What is the Difference Between Fruit and Seed?

🆚 Go to Comparative Table 🆚

The main difference between a fruit and a seed lies in their origin and structure. Here are the key differences:

  • Origin: A fruit is the ripened ovary of a plant, formed from the fertilized ovary of an angiosperm, while a seed is a fertilized ovule, containing the embryo and stored food to sustain it through germination and early development of the seedling.
  • Structure: A fruit has two major portions: the pericarp and the seed, while a seed has three portions: the seed coat, endosperm, and embryo. The fruit is enclosed by an exocarp, while the seed is enclosed by a seed coat.
  • Purpose: Fruits help in seed dispersal by attracting animals, while seeds can grow into a new plant. Without seeds, the fruit cannot grow into a new plant, but without the fruit, the seed can still grow into a new plant.

In summary, a fruit is the ripened ovary of a plant that contains seeds, while a seed is a fertilized ovule containing the embryo and stored food for germination and early seedling development. Both fruits and seeds play crucial roles in the plant's reproductive cycle.

Comparative Table: Fruit vs Seed

Here is a table comparing the differences between fruits and seeds:

Characteristic Fruit Seed
Origin Formed from the ovary of a flower Formed from the ovule of a flower
Attachment Scars Shows two scars for attachment Shows one scar for attachment
Inside Contents Contains seed(s) Embryo is present inside
Protection Protects the seed Seeds are present inside the fruit
Classification Classified into simple, aggregate, and multiple fruits Classified into naked and enclosed seeds
Role in Plant Attracts animals for seed dispersal Reproduction of gymnosperm and angiosperm plants

Fruits are the mature ovaries of flowering plants, usually containing seeds, and serve to attract animals for seed dispersal. Seeds, on the other hand, are the fertilized ovules of plants, containing an embryo, and are responsible for the reproduction of gymnosperm and angiosperm plants.
