Verified step by step guidance1
Understand the difference between seeds and spores: Seeds are multicellular structures that contain an embryo, a food supply, and a protective coat, while spores are typically unicellular and lack these features.
Recognize the advantages of seeds: Seeds provide a food supply for the developing embryo, which helps ensure successful germination and growth under favorable conditions.
Eliminate incorrect options: Seeds are not produced only by non-vascular plants; they are produced by vascular plants like gymnosperms and angiosperms. Seeds do not require water for fertilization, unlike spores in some plants like mosses and ferns. Seeds are not unicellular; they are multicellular structures.
Focus on the correct answer: The key advantage of seeds is that they provide a food supply for the developing embryo, which is critical for its survival and growth.
Conclude with the importance of seeds: Seeds represent an evolutionary advancement over spores, allowing plants to reproduce more effectively in diverse environments without relying on water for fertilization.
