True or False, Photosynthesis is used by flowering plants to make energy by converting the sun's energy?

I read this question in a science book, and it stated that the answer is false. Don't flowering plants use photosynthesis?

True or False, Photosynthesis is used by flowering plants to make energy by converting the sun's energy?
Overall the statement is true however the reason it could be false is because of the term "make energy" which has been used, according to the law of conservation of energy, energy cannot be created or destroyed it can only be changed in form, so in relation to the question, the plant doesnt make energy it absorbs light and this energy is captured and transferred to a molecule of glucose which is the main storer of energy, this can be broken down to release energy
Reply:The answer is true.


Photosynthesis - a set of chemical reactions only a plant containing the pigment chlorophyll can perform. The plant takes energy from the sun that comes in contact with leaves in the form of light, combines it with carbon dioxide from the air and water from the soil to make a sugar called glucose. They use this as their food source and are the only living creatures on Earth that have this ability. Every other life form depends on plants for food supply.


generally, is the synthesis of sugar from light, carbon dioxide and water, with oxygen as a waste product. It is arguably the most important biochemical pathway known; nearly all life depends on it. It is an extremely complex process, comprised of many coordinated biochemical reactions. It occurs in higher plants, algae, some bacteria, and some protists, organisms collectively referred to as photoautotrophs.
Reply:I think its true
Reply:All plants use photosynthesis to some degree or another, even carnivorous plants like the venus fly trap. That's one of the defining features of plants.
Reply:Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll.





The answer is correct because they don't make energy they make ATP or a form of sugar.
Reply:yes, wtf!
