    This assignment is for you if you are HL Bio and
    a 12th grader in September 2018.



    IB Biology HL Summer Homework 2: Drawings

     

    Practice your science diagram drawing skills this summer. Complete the required drawings listed on the next page to turn in on the FIRST day of school. Use you online resources. You may enhance your drawings with color for your own benefit but understand that the drawings you complete on you IB exam will be in a single pen color.

     Here are two examples of BAD drawings:

    ASSESSMENT STATEMENT

    TEACHER’S NOTES

    SL DRAWINGS

    1.2.1

    Draw and annotate a diagram of the ultrastructure of Escherichia coli (E. coli).

    The diagram should show the cell wall, plasma membrane, cytoplasm, pili, flagella, ribosomes and nucleoid (region containing naked DNA).

    1.2.2

    Draw and annotate a diagram of the ultrastructure of a liver cell.

    The diagram should show free ribosomes, rough endoplasmic reticulum (rER), lysosome, Golgi Apparatus, mitochondrion and nucleus.

    The Golgi Apparatus will be used in place of the Golgi body, Golgi complex, or dictyosome.

    1.3

    Draw and label a fluid mosaic model to show the structure of membranes.

    The diagram should show the phospholipid bilayer, cholesterol, glycoproteins, integral, and peripheral proteins. Use the term plasma membrane, not cell surface membrane for the membrane surrounding the cytoplasm. Integral proteins are embedded in the phospholipid of the membrane, whereas peripheral proteins are attached to its surface. Variations in composition related to the type of membrane are not required.

    2.1

    Draw molecular diagrams of glucose, ribose, a saturated fatty acid and a generalized amino acid.

     

    2.4

    Draw molecular diagrams to show the formation of a peptide bond.

     

    2.6

    Draw simple diagrams of the structure of single nucleotides of DNA and RNA, using circles, pentagons, and rectangles to represent phosphates, pentoses, and bases.

    An extension of the diagram in 2.6 is to show the complementary base pairs of A-T and G-C, held together by hydrogen bonds and the sugar-phosphate backbones. The number of hydrogen bonds between pairs and the details of purine/pyrimidines are not required.

    2.9

    Draw an absorption spectrum for chlorophyll and an action spectrum for photosynthesis.

     

    3.3

    Draw and annotate diagrams to show the stages of meiosis resulting in the formation of four haploid cells.

     

    4.3

    Draw and label a diagram of the carbon cycle to show the processes involved.

    The details of the carbon cycle should include the interaction of living organisms and the biosphere through the processes of photosynthesis, cell respiration, fossilization, and combustion. Recall of specific quantitative data is not required.

    6.1

    Draw, label, and annotate a diagram of the digestive system.

    The diagram should show the mouth, esophagus, stomach, small intestine, large intestine, anus, liver, pancreas, and gall bladder. The diagram should clearly show the interconnections between these structures.

    6.6

    Draw and annotate diagrams of male and female reproductive systems to show names of structures and their functions.

    The relative positions of the organs is important. Do not include any histological details, but include the bladder and urethra.

    9.1

    Draw the structure of primary xylem vessels in sections of stems based on microscope images.

    Diagram should include cortex, epidermis, pith, vascular bundle (xylem, cambium, phloem).

    9.4.1

    Draw internal structure of seeds.

    Diagram should include seed coat, cotyledon, embryo shoot (plumule), embryo root (radicle).

    9.4.2

    Draw half-views of animal-pollinated flowers.

    Diagram should include stigma, style, anther, petal, filament, sepal, ovaries, and nectary.

    Annotations should include humerus, triceps, biceps, joint-capsule, synovial fluid, radius, ulna, cartilage, tendon

    11.2.2

    Draw labelled diagrams of the structure of a sarcomere.

    Diagram should include thick myosin filaments, thin actin filaments, light band, dark band, Z-line, sarcomere, myosin heads.

    11.3
