According to the graph below, at which point is the plant performing the most
photosynthesis?

a. point c
b. point a
c. point b
d. point d

Point C

Explanation:

Oxygen is a by-product of photosynthesis, so when the oxygen production is at its highest, photosynthesis is also at its highest.

A. Point C

Explanation:

The plant which is evolving most oxygen is performing the most photosynthesis because during photosynthesis inorganic carbon dioxide and water react in the presence of sunlight to synthesis organic molecule known as glucose and oxygen is evolved.  

The reaction for photosynthesis is depicted as under:

      6CO₂       +   6H₂O    +  sunlight      →    C₆H₁₂O₆    +     6O₂

   (carbon          (water)                                 (glucose )       (oxygen)

   dioxide)  

So, more evolution of O₂ (oxygen) implies more photosynthesis.

good one: produce hormones that plants grow.

bad one: the problem with organic matter is that while plant nutrients are needed for crop growth, they can also stimulate excessive growth of the wrong plants – mainly, algae.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
