Verified step by step guidance1
Understand the question: The problem is asking which characteristic is unique to seed-producing plants. This means we need to identify a feature that is exclusive to plants that produce seeds and not shared by other types of plants.
Analyze the options: Review each characteristic provided in the options to determine if it is unique to seed-producing plants or if it is shared by other plant groups.
Option 1: 'Cell walls made of cellulose' - This is a characteristic of all plants, not just seed-producing plants. Therefore, it is not unique to seed-producing plants.
Option 2: 'Presence of chlorophyll' - Chlorophyll is present in all photosynthetic plants, including non-seed-producing plants like mosses and ferns. Thus, it is not unique to seed-producing plants.
Option 3: 'Presence of flowers or cones' - Flowers and cones are reproductive structures that are specific to seed-producing plants (angiosperms and gymnosperms, respectively). This characteristic is unique to seed-producing plants and distinguishes them from non-seed-producing plants like mosses and ferns.
