Detailed explanation-1: -In pteridophytes, the main plant body is a sporophyte which is differentiated into true root, stem and leaves. These organs possess well-differentiated vascular tissues .

Detailed explanation-2: -Sporophytes are referred to as spore-producing plants. However, it is important to take note of the fact that all plants produce spores. Plants that have sporophytes are classified as non-vascular and vascular plants, and are further categorized into different botanical phyla.

Detailed explanation-3: -Assertion :The main plant body of bryophytes is gametophyte.

Detailed explanation-4: -The main plant body of the bryophyte is haploid. It produces gametes, hence is called a gametophyte. The male and female gametes fuse together to form zygote. The zygote produces a multicellular body called a sporophyte which is diploid.

Detailed explanation-5: -Here, the main plant body is sporophyte which can be well differentiated into roots, stem, and leaves. In the life cycle of a plant, the diploid multicellular stage is called the sporophyte. The sexual phase in the life cycle of a plant is gametophyte which produces gametes.
