Question

Vascular and mechanical tissue is absent in_____________.

• A. Bryophyta
• B. Pteridophyta
• C. Gymnosperms
• D. Angiosperms

Answer 1

The correct option is A Bryophyta

Pteridophytes have a well-differentiated plant body with vascular tissues. Therefore, option B is incorrect.
Gymnosperms have a well-differentiated plant body with vascular tissues. They produce naked seeds. Therefore, option C is incorrect.
Angiosperms have a well-differentiated plant body with vascular tissues. They produce seeds enveloped in fruits. Therefore, option D is incorrect.
Bryophytes have a well-differentiated plant body with stem and leaf-like structures. They do not have conducting or vascular tissues, i.e, xylem, and phloem. Thus, they are called non-vascular cryptogamic plants. They are very small in length usually 2 cm to 15 cm. So they do not need mechanical tissues. Therefore, option A is correct.
