FOCUS ON ENERGY AND MATIER
Life is solar powered. Almost all the producers of the biosphere depend on energy from the sun to produce the organic molecules that supply the energy and carbon skeletons needed for life. In a short essay (100‒150 words), describe how the process of photosynthesis in the chloroplasts of plants transforms the energy of sunlight into the chemical energy of sugar molecules.

Consider a recently discovered planet that scientists believe is capable of supporting life due to its similarities to the earth. However, its daytime temperature and oxygen content in its atmosphere are HIGHER than earth.
Design a plant that can survive and show MAXIMUM photosynthetic efficiency in this planet by enumerating the features (anatomical/metabolic) that you will include and explain why it is necessary to include them.
Photosynthesis Purpose? Why does a plant need water? Why does a plant need CO2 Why does a plant produce O2?

Which plants harness the most energy for photosynthesis? X-ray irradiated plants Blue light irradiated plants Red light irradiated plants Infrared irradiated plantsarrow_forwardQ. 16 Please answer correctly well explained and not from google internet. The first researchers who worked on the process of photosynthesis had difficulty finding the enzyme that performed the fixation of carbon dioxide, because they were looking for an enzyme that could attach CO2 to a two-carbon compound. Explain why these researchers were looking for a two-carbon compound.arrow_forward

Some scientists estimate that at the current rate of population growth, rice farmers will need to produce 50% more rice per hectare by 2050. Researchers are working to increase the photosynthetic efficiency of rice to meet the concern over food shortage. Using your knowledge of photosynthesis, suggest features of the plant and photosynthetic process that could be modified.arrow_forward
- please draw diagram/model Start with a photon of sunlight and a carbon atom in a molecule of carbon dioxide in the atmosphere: model/diagram their pathway from that starting point to their final destination as a glucose molecule that is used for energy in a cell in the plant root. Following your diagram/model, provide a written explanation for what your diagram/model depicts. Make sure both your model and explanation are clear, concise, and have the appropriate level of detail to clearly demonstrate you understand photosynthesis, cellular respiration, and the movement of mass and energy in plants.arrow_forwardLight energy that is capture in photosynthesis is converted to ______ energy stored in chemical bonds of molecules. Potential Sound Solar Kinetic Why do photosynthesizes contain accessory pigments in addition to chlorophyll a? To reflect different wavelengths on the exterior of the photosynthetic organism. To filter light such that only photons of the right wavelength reach chlorophyll a. To absorb wavelengths of light that chlorophyll a cannon and extend the range of the wavelengths captured. To emit energy beyond the capability of the pigment chlorophyllarrow_forwardHi, I am doing a question on photosynthesis and I have a question about the answer that was provided. The question states: If four molecules of CO2 enter the Calvin cycle, how many molecules of G3P are produced, and how many molecules are exported? I know that each turn makes 2 G3P so it would make 8 molecules. When I read the book it said that 3 turns makes 6 and then 1 is exported, so why does 4 turns make 8 and 4 be exported?arrow_forward
