उत्तर
- The outer layers of the ovule become impervious and hard and function as a seed coat. An ovule with an embryo inside is called a seed.
- The ovary enlarges and ripens to become a fruit. Other floral parts such as sepals, petals, stamens, styles, and stigma may fall off. However, in some cases, they remain persistent in the fruit.
