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

Introduction Photosynthesis is a process that is essential for every living organism. Organic substances, such as glucose, are made from carbon dioxide and water by light energy from the sun. The light energy is absorbed by chlorophyll and converted to chemical energy. During the process, oxygen is released as a by-product. The rate of photosynthesis is affected by a few of factors, including light intensity, temperature, availability of water and carbon dioxide concentration. The purpose of this experiment was to…...

Rate of Photosynthesis in Spinach leafs

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…...

C4 and CAM Plants

Many plant species that evolved in hot, dry climates fix carbon through alternative pathways. Under hot and dry conditions, plants can rapidly lose water to the air through small pores called stomata. Stomata (singular, stoma), are usually located on the undersurface of the leaves. Plants can reduce water loss by partially closing their stomata when the air is hot and dry. Stomata are the major passageways through which CO2 enters and O2 leaves a plant. When a plant’s stomata are…...
