(C) Bryophytes and pteridophytes

(D) Angiosperm and gymnosperm

$\huge{\underline{\sf{Answer :-}}}}$

➔ The vascular tissue is absent in (B) Thallophytes and bryophytes.

✮ Reason:

Vascular tissues like xylem and phloem are found in the higher plants. These vascular tissues help in the conduction of food and water through the complex plant body of higher plants.

Roots are seen in higher plants, but they are absent in both thallophytes and bryophytes. Since, thallophytes and bryophytes don't have true leaves, stem and roots, they don't have vascular tissues.

✮ Extra Information:

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.

Answer 2

Thallophytes and Bryophytes have no vascular tissue.

• Non- vascular plants are those that lack a vascular system made up of xylem and phloem. Algae and bryophytes, for example.
• They could instead have simpler tissues with particular functions for water transport within the body.
• The xylem and phloem are vascular tissues found in higher plants. Angiosperms, Gymnosperms, and Pteridophytes, for example.
• These vascular tissues help the plant carry food (through phloem) and water (via xylem) throughout its system.
• Because they are not differentiated into true leaves, stems, and roots, thallophytes and bryophytes lack vascular tissues.
• Algae are simple, thalloid, chlorophyll-bearing autotrophic organisms that are primarily aquatic (both freshwater and marine).
• Bryophytes require water for reproduction and can also survive in soil like a terrestrial plant. Therefore known as the" amphibian of the plant kingdom".
