Answer:
The mature male gametophyte in angiosperms is represented by the germinating pollen grain.
Explanation:
Angiosperms: Angiosperms are flowering plants that produce seeds enclosed in a fruit. They are the largest and most diverse group of plants, consisting of around 300,000 species.
Male Gametophyte: In angiosperms, the male gametophyte is produced inside the anthers of the flower. The anthers contain microsporocytes, which undergo meiosis to produce microspores. These microspores develop into pollen grains, which are the male gametophytes.
Mature Male Gametophyte: The mature male gametophyte in angiosperms is represented by the germinating pollen grain. The pollen grain is the mature male gametophyte that contains two haploid nuclei - the generative nucleus and the tube nucleus.
Germinating Pollen Grain: When the pollen grain comes in contact with the stigma of the flower, it germinates and forms a pollen tube. The tube nucleus moves down the pollen tube and helps in the growth of the tube. The generative nucleus divides to form two sperm nuclei.
Conclusion: Thus, the mature male gametophyte in angiosperms is represented by the germinating pollen grain, which contains two haploid nuclei - the generative nucleus and the tube nucleus.
