is found only in plants. a. Glycogen b. Lactose c. Cellulose d. Glucose e. Fructose

c.cellulose

Explanation:

it makes the cell walls of the plant cells whuch is abscent in animal cell.

D. Glucose

Explanation:

The storage form of glucose in plants is starch. The energy from the sunlight is used to make energy for the plant. So, when plants are making sugar (for fuel, energy) on a sunny day, they store some of it as starch. The process of photosynthesis is essential for all living things in the world, and plants are the only food-producers, while the other animals either feed on plants or feed on other animals. The glucose produced is then stored in the leaves as starch.

energy per photon is e = h*c / λ  

e = 6.63*10^-34 * 3*10^8 / 6*10^-7 j = 3.315*10^-19 j  

nr. of photons = 10j / 3.315*10 = ^-19 j per photon = 3.02*10^19 photons
