1. What does photosynthesis do for the plant? 2. What does cellular respiration do for the plant?

Explanation:

1.Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.

2.The process of cellular respiration allows plants to break down glucose into ATP. The ATP provides the energy they need to carry out various functions. Although plants use photosynthesis to produce glucose, they use cellular respiration to release energy from the glucose

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
