All resources for B1.4 Photosynthesis GCSE OCR Biology Gateway 9-1. Triple and combined (Higher and Foundation) is covered in this material. Each PowerPoint is a whole lessons included with student activities and animated answers. Word and symbol equation for photosynthesis. Carbon dioxide diffuses from the air through the stomata. Water travels by osmosis through the root hair cells. Photosynthesis occurs inside the plant’s chloroplast. Chloroplasts contain a green pigment called chlorophyll. Photosynthesis is an endothermic reaction. The two main stages of photosynthesis. Comparing photosynthesis and aerobic respiration. The positive test for starch Experimental procedure for testing starch in leaves. Testing for the need of chlorophyll for photosynthesis. Testing for the need of light for photosynthesis. Testing for the need of carbon dioxide for photosynthesis. Testing oxygen produced via photosynthesis. Testing light intensity affects photosynthesis. Definition for rate of photosynthesis The rate of photosynthesis affects the rate of biomass Limiting factors include, light level, carbon dioxide concentration, and temperature. Graphs for rate of photosynthesis against light level, carbon dioxide concentration, and temperature. Plotting data graphs. Experimental procedures to investigate how the rate of photosynthesis is affected by: Light level Temperature Carbon dioxide concentration Inverse square law for relative light intensity
