which is a trait of all seed plants? vascular tissue rhiziods cambium woody stem

Vascular tissue is a trait of all seed plants.

Explanation:

• Vascular tissue: All seed plants possess vascular tissue, which includes xylem and phloem. This tissue is essential for the transport of water, nutrients, and food throughout the plant.

Incorrect Options:

• Rhizoids: Rhizoids are structures found in non-vascular plants like mosses and liverworts, not in seed plants. Seed plants have true roots instead.
• Cambium: While the vascular cambium is present in many seed plants (particularly dicots and gymnosperms) and is involved in secondary growth, not all seed plants have cambium. For instance, monocots typically lack a vascular cambium and do not undergo secondary growth.
• Woody stem: Not all seed plants have woody stems. For example, many seed plants, like most monocots (e.g., grasses), have herbaceous stems and do not develop woody tissue.
