Biology Tuition Singapore O Level Biology Tuition – Plant Nutrition Common Misconception   Misconception 1 Epidermal cells do not have chloroplasts. Therefore, they should not be classified as plant cells Correct Conception 1 Chloroplasts are not the only characteristic of plant cells. Different leaf cells are adapted in different ways to carry out photosynthesis efficiently. The lack of chloroplasts in epidermal cells enables more sunlight to penetrate into the inner mesophyll layers   Misconception 2 All plant cells have rigid cellulose cell walls. Hence, they are not able to change their shapes. Correct Conception 2 Not all plant cells are rigid in shape. Guard cells have a thicker cell wall near the stoma. This difference in thickness enables the guard cells to bend as ...

Physics Tuition Singapore O level Physics Tuition – Temperature Common Misconception   Misconception 1 Temperature is a vector quantity because it can have negative values similar to velocity Correct Conception 1 Temperature is a scalar quantity and not a vector quantity. A negative value for velocity means its direction is opposite of the defined positive direction. A negative value for temperature means its value is lower than zero   Misconception 2 Ice point is the temperature of ice and steam point is the temperature of steam. Correct Conception 2 Ice can have temperatures lower than 0°C and steam can have temperatures higher than 100°C. Therefore, this definition cannot provide fixed temperatures for calibration. The correct definition of ice point refers to the point ...

The precipitate dissolves in excess ammonia solution.   Misconception 2 All metal ions react with aqueous sodium hydroxide to form precipitates. Correct Conception 2 Metal ions, such as Na+ and KE, do not form precipitates with NaOH(aq).   Misconception 3 To test for Cl– ions, add hydrochloric acid, followed by silver nitrate solution. Correct Conception 3 HC1(aq) should not be used, as Cl– ...
