scientific calculations

• Plants make their own food using photosynthesis.
• The food that plants produce is important, not only for the plants themselves, but for the other organisms that feed on the plants.
• The importance of limiting factors in photosynthesis is emphasized in the higher required practical activity.
• Photosynthesis is a process that affects Bioenergetics.
• Scientific calculations are a part of the higher required practical activity for limiting the rate of photosynthesis.
• The table shows a set of results obtained by students investigating the effect of light intensity on photosynthesis.
• Factors that affect photosynthesis include distance from the light source.
• The students varied the distance of the plant from the light source in their investigation.
• Scientific calculations are a part of the higher required practical activity for understanding the importance of limiting factors in photosynthesis.
• Limiting the rate of photosynthesis involves higher required practical activity.
• The graph of the data obtained in the investigation shows that the rate of oxygen production at 18 cm from the light source is 40 bubbles per minute.
• Biology (Single Science) includes a topic on Bioenergetics.
• The rate of photosynthesis is measured in terms of the number of bubbles produced per minute.
