The main plant body of Pteridophytes is
Open in App
Solution
The correct option is B Sporophyte
Pteridophytes are vascular plants and have leaves (known as fronds), roots and sometimes true stems, and tree ferns have full trunks. Examples include ferns, horsetails and club-mosses. 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. A sporophyte is a diploid multicellular stage in the life cycle of plant including Pteridophytes which develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes. Hence option A is correct.
