Chloroplast is defined as an organelle found in green plants that contains green pigment called chlorophyll responsible for the process of photosynthesis.

Chloroplasts plays an important role in photosynthesis which is to trap light energy from sunlight and convert it into carbohydrate which further used by cells in teh form of adenosine triphosphate  (ATP) and  nicotinamide adenine dinucleotide phosphate hydrogen (NADPH).

Hence, the correct option is B.

answer: a. a gene that causes a specific trait.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
