Answer:
The correct answer is reproductive tissue.
Step-by-step explanation:
The flower is a modified shoot of the plants which acts as a reproductive structure in plants.
The flower is a characteristic feature of angiosperms which was evolved as an adaptation to survive. It encloses the gametophytic structure of the plants present on the stamens and carpels. Stamen produces male gametophyte- pollen grains and carpel produces- embryo sac which encloses egg cell.
Thus, reproductive tissue is the correct answer.
