Cellular Reproduction

Your normal body cells contain 46 (23 pairs) total chromosomes. How many chromosomes do they have after mitosis is complete?

• 23

• 46

• 92

• only half

Answer explanation

After mitosis, the number of chromosomes in normal body cells remains the same. Since normal body cells start with 46 chromosomes, they still have 46 chromosomes after mitosis is complete.

Pick the correct function for mitosis

• growth & repair

• sexual reproduction

• genetic diversity

• variation of the species

Answer explanation

Mitosis is primarily responsible for growth and repair of tissues in multicellular organisms. It produces identical daughter cells, which is essential for replacing damaged cells and supporting overall growth.

Type of cells for mitosis

• sperm cells

• egg cells

• gametes

• body cells

Answer explanation

Mitosis occurs in body cells (somatic cells) for growth and repair, not in gametes (sperm and egg cells), which undergo meiosis. Therefore, the correct answer is body cells.

Type of cells that meiosis produces

• sperm and egg cells

• zygotes

• skin and bone cells

• blood cells and muscle cells

Answer explanation

Meiosis produces gametes, which are specialized cells for sexual reproduction. In humans, these are sperm and egg cells, making 'sperm and egg cells' the correct answer. Other options do not relate to meiosis.

The main advantage of meiosis and sexual reproduction is the creation of _____________ offspring.

• fewer

• more

• diverse

• cloned

Answer explanation

The main advantage of meiosis and sexual reproduction is the creation of diverse offspring. This genetic variation enhances adaptability and survival, unlike cloning, which produces identical offspring.

Which process creates 4 daughter cells?

• Meiosis

• Mitosis

• Both

• Neither

Answer explanation

Meiosis is the process that results in four daughter cells, each with half the number of chromosomes of the original cell. In contrast, mitosis produces two identical daughter cells. Therefore, the correct answer is meiosis.

Which process creates 2 identical daughter cells?

• Meiosis

• Mitosis

• Both

• Neither

Answer explanation

Mitosis is the process that results in two identical daughter cells, as it involves a single division of the nucleus and cytoplasm. In contrast, meiosis produces four genetically diverse cells, not identical ones.

What process helps a cut on your hand to repair itself over time?

• Meiosis

• Budding

• Mitosis

• Vegetative Propagation

Answer explanation

Mitosis is the process by which cells divide and replicate, allowing for the repair of tissues, such as a cut on your hand. This cellular division is essential for healing and regeneration.

Meiosis creates daughter cells with how many chromosomes?

• 46

• 12

• 92

• 23

Answer explanation

Meiosis reduces the chromosome number by half, resulting in daughter cells with 23 chromosomes each. This is crucial for sexual reproduction, ensuring that when gametes fuse, the total returns to 46.

Mitosis creates daughter cells with how many chromosomes?

• 46

• 12

• 92

• 23

Answer explanation

Mitosis results in two daughter cells, each with the same number of chromosomes as the parent cell. In humans, the parent cell has 46 chromosomes, so each daughter cell also has 46 chromosomes.
