Which of the following organs or cells components are common to both the sporophytes and the gametophytes of a fern?

The option that is common to both sporophytes and gametophytes of a fern is chloroplasts. Chloroplasts are organelles found in plant cells and some algae that are responsible for photosynthesis. Both sporophytes and gametophytes in ferns have chloroplasts which enable them to produce food (carbohydrates) through photosynthesis. Rhizoids are root-like structures that are found in gametophytes of ferns, while roots are only found in sporophytes. Leaves are also only found in sporophytes of ferns. Therefore, chloroplast is the correct answer.
