Flower Fruit and Seed
Seed Formation: After Fertilisation, the zygote grows to become an embryo. The embryo develops into a seed ( mature ovule) while the surrounding ovary develops into a fruit. The embryo consists of a plumule, radicle and an embryonic axis to which two fleshy cotyledons are attached. The cotyledons store food for the embryo. Seeds are attached to the fruits by a stalk. The stalk on maturity becomes detached and leaves a scar called hilum. Seeds are covered by a protective layer called the seed coat. When a seed gets suitable temperature, air and water, it germinates and grows into a new plant. This process is called germination. The plumule develops into the shoot system whereas the radicle grows as the root system.
Fruit Formation: The ovary grows into a fruit. The fruit is actually a ripened and mature ovary, generally sweet, juicy or pulpy. It encloses seeds. Some fruits are fleshy and juicy such as mango, apple, peach, orange, etc. Almonds and walnuts have hard and woody shell of nuts. These are the examples of hard fruits or dry fruits. After fertilization the ovary enlarge to from the fruit.
