Green plants, in fact, have to make or rather synthesise the food they need and all other organisms depend on them for their needs. Green plants carry out ‘photosynthesis’, a physico-chemical process by which they use light energy to drive the synthesis of organic compounds.
Embedded in the thylakoid membrane are molecules of chlorophyll, a pigment (a molecule that absorbs light) through which the entire process of photosynthesis begins. Chlorophyll is responsible for the green color of plants.
What plant pigments are involved in photosynthesis? chlorophyll a, chlorophyll b, and carotenoids 5. Explain why chlorophyll appears green to us in terms of what happens to different wavelengths of light that strike a chlorophyll molecule. We see light that bounces off of objects (reflected light). Chlorophyll is best at trapping and absorbing ...
Here's a brief overview of the steps involved in photosynthesis to help you quickly grasp how the process works. Light is absorbed by chlorophyll, a ferment contained in leaves. Light energy is converted into chemical energy: light energy is used to split a water molecule. The reaction releases chemical energy.
23 sty 2019 · Summarize the overall purpose of photosynthesis, as well as its inputs and outputs. Describe the structures used to perform photosynthesis in plants. Describe the main components of the light reactions and Calvin cycle, and how they contribute to photosynthesis.
Student Worksheet. 2. On Diagram 5, fill in the labels with the following descriptions to show the connections between the light reactions and the Calvin cycle. • carbon dioxide (CO 2) • oxygen (O 2) • G3P (sugar) • ATP • NADPH
PHOTOSYNTHESIS: • converts light energy to the chemical energy of food 6CO2 + 6H2O + light energy C6H12O6 + 6O2. Happens in all green parts of plants but leaves = major site ~ about half a million chloroplasts/mm2 of leaf surface. Color of leaf due to green pigment chlorophyll.
