In this article, we will be discussing the significance and relationship between the size of the seeds and the plant processes involved as well as how these concepts can be tested in examinations. Furthermore, I will be sharing about the importance of linking the various Science concepts in our thought processes.<\/p>\n

    Let us start with a simple question:<\/p>\n

    \n

    How does the size of the seed affect a plant?<\/p>\n<\/blockquote>\n

    To be able to answer this question, students will need to be able to identify the keyword in the question above \u2013 What does it mean by the word, \u201caffect<\/strong><\/span>\u201d?<\/p>\n

    My answer to this would be for your child to start his\/her analysis of this question from the key processes<\/u> that take place in a plant.<\/p>\n

     <\/p>\n

    Key Processes in Plants<\/span><\/h2>\n
      \n
    1. Germination<\/li>\n
    2. Respiration<\/li>\n
    3. Photosynthesis<\/li>\n

    5. Fertilisation<\/li>\n
    6. Dispersal of Seeds\/Fruits<\/a><\/li>\n
    7. Transpiration<\/a><\/li>\n<\/ol>\n

      Next, we need to draw the linkage between these key plant processes and our understanding of plant parts<\/a> and what they do.<\/p>\n

       <\/p>\n

      Let Us List Down What We Have Learnt For Recap<\/span><\/h2>\n

      Plant Parts And Their Functions<\/span><\/h3>\n

      #1 Leaf<\/strong><\/p>\n

      \u00a0– Stomata: To allow the plant to carry out gaseous exchange.<\/p>\n

      #2 Stem<\/strong><\/p>\n

      – Food-carrying tubes: Transports food from the leaves upwards and downwards to all parts of the plant.<\/p>\n

      – Water-carrying tubes: Transports water from roots upwards to all parts of the plant.<\/p>\n

      *Do note that these tubes are found throughout the plant but commonly tested with the stem.<\/em><\/p>\n

      #3 Roots<\/strong>: Grow downwards to anchor the plant firmly to the ground and to absorb water and mineral salts<\/p>\n

      #4 Seed<\/strong><\/p>\n

      – Seed leaves: Contains food for respiration to release energy until the true leaves are formed.<\/p>\n

      #5 Flowers<\/strong><\/p>\n

      – Stigma: Allows the pollen grains to land on it for pollination to take place.<\/p>\n

      – Ovary: Contains ovules and develops into a fruit after fertilisation.<\/p>\n

      – Ovule: Contains ovum (egg) and develops into a seed after fertilisation.<\/p>\n

      – Anther: Produces and stores pollen grains.<\/p>\n

      – Filament: Holds the anther upright.<\/p>\n

      Is your child able to confidently describe the function of each part of the plant mentioned above? These basic functions of the plant should be at your child’s fingertips before taking any examination or test. \ud83d\ude42<\/p>\n

      Since the question mentions the\u00a0size of the seed<\/span>.\u00a0I will be\u00a0focusing<\/em> on the seed leaves that are stored in the seed<\/span>.<\/p>\n

      Think about it: What is the function of the seed leaves?<\/em><\/p>\n

      The seed leaves contain food, which is used together with oxygen in the process of respiration to release energy for the seedling.<\/p>\n

      The energy is used for the growth of the seedling until its true leaves are formed.\u00a0<\/strong>Why is that so?<\/p>\n

      The true leaves contain chloroplasts, which contain chlorophyll to trap sunlight in the process of photosynthesis to make food for the plant. Once the plant is able to make its own food, it no longer needs to depend on the food stored in the seed leaves for its survival.<\/p>\n

      What will happen to the seed leaves then?<\/p>\n

      The seed leaves will wither and drop.<\/p>\n

       <\/p>\n

      Conclusion<\/span><\/h2>\n

      Having established the facts above, what can you tell me about the importance of the size of the seed?<\/p>\n

      If your child has understood the thought process mentioned above, he\/she would most probably be thinking that a larger seed would have larger seed leaves. This would allow the seedling to depend on the food found in its seed leaves for a longer period of time<\/span> before its true leaves are formed.<\/p>\n

      This would increase the chances of survival for any young plant as some seeds germinate in areas with little light available. By allowing the plant to depend longer on its seed leaves, the seedling can fully develop its true leaves to trap sufficient light<\/span> for photosynthesis to make its own food, increasing its chances of survival.<\/p>\n

      What if we carry out an experiment in the dark with seeds of different sizes?<\/p>\n

      We can expect that the seedling that germinated from the larger seed<\/span> would be able to survive without sunlight\u00a0for a longer period<\/span> of time before withering and dying. This applies to seeds that come from the same species.<\/p>\n

      I hope that this sharing has helped your child to gain a better understanding of plants and how plants have adapted to survive in its natural environment.<\/p>\n

      In my next post, I will be sharing differences between self-pollination and cross-pollination<\/a>. In addition, I will also be covering the common misconceptions that students typically have on these two concepts.<\/p>\n

      Stay tuned to find out more!<\/p>\n

      (Disclaimer: This blog post has been written under the premise that students are expected to interpret the question based on the function of the seed leaves.)<\/em><\/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
