Question

The first terrestrial plants, to possess vascular tissues, among the following are
A. Sphagnum and Selaginella
B. Marchanita and Funaria
C. Selaginella and Salvinia
D. Funaria and Equisetum

Answer 1

Terrestrial plants are the plants that live on land. Pteridophytes are the first terrestrial plant that possesses a vascular system. Pteridophytes include horsetails and ferns. The vascular system also is known as a conductive system.

Step by step answer: Pteridophytes found in cool, damp, and shady places. The leaves in pteridophytes are small or large. They do not produce seeds and are nonflowering plants. Pteridophytes are further classified into Psilopsida, Lycopdida, Sphenopsida, and Pteropsida. Gymnosperms and Angiosperm also possess vascular systems. Selaginella, Salvina, and Equisetum are pteridophytes, so they possess vascular systems. Bryophytes do not possess vascular systems. Bryophytes are divided into liverworts and mosses. Marchantia belongs to liverworts. Funaria and Sphagnum both belong to mosses. Hence Marchantia, Funaria, and Sphagnum do not possess vascular systems.
So, the correct option is (C)Selaginella and Salvinia
Additional Information: Like in humans there are circulatory systems that transport nutrients, oxygen, and waste material throughout the body. Plants also have a system that transports water, mineral, and waste material in the plant; this system is known as the vascular system. The vascular system includes complex tissue called xylem and phloem. Xylem tissue transports water and minerals from the soil to the other parts of the plant. Phloem transport food in the plant from the leaves to the other part of the plant. Bryophytes can live in soil but are dependent on water for sexual reproduction so they are known as amphibians of the plant kingdom.

Note: Advantage of pteridophytes:
-Use for medicinal purposes
-Use as ornamentals
-Use as soil binders
