Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ plants are simple and small plants without a vascular system. ____ plants have a vascular system within them that transport water and food throughout the plant. These plants also have true roots, stems and leaves.
A
Vascular ; Non-vascular
B
Non-vascular ; Vascular
Explanation: 

Detailed explanation-1: -vascular system, in vascular plants, assemblage of conducting tissues and associated supportive fibres that transport nutrients and fluids throughout the plant body.

Detailed explanation-2: -Nonvascular Plants. Nonvascular plants (often referred to collectively as the bryophytes) include three groups: the mosses (Bryophyta), approximately 15, 000 species; liverworts (Hepaticophyta), approximately 7500 species; and hornworts (Anthocerophyta), approximately 250 species (Table 1).

Detailed explanation-3: -Vascular plants are those plants, which have specialised vascular tissues for the transport of water, minerals and food. They contain xylem for water and mineral transport from roots to different parts of the plant and phloem for the transport of food from leaves to other parts of the plant.

Detailed explanation-4: -Algae. Algae are a large group of generally aquatic plants. Like bryophytes, algae are nonvascular: They lack the xylem and phloem tissues that transport fluids and nutrients internally. They do not have leaves, roots or flowers, nor do they have rhizoids or leaflike structures like some nonvascular plants.
