Question

A plant in the division Tracheophyta has a sporophyte with

• A. isogametes
• B. roots, stems and leaves
• C. xylem vessels that transport water and nutrients
• D. no independent life

Answer 1

The correct option is B roots, stems and leaves

Tracheophyta includes the plants with vascular tissues such as pteridophytes, gymnosperms and angiosperms. They have a dominant sporophyte phase with roots, stems and leaves. The sporophyte of tracheophytes is independent. Only angiosperms have vessels in the xylem for conduction of water and minerals. Pteridophytes and gymnosperms (except Gnetum) lack vessels. Tracheophytes produce heterogametes. The male and female gametes differ morphologically and physiologically.
