Cotyledons are the embryonic leaves found in a seed and are responsible for absorbing nutrients until the plant can produce its own food through photosynthesis. Synonyms for cotyledons include seed leaves, embryonic foliage, first foliage, and primordial leaves. Cotyledons can also be referred to as germination leaves, embryonic shoots, or embryo foliage. These terms are commonly used in botany and biology to describe the first leaves that emerge from a germinating seed. Understanding the synonyms of cotyledons can help students and researchers better communicate about the structures and processes involved in plant growth and development.
