How is respiration different from photosynthesis?

Cellular Respiration: Occurs in all living organisms, the entire process occurs in Mitochondria, Glucose and oxygen are the reactants of this process, Carbon dioxide, water, and energy (ATP) are the by-products, Undergoes Catabolic Process, Oxygen is taken in and carbon dioxide is liberated out, this process does not require sunlight since cellular respiration occurs all the time, In this process, food particles are broken down to release energy.

Photosynthesis: Occurs only in phototrophs (all green plants, algae, and some bacteria),the entire process occurs in Chloroplasts,  Carbon dioxide, water, and light energy are the reactants of this process, Producing food and capturing energy, It is an endothermic reaction as it requires energy, this process requires sunlight since photosynthesis occurs only in the presence of sunlight.

i think a) betsy can donate only blood to mark is correct because, mark and betsy have the same blood type. whereas nobody else has b+ blood so betsy can't donate to them.

meiosis is the correct answer
