Which statement best describes the relationship between photosynthesis and cellular respiration?
photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.
photosynthesis is part of the carbon cycle, and cellular respiration is not.
only plants perform photosynthesis, and only animals perform cellular respiration.
photosynthesis releases carbon into the atmosphere, and cellular respiration removes carbon from the atmosphere.

The correct answer will be option photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.

Explanation:

Photosynthesis is a process by which plants and other photo-autotrophs    synthesize food using water and carbon dioxide from the environment in the presence of sunlight. Photosynthesis releases O₂ in the atmosphere.

6CO₂+ 6H₂O → C₆H₁₂O₆+ 6O₂.

Respiration is a process of oxidation of food or glucose to form energy molecule using oxygen. Respiration releases CO₂ in the atmosphere.

C₆H₁₂O₆+ 6O₂ → 6CO₂+ 6H₂O + ATP.

Since, photosynthesis use carbon dioxide from the atmosphere to make food while respiration uses oxygen and releases carbon dioxide to the atmosphere therefore, photosynthesis removes carbon from the atmosphere while cellular respiration releases carbon back into the atmosphere is the correct answer.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
