the total of all the pigments wavelength. Introduction Photosynthesis is a process by which plants use the sunlight to convert it from light energy into chemical energy. This equation shows us how it is done‚ 6CO2 + 6H2O + light energy --> C6H12O6 + 6O2. The pigments called chlorophylls in the plants are what trap the light energy. Carotenoids also help aid the chlorophylls by also absorbing light. The two chlorophylls found in green plants are chlorophyll a and chlorophyll b. The purpose of

and water‚ producing glucose and oxygen. This process is extremely vital as it the major source of nutrition for all living things on Earth‚ and fuel organisms’ activities. The equation of photosynthesis is as follows: 6CO2 + 6H2O C6H12O6 + 6O2 Background: The Hydrilla verticillita is a considered a very oppurtunistic organism as it has been found at various locations‚ having taken over waters.

Midterm Study Guide Answers 1. A hypothesis is an explanation of observations. “If the floor is wet‚ I will slip.” 2. A controlled experiment is when only one variable is changed. 3. If the plant you are experimenting with has a disease that is an unavoidable experimental error. 4. An enzyme speeds up reactions and lowers the energy it takes to produce something‚ a lock and key. 5. Autotrophs make their own food by producing sugars from sunlight and various chemicals. 6
