Reproduction and Cell Division Quiz

When complex plants are produced by cloning, which process is most directly involved?

• mitotic cell division

• meiotic cell division

• gamete production

• sperm cell fertilization

Answer explanation

When complex plants are produced by cloning, mitotic cell division is most directly involved in the process.

Answer explanation

When complex plants are produced by cloning, mitotic cell division is most directly involved in the process.

If a lobster loses a claw, it is capable of growing a new one. What process makes this possible?

• sexual reproduction

• fertilization

• meiosis

• mitosis

Answer explanation

The process that allows a lobster to grow a new claw after losing one is mitosis, which is the division of a single cell into two identical daughter cells.

Organisms that reproduce asexually usually do so by a form of cell division called

• meiosis

• gamete formation

• mitosis

• sperm formation

Answer explanation

Organisms that reproduce asexually usually do so by a form of cell division called mitosis, making it the correct choice.

A normal body cell of a fruit fly contains eight chromosomes. Each normal gamete of this organism contains

• four chromosomes as a result of meiosis

• four chromosomes as a result of mitosis

• eight chromosomes as a result of meiosis

• eight chromosomes as a result of mitosis

Answer explanation

During meiosis, the number of chromosomes is halved, so each normal gamete of the fruit fly contains four chromosomes as a result of meiosis.

The process of mitotic cell division normally results in the production of

• four cells with half the number of chromosomes as the parent

• two cells with the same number of chromosomes as the parent

• two cells with only one chromosome from each parent

• one cell with a replicated set of matched chromosomes

Answer explanation

The correct answer is 'two cells with the same number of chromosomes as the parent' because mitotic cell division results in the formation of two daughter cells with the same number of chromosomes as the parent cell.

Each of the two daughter (or offspring) cells that result from the normal mitotic division of the original parent cell contains

• the same number of chromosomes but different genes than the parent cell

• the same number of chromosomes and genes identical to those of the parent cell

• one half of the number of chromosomes but different genes than those of the parent cell

• one half of the number of chromosomes and genes identical to those of the parent cell

Answer explanation

During normal mitotic division, each daughter cell contains the same number of chromosomes and genes identical to those of the parent cell.

All types of asexual reproduction involve the process known as

• mitosis

• fertilization

• meiotic division

• aging

Answer explanation

All types of asexual reproduction involve the process of mitosis, where a single cell divides into two identical daughter cells.

How many cells will finally be produced? How many chromosomes will be in each cell? Sketch one of the final cells, showing its chromosomes.
