Cell Division (Part 3)

A cell can divide into two or more cells through a process called cell division. A cell may divide by mitosis or by meiosis depends on the type of cell being formed.

This quiz will teach you the terms related to cell division as well as its processes and functions.

  • Question of

    A special type of cell division in the formation of egg and sperm cells.

    • Meiosis
    • Cell Cycle
    • Mitosis
    • Cytokinesis

    Correct Wrong

    During meiosis, sexually reproducing organisms divide their cells to produce gametes, such as sperm or egg cells. There are two rounds of division that result in only one copy of each chromosome in four cells (haploid).

  • Question of

    In all living things, this molecule carries genetic instructions.

    • Deoxyribonucleic Acid
    • Microtubule
    • Chromosome
    • Cytoskeleton

    Correct Wrong

    All living things possess a molecule called deoxyribonucleic acid that contains the genetic instructions. Two DNA strands wind around each other to form a shape called a double helix. The backbone of each strand is comprised of alternating sugars (deoxyribose) and phosphate groups.

  • Question of

    The DNA and proteins that make up a chromosome.

    • Chromatin
    • Ribonucleic acid (RNA)
    • Centromere
    • Homologs

    Correct Wrong

    Chromatin is a material made up of DNA and protein that makes up chromosomes. Chromatin contains major proteins called histones, which act as packaging components for DNA. Chromatin is important because it's a good packing trick for getting all the DNA into a cell.

  • Question of

    A disc-shaped protein structure where the spindle fibers attach during cell division.

    • Kinetochore
    • Asters
    • Ribonucleic acid (RNA)
    • Cytoskeleton

    Correct Wrong

    A kinetochore is a disc-shaped protein structure where the spindle fibers attach during cell division to pull sister chromatids apart. The kinetochore assembles on the centromere and links the chromosome to microtubule polymers from the mitotic spindle during mitosis and meiosis.

  • Question of

    These organisms contain nuclei enclosed in a nuclear envelope.

    • Eukaryotes
    • Gene
    • Microtubule
    • Chromatin

    Correct Wrong

    The nucleus of eukaryotic cells is enclosed in a nuclear envelope. A typical eukaryotic cell contains membrane-bound organelles like mitochondria and the Golgi apparatus. Plants and algae typically have chloroplasts as well.

  • Question of

    The first phase of mitosis and meiosis.

    • Prophase
    • Interphase
    • Anaphase
    • Telophase

    Correct Wrong

    Mitosis and meiosis both begin with prophase, the first phase of cell division. After interphase, DNA has already been replicated when the cell enters prophase.

  • Question of

    An ensemble of proteins that support a cell’s structure.

    • Cytoskeleton
    • Ribonucleic acid (RNA)
    • Gamete
    • Telomere

    Correct Wrong

    A cytoskeleton is a group of fibrous proteins that provide structural support for cells, but this is only one of the functions of the cytoskeleton. Cytoskeletal components are also critical for cell motility, cell reproduction, and transportation of substances within the cell.

  • Question of

    A cytoskeleton that facilitates the movement of material within cells by motor proteins that adhere to the surface of the microtubules.

    • Microtubule
    • Homologs
    • Eukaryotes
    • Telomere

    Correct Wrong

    Microtubules are one type of filament system in eukaryotic cells. Motor proteins on the surface of microtubules facilitate the movement of material within cells via the microtubule cytoskeleton.
