BIOLOGY LAB REPORT NAME :princess cucumber TOPIC : 3.8 & 8.2 : PHOTOSYNTHETIC PIGMENTS RESEARCH QUESTION INTRODUCTION The photosynthetic pigments are responsible for absorbing and trapping light energy the major pigments of photosynthesis are the chlorophylls. The two chlorophylls found in green plants are chlorophyll a and chlorophyll b. other pigments include carotenoids and phycobilins‚ sometimes referred to as accessory pigments. Carotenoids occur in all photosynthetic organisms‚ while

Photosynthesis Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. The equation for photosynthesis: Carbon Dioxide + Water (+ Light Energy) → Glucose + Oxygen Symbol equation: 6CO2 + 6H2O ------> C6H12O6 + 6O2 (http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa_pre_2011/plants/plants1

Roberts Energy‚ Metabolism‚ and Cells Photosynthesis is the process that pretty much every organism on earth needs‚ because of the nutrients produced which is needed in order to live. Plants capture the energy from the sun and converts it into food that is needed by all plants and animals (including us as humans). In this process the chemical reaction which is known as photosynthesis‚ it takes the sun’s energy and chlorophyll found in chloroplasts in the green leaves of plants‚ to turn inorganic

they are very small and do not need energy. 2. a) Root hair cells are found at the root of plants. They help plants to absorb water and mineral ions from soil efficiently. Mesophyll cells are found in leaves. They carry out gas exchange and photosynthesis in plants. b) Root hair cells are adapted to increase the rate of diffusion of water and mineral ions from soil to be as quick as possible. The
