  1. Printable animal cell diagram to help you learn the organelles in an animal cell in preparation for your test or quiz. 5th grade science and biology.

    • Definition of Mitochondria
    • Structure of Mitochondria
    • Functions of Mitochondria
    These are membrane-bound organelles located in the cytoplasm of all eukaryotic cells
    The number of mitochondria found in each cell varies widely depending on the function of the cell it performs.
    For example, erythrocytes do not have mitochondria while the liver and muscle cells have thousands of mitochondria.
    They are rod-shaped or oval or spherically shaped, with a size of 0.5 to 10 μm.
    Mitochondria have two special membranes – outer and inner membrane.
    They have a mitochondrial gel-matric in the central mass.
    The membranes bend into folds known as cristae.
    Their primary function is to generate energy for the cell i.e they are the power generators, producing energy in form of Adenosine Tri-phosphate (ATP), by converting nutrients and oxygen into energ...
    Mitochondria also store calcium which assists in cell signaling activity, generating cellular and mechanical heat and mediating cellular growth and death.
    The outer membrane is permeable, allowing the transport of small molecules and a special channel to transport large molecules.
    The inner mitochondrial membrane is less permeable thus allowing very small molecules into the mitochondrial gel-matrix in the central mass.  The gel matrix is composed of the mitochondria DNA and...

  3. Cell Diagrams with Labelling Activity. I've created two interactive diagrams for an upcoming open textbook for high-school level biology. The cell structure illustrations for these diagrams were generated in BioRender. Both diagrams feature a drag-and-drop labelling activity created with H5P here on Learnful.

  4. Aug 20, 2022 · Animal cells are of various shapes and sizes. Their sizes range from micrometers to a few inches. The smallest cell in the animal is a neuron that is just 100 micrometers in diameter. Likewise, the largest cell is the egg of an ostrich that can be up to 150 millimeters in diameter and weigh about 3 pounds.

  6. An egg cell is a cell found in female animals which is essential for producing offspring. It provides half of the genetic information needed to make another of the species and needs to be fertilised by a male sex cell to produce offspring.
