In this article, we will be discussing the transport system in Plants<\/strong><\/a> which is another concept commonly tested in examinations.<\/p>\n

Questions on the plant transport system typically test students on what would happen if the food-carrying tubes and\/or the water carrying tubes are removed. Such questions vary based on changing the positions where the tubes are removed.<\/p>\n

    For instance:<\/p>\n

    \n

    How do we determine the position of the swelling at the stem when the food carrying tube (phloem) is removed at different positions?<\/p>\n<\/blockquote>\n

     <\/p>\n

    Background<\/span><\/h2>\n

    Firstly, let us take a look at the functions and the positions of the tubes in the stem.<\/p>\n

    \"\"<\/p>\n

    Your child may have some problems remembering the positions of the phloem and the xylem. Over at The Pique Lab<\/span><\/a>, we teach our students an acronym to help them retain these important distinctions:<\/p>\n

    \n

    The acronym, \u201cWIFO\u201d. denotes W<\/span>ater I<\/span>nside F<\/span>ood O<\/span>utside. An alternative way is that \u2018Foo<\/span>d<\/span>\u2019 has an O, which is also found in \u2018Phlo<\/span>em\u2019.<\/p>\n<\/blockquote>\n

     <\/p>\n

    Type A & Type B Questions<\/span><\/h2>\n

    Next, there are two typical variations of questions where the food-carrying tubes are cut:<\/p>\n

    \"\"<\/p>\n

    Students usually have no issues answering Type A question. However, many of the students tend to neglect the leaves at the bottom of the cut featured in Type B.<\/p>\n

    As such, these students tend to answer ‘Type B’ questions the same way as Type A, which is incorrect. There are different outcomes for Type A and Type B, but both require the same concept<\/span>.<\/p>\n

     <\/p>\n

    Here’s Why<\/span><\/h3>\n

    Food-carrying tubes, also known as phloem, carry food made from the leaves to other parts of the plant<\/a>.<\/p>\n

    When the food-carrying tubes are removed, food made by the leaves will not<\/span> be able to be transported to other parts of the plant.<\/p>\n

    This causes the food to accumulate at the cut, which results in the bulging of the stem.<\/p>\n

     <\/p>\n

    So What’s The Difference Between Type A & B?<\/span><\/h3>\n

    \"\"<\/p>\n

    The only difference between Type A and Type B questions lies in the number of bulges<\/span> in the stem.<\/p>\n

    Type A only has one bulge on the upper side of the cut. The reason is that the leaves are only found above the cut. Thus, the food made by the leaves above the cut cannot be transported down to the roots. Therefore, the food will accumulate, causing a bulge in the stem above the cut.<\/p>\n

    On the other hand for Type B, there are leaves above and below the cut. Hence, there will be a bulge above and below the cut. Food made by the leaves above the cut could not be transported down to the roots and would accumulate, causing a bulge in the stem above the cut. Similarly, food made by the leaves below the cut could not be transported up to the stem and branches, causing a bulge in the stem below the cut.<\/p>\n

     <\/p>\n

    In Conclusion…<\/span><\/h2>\n

    When your child answers questions on the plant transport system:<\/p>\n

    1) Always focus on the functions of the tubes to understand what will happen if they are removed.<\/p>\n

    2) Observe the diagram carefully in order to answer the questions accurately<\/a>.<\/p>\n

    In the next and final part of our series, I will be looking at 5 common questions and interpretations about Plants.<\/p>\n

    Today\u2019s Question:<\/span><\/h2>\r\n
    How Should The Bulb Be Connected To The Circuit For It To Light Up?<\/strong><\/span><\/blockquote>\r\n

    The following question is commonly encountered by students during tests.<\/p>\r\n

    \"\"<\/a>Question Credit: Anglo Chinese School (Junior)\/ 2015 Primary 5 SA1\/ Question 18<\/em><\/p>\r\nWe can see that the key difference between the four options is the connection of the bulb(s) in the circuit.\r\n

    Requirements Needed for a Bulb to Light Up<\/span><\/strong><\/h3>\r\n\u00a0\r\n\r\n\"\"<\/a>\r\n\r\n\u00a0\r\n\r\nOne wire is connected to the metal casing & one wire is connected to the metal tip<\/u><\/strong>\r\n\r\n\u00a0\r\n

    \"\"<\/a>Example of a closed circuit<\/em><\/p>\r\nWhen the wires in the circuit are connected to the metal casing and metal tip of the bulb, there is a closed (or complete) circuit with the bulb. Electricity will be able to flow through the filament, causing the bulb to light up.\r\n

    What Happens When Both Wires Are Connected To The Metal Tip\/Metal Casing?<\/strong><\/span><\/h2>\r\nScenario #1: Both wires are connected to the metal tip<\/strong><\/span>\r\n\r\n\"\"<\/a>\r\n

    Example of a circuit when the wires are connected only to the metal tip<\/em><\/p>\r\nWhen both wires are connected to the metal tip of the bulb, electricity is unable to flow through the filament, preventing the bulb from lighting up.\r\n\r\nScenario #2: Both wires are connected to the metal casing<\/strong><\/span>\r\n\r\n\u00a0\r\n

    \"\"<\/a>Example of a circuit when the wires are connected only to the metal casing<\/em><\/p>\r\nWhen both wires are connected to the metal casing of the bulb, electricity is unable to flow through the filament, preventing the bulb from lighting up.\r\n\r\nNow, let us now take a look at the question again.\r\n

    Analysis Of The Options<\/strong><\/span><\/h2>\r\n\"\"<\/a>\r\n\r\nWhen analysing the circuits, students need to take note of one key point:\r\n

    How is the bulb connected to the circuit?<\/strong><\/span><\/h3>\r\nIn the following analysis, I have traced the pathway that electricity flows through (in red) as well so that it is easier to understand why the bulb lights up.\r\n

    Circuit A<\/strong><\/span><\/p>\r\n\"\"<\/a>\r\n\r\nBoth the metal casing and tip of the bulb are connected to the circuit, forming a closed circuit. Thus, electricity is able to flow through the wires in the circuit to the filament, allowing the bulb to light up.\r\n

    Circuit B<\/strong><\/span><\/p>\r\n\"\"<\/a>\r\n\r\nOnly the tip is connected to the circuit. Thus, electricity is unable to flow through the filament, preventing the bulb from lighting up.\r\n

    Circuit C<\/strong><\/span><\/p>\r\n

    \"\"<\/a><\/p>\r\nOnly the casing is connected to the circuit. Thus, electricity is unable to flow through the filament, preventing the bulb from lighting up.\r\n

    Circuit D<\/strong><\/span><\/p>\r\n

    \"\"<\/a><\/p>\r\nBoth the metal casing and tip of the two bulbs are connected to the circuit, forming a closed circuit. Thus, electricity is able to flow through the wires in the circuit to the filaments, allowing the bulbs to light up.\r\n\r\nAs the bulbs in circuits A and D will light up, the correct answer is option 4.\r\n

    What We Have Learnt Today<\/strong><\/span><\/h2>\r\nWhen students wish to find out if the bulb will light up, they should check the following:\r\n

    Are both the metal casing and the tip of the bulb connected to the circuit?<\/span><\/strong><\/h3>\r\nIf the answer to the question is \u2018yes\u2019, the bulb will light up. :)\r\n\r\nIn the next blog post, I will be sharing about the advantages and disadvantages of arranging bulbs in series and in parallel.\r\n\r\nStay tuned! :)\r\n\r\n
