The Cell (Part 1)

The cell is the smallest unit of life, performing all the functions needed to survive, including reproduction. Ultimately, cells make us human. So, today let’s look at some of the cell’s basic structures.

  • Question of

    The cytoplasm contains a network of membranes that assist in the synthesis of proteins.

    • Endoplasmic reticulum
    • Organelle
    • Vacuole
    • Intermediate filaments

    Correct Wrong

    Endoplasmic reticulum (ER) is an organelle composed of membrane-bound tubules responsible for synthesising proteins. Two types of endoplasmic reticulum (ER) exist: the rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER).

  • Question of

    Cellular structure that is responsible for one or more specific functions.

    • Organelle
    • Lipids
    • Cytoplasm
    • Peroxisome

    Correct Wrong

    Organelles are subcellular structures that perform one or more specific functions in a cell, much like organs do in the body. Cell organelles such as nuclei, which store genetic information, mitochondria, which produce chemical energy, and ribosomes, which assemble proteins, are of particular importance.

  • Question of

    Cell’s central organelle; contains the cell’s DNA

    • Nucleus
    • Adenosine triphosphate (ATP)
    • Cell membrane
    • Microfilaments

    Correct Wrong

    The nucleus is the cell’s central organelle; contains the cell’s DNA

  • Question of

    In between the membrane and the nucleus, this material holds the contents of the cell.

    • Cytoplasm
    • Centrosome
    • Cytoskeleton
    • Adenosine triphosphate (ATP)

    Correct Wrong

    A cell's cytoplasm is the material between its membrane and nucleus that holds its internal contents.

  • Question of

    Compounds that drive many processes in living cells.

    • Adenosine triphosphate (ATP)
    • Endoplasmic reticulum
    • Peroxisome
    • Lipids

    Correct Wrong

    The organic compound ATP is a hydrotrope that provides energy to many processes in living cells, such as muscle contraction, nerve impulse propagation, condensate dissolution and chemical synthesis.

  • Question of

    The “energy transformer” of the cell, it is membranous and bean-shaped.

    • Mitochondria
    • Golgi apparatus
    • Microfilaments
    • Lipids

    Correct Wrong

    The mitochondria are membrane-covered bean-shaped organelles that are the cell's "energy transformer."

  • Question of

    Are layers of membranes that function in modifying, sorting, and packaging of proteins for secretion.

    • Golgi apparatus
    • Vacuole
    • Cell membrane
    • Nucleus

    Correct Wrong

    Golgi apparatus are layers of membrane-bound sacs that function in modifying, sorting, and packaging proteins for secretion.

  • Question of

    The chemical reactions that sustain life in organisms.

    • Metabolism
    • Carbohydrate
    • Secretory vesicles
    • Ribosomes

    Correct Wrong

    The metabolic process is the set of chemical reactions that sustain life in an organism.

  • Question of

    A membrane-bound cell organelle, generally small, and help sequester waste products.

    • Vacuole
    • Endoplasmic reticulum
    • Metabolism
    • Microfilaments

    Correct Wrong

    A vacuole is a membrane-bound cell organelle, generally small, and help sequester waste products.

  • Question of

    Are minute particles consisting of RNA and associated proteins that function to synthesize proteins.

    • Ribosomes
    • Protein
    • Centrosome
    • Intermediate filaments

    Correct Wrong

    Ribosomes are tiny particles composed of RNA and proteins that synthesize proteins.
