The presence of vascular tissue is a distinguishing feature between which two plant groups?

• A. Bryophytes and pteridophytes
• B. Angiosperms and gymnosperms
• C. Bryophytes and angiosperms
• D. Tracheophytes and bryophytes

Answer: (D)

The main idea here is whether a plant has a vascular transport system. Vascular tissue, made up of xylem and phloem, acts like a plumbing network that moves water, minerals, and sugars throughout the plant. Plants with this system are called tracheophytes, and they can grow taller and inhabit a wider range of environments because they can efficiently transport resources. Plants without true vascular tissue—the bryophytes—rely on simple diffusion and are typically small, staying close to moist surfaces because they can’t transport water effectively over long distances.

So the feature that clearly distinguishes these two groups is the presence of vascular tissue in one group and its absence in the other. This pairing highlights the difference between tracheophytes and bryophytes. The other options mix groups where both have vascular tissue or don’t clearly contrast vascular presence, so they don’t show the distinction as cleanly.
