Introduction To Cell Reproduction: Mitosis And Meiosis! Trivia Questions Quiz

Interphase is comprised of G1, S, and G2 phases in that order.
G1 phase is characteristic of growth of the cell.
S phase is characteristic of DNA replication; the chromosomes are copied.
G2 phase is characteristic of continued growth and preparation of the cell for mitosis.

Interphase -> Prophase -> Metaphase -> Anaphase -> Telophase -> Cytokinesis

The four stages of the M-phase (Mitosis) have been expanded in this question.

Asexual reproduction occurs when one parent divides or gives rise to genetically identical offspring.

Binary fission is one of the seven types of asexual reproduction that are discussed in chapter 9. Binary fission is the simplest of asexual reproduction and is done by both bacteria and paramecium.

'A' identifies centrioles. Centrioles are used during cell division of animal cells.
'B' identifies the chromosome.
'C' identifies the spindle fibers that are used in moving chromosomes during cell division.

The cell cycle includes: Interphase, Mitosis, and Cytokinesis. Of these three stages, a cell spends an estimated 90% of its life cycle in Interphase.

'A' identifies an entire chromosome.
'B' identifies a centromere. A centromere holds two sister chromatids together.
'C' identifies a chromatid.
'D' identifies homologous chromosomes. Homologous chromosomes paired together form a tetrad.

Cytokinesis is the stage in the cell cycle in which a dividing cell is finally split into two daughter cells that immediately reenter Interphase.

During Anaphase, sister chromatids are separated at their centromere and pulled to opposite poles of the dividing cell.

Budding is one of the seven examples of asexual reproduction discussed in chapter 9. Budding is carried out when cells grow on the parent organism and eventually pinch off and fall to the surface. Once on the surface, these cells grow an organism identical to the parent organism. Hydra, sea anemones and yeast are all examples of organisms that reproduce asexually by budding.

Telophase is indicated because one parent cell is dividing into two daughter cells. The daughter cells contain single chromatids and have not undergone crossing over.

Mitosis is the division of the nucleus. If a protein is preventing cell division, it would prevent the cell (nucleus) from dividing.
It would not prevent the cell from diffusing water across the membrane (osmosis), changing its DNA (mutation), or breaking down sugars to form usable energy (respiration).

Sexual reproduction is the process by which a male gamete and a female gamete join to form a new organism. The new organism will contain genetic material from both the male and female parent. Because this process requires two parents, it is slow and requires lots of energy.

By definition, Anaphase is characterized by the separation of sister chromatids at the centromere to opposite poles of the dividing cell.

Plant cells differ from animal cells in that during cytokinesis they must form a cell plate that functions to divide the cytoplasms of the two new daughter cells.

1. Telophase
2. Cytokinesis
3. Prophase
4. Interphase
5. Anaphase
6. Metaphase

Number 7 is pointing to the cell plate. Cell plates can only be found in plant cells.

The image depicts Prophase II. We know this because we are looking at two cells that contain visible chromosomes and the spindle fibers are just starting to form.

'A' identifies centrioles. Centrioles are used during cell division of animal cells. 'B' identifies the chromosome. 'C' identifies the spindle fibers that are used in moving chromosomes during cell division.

Interphase is the only stage in the cell cycle in which chromatin is visible. Looking at the nucleus, the chromosomes are in a relaxed form known as chromatin.

Mitosis is the process by which a parent cell gives rise to two genetically identical daughter cells. This process is done so that somatic cells can grow and repair damaged cells.

Meiosis is the process by which gametes (sex cells) are produced. Gametes are haploid, meaning they contain only half the number of chromosomes as the parent cell. If the parent cell has 20 chromosomes, the gamete produced by Meiosis will only have half of that number. The gamete will have 10 chromosomes.

Anaphase I is indicated because there is whole chromosome movement to the opposite poles of the dividing cell.

Although the G2 phase is part of Interphase, it is characteristic of cellular growth and preparation for mitosis.
The S phase of Interphase is characterized by replication of DNA.

In oogenesis, 1 ova (egg cell) is produced. Three polar bodies are also produced, but they are unusable and will be reabsorbed by the female.

Crossing over is the exchange of genetic material between homologous chromosomes that occurs during Prophase I or Meiosis I.

The cell cycle includes: Interphase, Mitosis, and Cytokinesis. Of these three stages, interphase and mitosis are the main stages. Although important, cytokinesis is not a main stage in the cell cycle.

Prophase is characterized by the nuclear membrane disintegrating, the centrioles moving to opposite poles and forming spindle fibers, as well as DNA condensing into the visible form (chromosomes).

4. Interphase
3. Prophase.
6. Metaphase
5. Anaphase
1. Telophase
2. Cytokinesis


Number 7 is pointing to the cell plate.

Telophase I is indicated because there is only one cell currently dividing into two. Also, we can definitively say that it is not "telophase" of mitosis because the crossing over event has occurred resulting in the two-toned chromosome color.

Meiosis is the process by which gametes (sex cells) are produced. Gametes are haploid, meaning they contain only half the number of chromosomes as the parent cell. The reason for this is because gametes from the male and female parents will join together to form a zygote (fertilized egg) that has a diploid number of chromosomes.

'A' identifies an entire chromosome. 'B' identifies a centromere. A centromere holds two sister chromatids together. 'C' identifies a chromatid. 'D' identifies homologous chromosomes. Homologous chromosomes paired together form a tetrad.

Meiosis is the process by which gametes (sex cells) are produced. Gametes are haploid, meaning they contain only half the number of chromosomes as the parent cell. If the parent diploid cell contains 30 chromosomes, then the gamete will contain half that and have 15 chromosomes.

Hydra reproduces via budding, which is a form of asexual reproduction. In budding, a small bud grows on the body of the parent organism and eventually detaches to become a new individual. This process allows for the rapid production of offspring without the need for a mate. Therefore, Hydra is the correct answer as it is the only organism listed that reproduces through budding.

G1, S, and G2 are the only answer choice that are part of Interphase. G1 is characteristic of doubling the cytoplasm of the parent cell; it has the most growth.

Vegetative propagation is the form of asexual reproduction in which plants with creeping roots will be able to sprout identical plants along the ground. This occurs in grasses, strawberry plants, and some potatoes.

Interphase contains the stages: G1, S, and G2
M phase represents either Mitosis (somatic cells) or Meiosis (gametes).

Chromosomes are only visible during the division of the cell (Mitosis). Chomatin condenses into visible chromosomes during prophase and then relaxes into chromatin during telophase.

Mitotic cell division (Mitosis) is characterized of producing two genetically identical daughter cells. Meaning, if your skin cells contain 46 chromosomes and they divide, the resulting two cells will also contain 46 chromosomes.
