Which phylum of the plant kingdom consists of vascular plants, leaves (known as fronds), roots and sometimes true stems and entire trunks in tree ferns?

Pteridophyta

The correct answer is Option (2) - Pteridophyta

The phylum of the plant kingdom that consists of vascular plants with leaves (known as fronds), roots, and sometimes true stems, including entire trunks in tree ferns, is Pteridophyta.

Pteridophytes are a group of vascular plants commonly known as ferns. They exhibit well-developed vascular tissues (xylem and phloem) for the transport of water, nutrients, and photosynthetic products. The characteristics of Pteridophytes include the presence of fronds (large compound leaves), roots, and, in some cases, true stems.

Pteridophytes play a significant role in ecosystems, contributing to soil stability and providing habitat for various organisms. Tree ferns, in particular, can develop substantial trunks and are often found in tropical and subtropical regions.

It's important to note that the other plant groups mentioned—Angiosperms, Gymnosperms, and Bryophytes—represent different phyla within the plant kingdom.

• Angiosperms: Flowering plants that produce seeds enclosed within a fruit.
• Gymnosperms: Seed plants with "naked" seeds, not enclosed within a fruit.
• Bryophytes: Non-vascular plants, including mosses and liverworts, lacking true roots, stems, and leaves.
