Mitosis quiz for open day

What is the main purpose of mitosis?

• To produce energy for the cell

• To produce two genetically identical daughter cells

• To create genetic variation

• To carry out photosynthesis

Answer explanation

The main purpose of mitosis is to produce two genetically identical daughter cells, ensuring that each new cell has the same genetic material as the original cell, which is crucial for growth and tissue repair.

Why is mitosis important for multicellular organisms?

• Mitosis is primarily responsible for nutrient absorption.

• Mitosis leads to genetic variation in offspring.

• Mitosis is important for growth, repair, and maintaining genetic consistency in multicellular organisms.

• Mitosis is only important for single-celled organisms.

Answer explanation

Mitosis is crucial for multicellular organisms as it enables growth, repairs damaged tissues, and ensures genetic consistency across cells, maintaining the organism's overall health and functionality.

During which stage of mitosis do the chromosomes line up at the equator of the cell?

• Anaphase

• Telophase

• Prophase

• Metaphase

Answer explanation

During mitosis, chromosomes line up at the cell's equator during Metaphase. This alignment is crucial for ensuring that each daughter cell receives an identical set of chromosomes.

Fill in the blank,

The division of the cytoplasm AFTER mitosis is called ___________.

Answer explanation

The division of the cytoplasm after mitosis is called cytokinesis. This process ensures that the two daughter cells receive the necessary organelles and cytoplasmic components to function properly.

Cytokinesis is part of The Mitotic Cell Cycle.

• True

• False

Answer explanation

Cytokinesis is indeed part of the Mitotic Cell Cycle, occurring after mitosis to divide the cytoplasm and form two daughter cells. Therefore, the statement is true.

What is a tumor?

• A tumor is a type of cancer that only occurs in the brain.

• A tumor is what forms during metaphase of mitosis.

• A tumor is an organelle found in plant cells.

• A tumor is an abnormal growth of tissue caused by uncontrolled cell division.

Answer explanation

A tumor is defined as an abnormal growth of tissue resulting from uncontrolled cell division. This distinguishes it from the incorrect options, which misrepresent tumors as specific to cancer, mitosis, or organelles.
