The term COAT SEED is composed of two words, SESAME (6 letters) and OVULE (5 letters). SESAME is a flowering plant that produces small, flat seeds with a nutty flavor. These seeds are used in many cuisines around the world, and are also used to make SESAME oil. OVULE is a type of seed found in plants, which contains an embryo and is surrounded by a protective coat. It is the precursor to a seed, and is necessary for the plant to reproduce. Together, these two words form the term COAT SEED, which refers to the protective coating that surrounds the OVULE and helps it to develop into a seed.
