急!!About photosynthesis

1.What is the use of light reaction and dark reaction?
Ans. as far as sunlight being concerned, it will react with chlorophyll in epidermis of the leaf in plant, as well as carbon dioxide and water through the process of photosynthesis to produce oxygen in the daytime; while the reversed reaction will be taken place by release of carbon dioxide at nighttime.
2.Are all the green plants are able to carry out the process of photosynthesis?
Ans. certainly, it is because green plants in which all carry chlorophyll in their epidermis of the leaf for such process.
3.Can a living thing make food without carry out the process of photosynthesis?
Ans. of course no living thing exists without such process of photosynthesis and in case of most living things can only act as predators preying upon other animals.
And also other information about Photosynthesis !
Ans. it is a very important process for plants because that'll help them to produce carbohydrate for their food.

1.What is the use of light reaction and dark reaction?
→光反應吸收光能產生NADPH和ATP。暗反應利用NADPH和ATP把二氧化碳做成甘油醛(萄葡糖)。
2.Are all the green plants are able to give out photosynthesis?
→原則可。
3.Can a living thing make food without carry out photosynthesis?
→化學合成菌(如硝化菌)。
