes are pulled away by the spindles which are held by centrioles which retract the chromosomes apart and to the opposite sides of the cell.

• In prophase, two new nuclei form and you can see that two new cells are forming.

What happens in interphase?

• In interphase, the cell spends 75% of its life replicating its chromosomes.

• In interphase, the cell spends 90% of its life replicating its mitochondria.

• In interphase, the cell spends 90% of its life replicating its DNA.

• In interphase, the cell spends 10% of its life replicating itself.

What is metaphase(mitosis)?

• In metaphase, the chromosomes split apart do to the retraction of the spindles which connect to centromeres and go to opposite sides of the cell.

• In metaphase, the cell finally splits in two, ready to help the body grow and replace lost cells.

• In metaphase, the chromosomes now line up in a single file line in the center of the cell.

• In metaphase, the chromosomes line up in pairs in the center of the cell.

What happens in anaphase(mitosis)?

• In anaphase, the chromosomes duplicate creating 92 chromatids and divides into two, fresh, cells.

• In anaphase, the chromosomes now split apart to chromatids due to the retraction of the spindles which are held by centromeres and go to opposite sides of the cell.

• In anaphase, the chromosomes condense and line up with their homologues pairs and do something called crossing over which exchanges their genetic material making them different.

• In anaphase, the cell leaves the body to go to another body and duplicate again. A FOR AWAY.

What is telophase(mitosis)?

• In telophase, two new nuclei form around the chromosomes and it is obvious that the cell is going to divide into two.

• In telophase, the cell spends ninety percent of its life getting ready to go to metaphase.

• In telophase, the chromosomes condense and are now visible to see.

• In telophase, the chromosomes split apart and retract due to spindles attached to centromeres and the chromosomes move to opposite sides of the cell.

What is cytokinesis?

• Cytokinesis is when the cell finally doubles in size by two.

• Cytokinesis is when the cell finally divides into two.

• Cytokinesis in when the cell finally divides into four.
