Photosynthesis and chloroplast questions and answers

1. What is the primary function of photosynthesis?
The primary function of photosynthesis is to capture light energy, convert some of this light energy into chemical energy, and store this chemicalenergy in molecules of carbohydrates (such as phosphoglyceraldehyde, glucose, or starch).
2. What would happen to humans and most other living organisms on Planet Earth if photosynthesis stopped?If photosynthesis stopped, most living organisms on Planet Earth, including humans, would die due either (A) to a shortage of energy because no food molecules would be available or (B) to a shortageof oxygen for cellular respiration.
3. Chlorophyll is green because it _?_ (absorbs, reflects, or transmits) green wave lengths of light.
Chlorophyll is green because it reflects green wavelengthsof light and these are what we see
4.What is the range of wavelengths of light that are visible to humans?
The wavelengths of light that are visible to humans range from approximately 400nanometers (violet) to 700 nanometers (red). Some animals can see additional wavelengths. For example, some insects can see ultraviolet light.
5.what means phosphorylation
The term phosphorylation refersto the addition of a phosphate group to an atom or molecule. The addition of the phosphate involves the addition of large amounts of energy. This energy may come from light (as in the light reactionsof photosynthesis) or from the breakdown of sugars (as in cellular respiration).
6.Exactly why is photosynthesis so important?
Two big reasons. One product of photosynthesis is glucose (sugar),which provides the basis for most food chains. The second product of photosynthesis is oxygen which comes in handy if your happen to be an aerobic organism that requires oxygen for survival.
7.Wheredoes photosythesis occur?
This question can be answered on various levels.
On the planetary level, most photosynthesis occurs in the oceans, because the oceans occupy the vast majority (70%) of the...
