Plant Transport Plants are mostly made up of water. Lettuce is about 94% water and a potato is about 77% water. Plants need water for three main purposes: ------photosynthesis‚ -support -transport of chemicals Water is a raw material for photosynthesis. If water is in short supply‚ the rate of photosynthesis will be limited. Plants need water for support‚ otherwise they wilt. Water is needed to transport many chemicals within plants. Chemicals‚ such as mineral salts‚ dissolve in water and

Infrared Spectroscopy is a very powerful technique used in the determination of molecular structure and the identification of unknown organic materials. The infrared spectrum yields direct information about the presence or absence of key functional groups. "The region of the infrared spectrum which is of greatest interest to organic

this lab was to separate plant pigments using chromatography‚ calculate Rf values using the collected data‚ and study photosynthesis with isolated chloroplasts. Light energy Light energy Background Information (Activity A): In photosynthesis‚ plant cells convert light energy into chemical energy that is stored in sugars and other organic compounds. It is an endergonic and anaerobic reaction. Critical to the process is chlorophyll‚ the primary photosynthetic pigment in chloroplasts. The chemical
