Question

BlackTom AI · Accepted Answer

Question restatement: Which of the following is a characteristic of all plants?

Option a: They have a vascular system for transporting water and nutrients. While many plants (like flowering plants and ferns) do have vascular tissue, not all plants possess a true vascular system. Non-vascular plants such as mosses, liverworts, and hornworts lack xylem and phloem, so this statement cannot be true for all plants.

Option b: They have flowers for sexual reproduction. This is incorrect because several major plant groups (mosses, liverworts, ferns, and gymnosperms) do not produce flowers. Flowers are a characteristic of many angiosperms, but not universal across all plants.

Option c: They have seeds enclosed in a protective fruit. This describes angiosperms specifically. Many plants reproduce without seeds enclosed in a fruit, such as ferns (spores) and gymnosperms (naked seeds). Therefore, this is not a universal feature of all plants.

Option d: They are multicellular eukaryotes. This is correct because all plants are multicellular organisms with eukaryotic cells containing nuclei and other organelles. This property applies to all plant species, across all major plant groups.

Summary: Options a, b, and c are not universal across all plants due to exceptions in non-vascular plants, non-flowering plants, and seedless or fruitless lineages, respectively. Option d captures a fundamental, universally true characteristic of plants as a kingdom.
