An important similarity between photosynthesis and cellular respiration is that both processes

Answer;

-They use and make ATP

Explanation;

-Photosynthesis is the process by which plants make their own nutrients using energy from the sun light. Solar energy from the sun together with water, carbon dioxide are used to make organic compounds such as glucose and oxygen as a by product.

-Cellular respiration involves the break down of nutrients such as glucose to yield energy in form of ATP, that is used by the cells to drive cellular processes, such as transport and growth.

-In both of the stages of photosynthesis and in aerobic respiration, glucose is the energy used to create ATP.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
