Biology Cambridge IGCSE Course – Code 0610 and 0970: Topic 6 – Plant Nutrition

Course Description:

Welcome to our Biology Cambridge IGCSE course, meticulously tailored to help you conquer the intricacies of Topic 6: Plant Nutrition. This comprehensive course is specifically designed for both Code 0610 and Code 0970 syllabi, ensuring you’re well-prepared for the IGCSE Biology examination.

Course Highlights:

Comprehensive Core and Supplement Objectives: Master all core and supplement objectives as outlined in the syllabus for theory (papers 1, 2, 3, 4). These objectives provide a solid foundation for exam success.
Thoroughly Explained Experiments: Gain a deep understanding of practical experiments with detailed explanations. Notes summarize the method, results, interpretation, evaluation, reliability, and conclusion, enabling you to excel in paper 6 questions.

Course Outline & Objectives (Core and Supplement):

Photosynthesis (Lesson 1): Key objectives include:

Describe photosynthesis as the process by which plants synthesize carbohydrates from raw materials using energy from light.
State the word equation for photosynthesis as: carbon dioxide + water → glucose + oxygen in the presence of light and chlorophyll.
State that chlorophyll is a green pigment that is found in chloroplasts.
State that chlorophyll transfers energy from light into energy in chemicals, for the synthesis of carbohydrates
Outline the subsequent use and storage of the carbohydrates made in photosynthesis, limited to: (a) starch as an energy store (b) cellulose to build cell walls (c) glucose used in respiration to provide energy (d) sucrose for transport in the phloem (e) nectar to attract insects for pollination.
Explain the importance of: (a) nitrate ions for making amino acids (b) magnesium ions for making chlorophyll.
State the balanced chemical equation for photosynthesis as: 6CO2 + 6H2O → C6H12O6 + 6O2.
Identify and explain the limiting factors of photosynthesis in different environmental conditions.

Leaf Structure (Lesson 2): Key objectives include:

State that most leaves have a large surface area and are thin and explain how these features are adaptations for photosynthesis.
Identify in diagrams and images the following structures in the leaf of a dicotyledonous plant: chloroplasts, cuticle, guard cells and stomata, upper and lower epidermis, palisade mesophyll, spongy mesophyll, air spaces, vascular bundles, xylem, and phloem.
Explain how the structures listed in 2 adapt leaves for photosynthesis.

Experiment – Is Chlorophyll Necessary for Photosynthesis? (Lesson 3): Key objectives include:

To investigate whether chlorophyll is necessary for photosynthesis.

Experiment – Is Light Necessary for Photosynthesis? (Lesson 4): Key objectives include:

To investigate whether light is necessary for photosynthesis.

Experiment – Is Carbon Dioxide Necessary for Photosynthesis? (Lesson 5): Key objectives include:

To investigate whether carbon dioxide is needed for photosynthesis.

Experiment – How will Gas Exchange of a Plant be Affected by Being Kept in the Dark and in the Light? (Lesson 6): Key objectives include:

To investigate and describe the effect of light and dark conditions on gas exchange in an aquatic plant using hydrogen carbonate indicator solution.

Experiment – What is the Effect of Changing Light Intensity on the Rate of Photosynthesis? (Lesson 7): Key objectives include:

To investigate the effect of light intensity on the rate of photosynthesis.

Experiment – What is the Effect of Changing Carbon Dioxide Concentration on the Rate of Photosynthesis? (Lesson 8): Key objectives include:

To investigate the effect of carbon dioxide concentration on the rate of photosynthesis.

Experiment – The Importance of Different Mineral Ions for Plant Growth (Lesson 9): Key objectives include:

To investigate the importance of different mineral ions for plant growth.
