Photosynthesis - Free Essay Examples and Topic Ideas

The photosynthetic pigment is used to absorb light during the process of photosynthesis. There are five pigments usually found in spinach leaves: Carotene (yellow), Phaeophytin (yellow-grey), Xanthophyll (yellow-brown), Chlorophyll a (blue-green), Chlorophyll b(green). Photosynthetic pigment is located in the chloroplast of the leaf. The function of chlorophyll a and chlorophyll b is to trap red and blue violet light when they carry out photosynthesis, chlorophyll a occurs in green plants while chlorophyll b occurs in green algae.Carotene and Xanthophyll are…

Research Question: How does the concentration of carbon dioxide affect the rate of photosynthesis in spinach leafs? Introduction: Spinach is a eukaryotic photoautotroph, contains plant cells and appears to be green, this suggests that it contains chlorophyll given that chlorophyll reflects green light (Mazia & Tyler, 1963). Photoautotrophs are organisms that use photosynthesis to sustain themselves with nutrients (Cavendish, 2004). In plant cells photosynthesis takes place in the chloroplast, it is a process where photoautotrophs use pigments in order to capture energy from visible light referred to as photons, these autotrophs also need carbon dioxide and water in order to produce…
