In photosynthesis, what is the main purpose of the light reactions? a. To produce oxygen b. To produce sugars c. To produce NADPH and ATP d. To take in water e. To take in carbon dioxide What is photosynthesis? How does it work?
Photosynthesis is performed by organisms that contain the pigment chlorophyll. Chlorophyll is a green pigment that is able to absorb light energy from the sun. This provides the initial energy necessary to carry out other chemical reactions.
1 The process of photosynthesis has two main stages. The first of these involves the light-dependent reactions(a) The statements below describe important parts of the light-dependent reactions of photosynthesis. Place a cross 区in the box next to the term that completes each statement correctly....

Well, it's maybe a billion years after Earth's formation that we first see evidence of life. Of course early life forms were primitive, just tiny, single-celled microbes, but overtime, they had a profound effect. Huge numbers of these microbes began producing food by photosynthesis, which ...
Leaves get their green color from chlorophyll, the chemical that's responsible for photosynthesis. 树叶是绿色通常是因为叶绿素这种物质,它有助于光合作用。 The chlorophyll in the leaves collects energy from the Sun in the form of sunlight and it converts this energy into sugar which is food for ...

1.What is the main purpose of the lecture? A. To explain how the red pigment in leaves breaks down B. To show that leaf color varies based on the tree species C. To introduce a theory about why leaves turn a particular color D. To explain how chlorophyll protects trees in autum...
began producing food by photosynthesis, which, of course, also freed up enormous amounts of oxygen. And lots of that oxygen interacted with the atoms of existing minerals, creating rust out of iron, for instance, … reacting with a whole range of different metals to create lots of new ...
