Textbook Question
Textbook QuestionWhich of the following is a characteristic that distinguishes gymnosperms and angiosperms from other plants? (A)alternation of generations (B)independent gametophytes (C)vascular tissue (D)ovules
Verified step by step guidance
1
Identify the unique features of gymnosperms and angiosperms compared to other plant groups.
Understand that both gymnosperms and angiosperms have vascular tissues like many other plants, and they also exhibit alternation of generations, which is common in all plants.
Recognize that independent gametophytes are more characteristic of non-vascular plants like mosses, where the gametophyte is the dominant life stage.
Consider that both gymnosperms and angiosperms produce ovules, which are enclosed for angiosperms and naked for gymnosperms, distinguishing them from other plants that do not produce ovules at all.
Conclude that the correct answer is (D) ovules, as this is a feature that specifically distinguishes gymnosperms and angiosperms from other plant groups.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Gymnosperms and Angiosperms
Gymnosperms and angiosperms are two major groups of seed-producing plants. Gymnosperms, such as conifers, have seeds that are not enclosed in an ovary, while angiosperms, or flowering plants, produce seeds within a fruit. Both groups are characterized by their ability to reproduce through seeds, which provide advantages in survival and dispersal compared to spore-producing plants.

Ovules
Ovules are structures found in seed plants that develop into seeds after fertilization. In gymnosperms, ovules are exposed on cones, while in angiosperms, they are enclosed within the ovary of a flower. The presence of ovules is a key characteristic that distinguishes these seed plants from non-seed plants, which reproduce via spores.

Alternation of Generations
Alternation of generations is a reproductive cycle in plants that involves alternating between a haploid gametophyte stage and a diploid sporophyte stage. This process is common to all plants, including gymnosperms and angiosperms, and is not a distinguishing feature between them and other plant groups. Understanding this concept helps clarify the life cycles of various plant types.
