Tracheophyte includes _______.
A. Pteridophyte, gymnosperm and angiosperm
B. Bryophytes and spermatophyte
C. Only spermatophyte
D. Thallophytes and bryophytes
Solution
The division of tracheophytes is distinguished by the presence of vascular tissues essential for water, minerals and food. The vascular tissues include xylem and phloem. They are conducting tissues of plants. It is made up of both living and dead cells.
Complete answer: Vascular plants are also referred to as tracheophytes and are classified as terrestrial plants. They can be linear or nonlinear and can have real roots, stems and leaves. They produce diploid spores. The whiskey ferns, which are Sphenopsida consist of feathery leaves, lycopods contain gymnosperms (spruce, pine and fir), ferns and flowering plants are low-lying club mousses and Pteropsida. The presence of well-formed vascular tissues (xylem and phloem) in lower plant groups indicate that vascular plants or tracheophytes are more abundant in nature. They also produce seeds and fruit and have a reproductive system and can grow into a new plant. The vascular system is used for transportation purposes. Water and minerals are transported through xylem and food and nutrients are transported through the phloem. The vascular system is seen in higher plants.
Hence, option A is the correct answer.
Note: Tracheophytes/vascular plants are thought to have been developed from chlorophytes (green algae). The first Silurian fossil is approximately 400,000,000 years old. This is due to the fact that the tracheophytes remain upright because of the flow of water and food through xylem and phloem tissues.
